60 PCU 7718 Installation Guide Overview Overview Baseboard Input/Output The Model 7718 Process Control Unit (PCU) from TAC is a high-speed, fully distributed microprocessor-based controller, which is used with the TAC I/NET integrated network system. The 7718 is designed to connect directly to the controller LAN working with all other controllers and workstations on the TAC I/NET LAN. The 7718 supports over 200 addressable points to provide full adaptive Direct Digital Control (DDC), energy management, and process control in a single controller. The 7718 is based on a monolithic board design that combines processing, memory management, communication, and field input/output functions on a single printed circuit board. The controller features removable terminal blocks, downloadable firmware, on-board modem drivers, and a direct connect RS232 port. The inherent reliability of this monolithic design is further enhanced with extensive transient protection, automatic self-test features, and a fiber optic communication option. The 7718 is capable of supervising and controlling over 200 addressable points. The I/O configuration flexibility provided by the PCU allows it to interface with a variety of industry-standard I/O devices. The 7718 supports the following hardwired I/Os: The eight universal inputs on the base unit can be defined as the following types: Analog Discrete Pulse The eight universal outputs can be defined as the following types: Discrete Voltage Momentary PWM Analog (voltage) Communication The 7718 provides up to four communication ports, as follows: TB3 This port provides a standard synchronous RS485 controller LAN connection on the 7718 baseboard Two asynchronous serial ports on the 7718 baseboard. These ports provide access to external PCs, external modems, and the HC7410 Hand Held Console (HHC). P4 This asynchronous RS232 port allows direct connection to a PC or external auto-answer (Hayes -compatible) modem. These connections allow the 7718 to perform the functions of a 7801 host Tap without consuming a 2010 Schneider Electric. All rights reserved. 1
Overview PCU 7718 Installation Guide second LAN address or additional hardware. Refer to TCON101, TAC I/NET Tap and Repeater Installation Guide, for a description of the Direct-connect and Integrated Dial functions of the 78010 Tap. The RS232 port s baud rate is set via the connection of a standard TAC HHC. P1 This asynchronous port provides a modular TTL-level interface to a standard HHC and operates at 1200 baud. P2 This port provides an interface to an optional RS232 Serial Expansion Module. This plug-on board provides an RS232 serial port that can be used to connect an external modem (synchronous or asynchronous) or one of several communication multiplexing devices (refer to RS232 Serial Expansion Module on page 8). Reset Expansion Board Input/Output Options Upon power loss/restoration, the PCU executes an automatic reset memory test of RAM and EPROM. The test uses an array of RAM test bytes and a Checksum check on the EPROM, and if the check is successful, control and execution are passed to programmed memory. A manual reset that is started by pressing the reset button executes the same tests. Expanded I/O capability and flexibility are provided via an expansion port that supports the control of additional I/O points providing a number of I/O options. The expansion board modules that are available are: A universal input, discrete voltage output (E8UI8DO) expansion module is available, providing an additional eight inputs and eight outputs. A universal input (E16UI) expansion module is available, providing 16 additional input points. 2 2010 Schneider Electric. All rights reserved.

Physical Description PCU 7718 Installation Guide Universal Enclosure TAC s Universal Enclosure provides a protected environment in locations in which dirt, dust, or other contaminants may exist. TAC Universal Enclosures are available in several sizes designed to house various combinations of TAC control units and interfaces. The model used for the 7718 is the ENCL1813, measuring 18.25" H 13.25" W 4.20" D (46.2 33.5 10.7 cm) The Universal Enclosure allows both door and back panel mounting, providing additional space for optional equipment such as transformers and electrical junction boxes. The enclosure includes a door key lock. The 7718 board comes already mounted on a baseplate. That baseplate/pcb assembly is then mounted into the Universal Enclosure. If the perforated backplane is used to mount the baseplates, then the size of the baseplates and the enclosure are the limiting factors. Baseplates vary in dimension depending upon the type of controller. All controllers and interface units are attached to a baseplate for mounting in a Universal Enclosure. Universal Enclosures are available in varying capacities and sizes. Table 1. Universal Enclosure Dimensions Model Panel Dimensions Standard Door Mounting Baseplate Qty Perforated Panel Backplane Dimensions H W D H W Panel Backplane w/studs Door Key Lock ENCL1813 W/Knockouts and Gasketed Door 18.25" 13.25" 4.2" 1 Any TAC baseplate unit 16.5" (number 8 32 hardware for Optional Panel mounting) 12.5" Mount one (max.) TAC baseplate unit Options: 1 Transformer 1 Junction box Yes Power Supply Electrical power for the 24 VAC input power enters at TB4, at the lower left side of the controller. The 7718 is powered from a single 24-volt AC 40 VA external transformer. The AC input provides power to five on-board supplies. The power options for the 7718 are shown below and in Table 2. A switching power supply circuit is used to generate the +5 VDC logic power. Four linear power supplies are used to generate the +15 VDC Internal, +15 VDC External, 15 VDC, and +24 VDC External voltages. These supply voltages are used for analog signal processing and RS232 communication. The separate +15 VDC (external) regulator supplies current loop excitation power to avoid loss of communication due to a field sensor wiring problem. The optional external power supply (a separate 24VAC transformer or DC power supply) provides 24 VDC regulated or unregulated VDC to the discrete outputs. Regulated 24 VDC power is limited to a total current output of 0.25 A maximum, and the unregulated DC load (from an external 24VAC supply) is limited to a total of 0.75 A. Use an external 24 VDC power supply to power the outputs on the E8UI8DO Expansion Board, and to provide a higher total (2.0 A maximum) current capacity. 4 2010 Schneider Electric. All rights reserved.
PCU 7718 Installation Guide Physical Description Selection of regulated or unregulated power is done by moving the plug-on jumper at J25 (refer to Configuring for Unregulated Power on page 25). Power line selection (50/60 Hz) is available using the HHC. The 7718 provides input termination for the connection of an optional external 24 VDC power supply. The optional external power supply must be used to power the output circuits on the E8UI8DO Expansion Board. Use an external DC power supply when you need a higher current capacity than the 0.25 A total provided by the on-board supply. When using the external power supply, the outputs may not exceed a total output current of 2.0 A. Table 2. Discrete Output Power Supply Options Power Supply Available Power (maximum) Power From On-board supply (no connection to external power supply) External AC or DC power supply External DC supply 0.25 A Regulated on-board DC power (+24 VDC) 0.25 A On-board AC power 0.75 A External AC 0.75 A Unregulated on-board DC (31 39 VDC)* 2 A External +24 VDC supply to baseboard outputs 2 A External +24 VDC supply to E8UI8DO expansion board outputs Input/Output Terminals Input Terminations * The unregulated DC voltage available on the discrete outputs depends on the external supply voltage and discrete output loading. Output Terminations The 7718 s input and output terminals are located in different areas of the board. The inputs and outputs do not use the same number of terminals to make up a terminal set. See Figure 23 on page 32 for terminal locations. Signal inputs are provided along the upper left side in two groups of four inputs (TB1 and TB2). Three screw terminations are provided for each input. Two of these terminations are inputs for Signal and Ground. The third terminal is an output for the external field sensor +15/24 V excitation. The inputs (analog, discrete, or pulse) use point addresses 0000 through 0007. There are two types of output terminations available on the 7718, Discrete Voltage Output and Analog 0 10 VDC output. Discrete Voltage Outputs Eight universal output terminations are provided along the upper right side of the controller (TB6). An output termination consists of a single output termination screw. A common termination screw is provided on the board for a ground/common return. Each output consists of a voltage sourcing circuit capable of handling 0.25 A at 24 VDC. 2010 Schneider Electric.

Physical Description PCU 7718 Installation Guide Note: The total combined output currents using the on-board, regulated 24 VDC power supply is 0.25 A, and 0.75 A when using the unregulated supply. When using an external 24 VDC supply for the outputs, the total combined output may be increased to a maximum of 2 A (0.25 A per output). Communication Ports Each output provides discrete control of a field contactor or a proportional control through pulse-width modulation (PWM) of the output contact. The discrete outputs use point addresses 0000 through 0007. Analog 0 10 VDC Outputs Serial Communication Port The 7718 PCU also has eight 0 10 VDC analog outputs available at TB6 (see Figure 23 on page 32). You may use these analog outputs to replace the corresponding discrete voltage outputs on TB6. This is done by moving the desired jumper (J17 J24) from the A B position (discrete output selection) to the B C position (0 10 VDC analog output selection) for each output to be changed. For example: moving only J17 from position A B to position B C places analog output number 1 onto TB6-1. Terminals 2 through 8 of TB6 remain discrete voltage outputs 2 through 8. The analog outputs use point addresses 3100 through 3107. There are three communication ports on the 7718 board, and an optional communication board that can be added as a plug-on daughterboard. All connections to the LAN, modems, external PCs and the HHC are made using these ports. See Figure 23 on page 32 for port locations. The two asynchronous serial ports (on the 7718 baseboard) provide access to external PCs, external modems, and the HHC. Modem and PC Connection The first asynchronous port (P4) provides an RS232 port for direct connection to a PC or external auto-answer (Hayes-compatible) modem. The RS232 port s baud rate is set via the connection of a standard TAC HHC. Hand Held Console Connection LAN Communication Port The second asynchronous port (P1) provides a modular TTL-level interface to the standard HHC and operates at 1200 baud. An RJ11 modular jack is provided along the lower left side of the controller for connection of the TAC HHC. The LAN communication port (TB3) is located along the lower left side of the controller under the input terminal TB2. A 3-pin terminal block provides connection of the RS485 shielded, twisted pair on the standard controller. The normal speed of communication on the controller LAN is 19,200 baud. The controller LAN speed can be lowered to 9600 baud using the HHC in order to accommodate lower grade cable installations. 6 2010 Schneider Electric. All rights reserved.
PCU 7718 Installation Guide Physical Description Memory The 7718 also provides support for several types of memory with variable amounts of each. The memory is currently organized as follows: Table 3. 7718 Memory Socket Amount Memory type U4 32 KB EPROM (stores boot firmware) U1, U2 and U3 96 KB STATIC RAM (stores download software and database. Memory is allocated dynamically.) Static RAM Expansion Modules The 7718 also provides 256 bytes of serial nonvolatile RAM (NOVRAM) memory storage. This memory is used to hold all parameters necessary to establish basic communication with the controller after a long-term power outage (i.e., loss of RAM memory). The software may be downloaded while the 7718 is on the TAC I/NET LAN. The software design and memory organization supports the complete download of all software including revised LAN drivers which are invoked after completion of the download. The downloaded software is held in RAM. When the 7718 is emulating a 78061 Tap, it can store the telephone numbers a standard 78061 Tap would. Memory is sized to insure accommodation of at least eight telephone numbers of at least twenty-five digits each. The base unit configuration of the 7718 provides a minimum of 96 KB of battery-backed static RAM for software data storage and imbedded 7801, 78035 and 78061 Tap functions such as message queue, dial telephone numbers, and async/sync communication buffers. Memory Exhaustion Warning The PCU editors provide a warning message when the user adds a point or function that could exceed the available PCU memory. The 7718 can be expanded by adding one or more expansion modules to the controller s expansion ports. The RS232 Serial Expansion Module connects at port P2, the other I/O expansion modules connect to the 7718 motherboard at port P3. Available I/O expansion modules include: E8UI8DO I/O Expansion Module E16UI Expansion Module RS232 Serial Expansion Module E8UI8DO Expansion Module The Eight Point Universal Input/Eight Point Discrete Output (E8UI8DO) Expansion Module provides an additional eight inputs and eight voltage sourcing outputs on an I/O expansion board that attaches to expansion port P3 at the lower end of the controller 2010 Schneider Electric.

Physical Description PCU 7718 Installation Guide E16UI Expansion Module RS232 Serial Expansion Module PCB. The expansion module card is 3.25" L 8.60" W (8.25 21.8 cm). It attaches on top of the 7718 with standoffs supplied with the module. Signals are passed from the E8UI8DO through a ribbon cable between the terminals of the two boards. The input and output points on the E8UI8DO expansion board occupy point addresses 0100 through 0107. The outputs are defined in the database as your choice of analog (PWM) or discrete outputs. The current requirements of the discrete outputs are separate from the maximum values for the motherboard. The inputs are shipped as 0 5 volt, but may be redefined on the expansion module by changing the resistors in resistor strip sockets A, B, and C. Refer to Universal Inputs on page 41 for more information. They are also defined in the database as analog, discrete or pulse. The Sixteen Point Universal Input (E16UI) expansion module provides sixteen universal (analog or contact) inputs. The expansion module card is 3.25"L 8.60" W (8.25 21.8 cm). It attaches on top of the 7718 with standoffs supplied with the module. Signals are passed from the E16UI through a ribbon cable between the terminals of the two boards. The input points on the Sixteen Point E16UI Expansion Board occupy point addresses 0100 through 0107 and 0200 through 0207. Inputs are shipped as 0 5 V and may be configured as 0 10 V or 0 20 ma current input by inserting precision resistors into resistor strip sockets A, B or C. Refer to Universal Inputs on page 43 for more information. The RS232 Serial Expansion Module provides a fourth serial interface with a full complement of modem control, data and clock signal on an RS232 port. It provides two-way dial or dedicated line communication as currently supplied by TAC s 78061 or 78035 Tap. The data rate is user-selectable up to 9600 baud. This optional interface can be connected to any of the following devices: External auto-dial/auto-answer (AD/AA) modem When connected to a Hayescompatible AD/AA modem, the 7718 will provide the functionality of the 78061 Tap. The following types of modems are supported: Synchronous Use a synchronous modem when the controller is loaded with a TAC I/NET version 4.x or earlier binary file. The controller must also have TAC I/NET version 4.x boot firmware (EPROM). Asynchronous Use an asynchronous modem when the controller is loaded with a TAC I/NET 2000 or later binary file. The controller must also have TAC I/NET 2000 or later boot firmware (EPROM). Note: Ensure that all AD/AA Taps within your TAC I/NET system are configured to use the same communication protocol either synchronous, or asynchronous. Mixing AD/AA protocols will cause communication errors. 8 2010 Schneider Electric. All rights reserved.
PCU 7718 Installation Guide Physical Description TAC I/NET 2000 is compatible with TAC I/NET version 4.x Tap and controller binary loads. Therefore, when synchronous AD/AA communication is required on a TAC I/NET 2000 system (for example, when using a 78040, 78050, or 78060 Tap), you must continue to use TAC I/NET version 4.x Tap and controller binary loads. External synchronous dedicated line modem When connected to an external Hayes-compatible dedicated line modem, the 7718 provides the functionality of a TAC 78035 Tap. Refer to TCON101, TAC I/NET Tap and Repeater Installation Guide, for a complete description the 78035 Tap function. Another RS232 data communication device. 2010 Schneider Electric.

Setting the Voltage PCU7718 E8UI8DO E16UI You may select whether to provide +15 or +24 volts with a maximum load of 160 ma to sensors connected to the 7718 PCU. When using Lini-Temps (which require +15 V) and 0 20 ma sensors that require 24 V, or if more than eight 0 20 ma sensors are used, then an external power supply must be used. You must also configure jumper J31 for 15 V or 24 V power. All terminals on the input connection blocks TB1 and TB2 on the 7718 PCU baseboard will be set to the +15 V or +24 V selection. You may select either +15 or +24 volt power provided by the 7718 PCU to a connected sensor by positioning a jumper on J31 (see Figure 23 on page 32). To achieve +15 volts, position the jumper on posts B and C. Position the jumper on posts A and B to achieve +24 volts. You may select either +15 or +24 volt power provided by the E8UI8DO by positioning a jumper on J9 (see Figure 30 on page 41). To achieve +15 volts, position the jumper on posts A B. Position the jumper on posts B C to achieve +24 volts. Jumper position J10 is used to select the pull-up voltage used by the B resistor positions. When using J10 the pull-up voltage may be set to 5 V or 15 V. On the E16UI Expansion Board jumper J9 is used for TBX1 and TBX2, while jumper J11 is used for TBX3 and TBX4.

E8UI8DO 24 VDC External Power Connections Field Hardware Checkout and Addressing Connecting the HHC Note: Field hardware checkout is essential before any piece of mechanical equipment can begin to be controlled by the 7718. This checkout ensures that: the field devices are working correctly, and they are correctly wired to the 7718. After successful checkout of the field hardware, the unit is ready to start controlling the mechanical equipment and final terminations to actual field devices can be completed. Use an HHC to perform all hardware checkout and addressing of the 7718. Connections between the 7718 and the HHC are made using an RJ11 connection (P1) on the 7718 PCB. Set the address of the 7718 before connecting it to the LAN. 1. Apply power to the 7718. 2. Plug the HHC into the 7718 s RJ11 port at P1 (CONSOLE) on the 7718 PCB using the silver cord (P/N: 602135-0003). 3. Press the [CLEAR] key on the HHC. The display will show the PCU time in 24-hour format, updating every second if the unit is operating properly. When the 7718 is powered up, it attempts to reconfigure the controller LAN and becomes part of it. As it does so, LED 7 (RECON) flashes intermittently. 28 2010 Schneider Electric.

Set Up and Operation PCU 7718 Installation Guide Set Up and Operation This chapter describes the various components of the 7718. This unit mounts indoors on a wall surface in an area that meets the specifications outlined (refer to Specifications on page 59). You should set the unit s address after first powering up the unit and prior to connection to the controller LAN. Identify and record input and output terminals and addresses with their physical terminal block and pin numbers. Also identify the devices to which they connect. Write this information on a copy of the Pinout Chart included in this Installation Guide on page 56. The locations of major items involved in a typical installation are shown in Figure 23.

PCU 7718 Installation Guide Set Up and Operation Hardware Inputs The 7718 provides eight universal inputs on the base card. These inputs can be defined in the database as analog inputs (AI), discrete inputs (DI), or pulse inputs (PI). Note: Inputs may be defined as AI, DI or PI, but only one type can be defined for a specific point. As the discrete and pulse inputs are scanned, points are tested for a value below or above a 25/75% threshold to determine if the device is an open or closed contact. Closed contact: A value below 25% scale/1.25 VDC (1024 counts) is considered a closed contact. Open contact: A value above 75% scale/3.75 VDC (3072 counts) is considered an open contact. The controller provides an LED indication of the state of points defined as discrete or pulse inputs. When an input contact is sensed as being closed, the software illuminates the respective LED (refer to Input LEDs on page 34). Analog, discrete, or pulse inputs occupy point addresses 0000 through 0007 (see Figure 24). The same point number identifies an input point, regardless of its type.

Set Up and Operation PCU 7718 Installation Guide Power line frequency selection (50/60 Hz) is available through the HHC (refer to Setting the Power Line Frequency on page 10). The 7718 provides a median value filter, as well as a 50/60 Hz notch filter, to reduce/eliminate random electrical noise which normally shows up as extraordinarily high/low readings on the input. Look-Up Tables Selecting Input Type Input LEDs Note: Note: The 7718 PCU allows you to define up to 32 look-up tables, each containing up to 21 points. You may use these look-up tables to create engineering units, create sensor limits, or focus resolution on an interval span of interest that you define. For instance, after you establish the upper and lower limits of the sensor for the look-up table, you can populate the remaining points in the table within a limited area. The area you populate with points can be grouped closely together and provide increased resolution within that span. You may also use the look-up tables to limit the sensor s boundaries within the accuracy range of the sensor, as with a flow sensor. The look-up tables can be used with linear or non-linear sensors, and can be used with integer or non-integer numbers, and unipolar and bipolar entries. Refer to the section on Controller Configuration in any of the following documents for more information: TCON142, TAC I/NET Operator Guide (Windows) TCON207, TAC I/NET 2000 Operator Guide TCON299, TAC I/NET Seven Operator Guide The eight inputs on the base card are shipped in a 0 5 V configuration. The inputs may be configured by placing resistors in the appropriate plug-in positions for each input. The PCU-7718 and its expansion boards must be configured with a plug-in resistor for the following sensors (refer to Installing Resistors on page 19). 2-wire Lini-Temp sensors RTD sensors 0 10 V sensors 0 20 milliampere sensors Dry contact discrete and pulse inputs Connection of 100 ohm RTD sensors to the 7718 baseboard is not recommended. The 7718 has a bank of common LEDs indicating the contact status of the input points. When the discrete/pulse input senses a closed contact, the LED is on. When the point senses an open contact, the LED is off. When a point is defined as an AI, the LED is off at all times. The LEDs correspond to the respective input point. The LEDs are shown in Figure 27 on page 37. The Discrete Output Power LED should illuminate under normal operating conditions. If the LED does not illuminate, fuse F9 (see Figure 23 on page 32 for location) may be blown, and may need to be replaced. 34 2010 Schneider Electric. All rights reserved.
PCU 7718 Installation Guide Set Up and Operation Control Outputs Eight discrete outputs are provided on the base controller. Each output provides a single current sourcing emitter follower circuit capable of controlling up to 0.25 A. These occupy the point address range of 0000 to 0007. External Output Power The 7718 PCU may use an external power supply for the output circuits after you configure jumpers J26 and J27 (refer to Table 8). This power supply may be either 12 24 VDC or AC. When using an external DC power supply, the total output current may be increased to 2 A (0.25 A per output). When using an external AC power supply, the maximum total load is 0.75 A (refer to Connecting External Output Power on page 25). Table 8. 7718 PCU External Output Power Jumper Configuration Function Jumper Configuration External AC/DC Power J26 and J27 jumper A to B Internal Output Power When using internal output power, the maximum total output current is 0.25 A. You must reposition jumper J25 for additional output drive current (refer to Configuring for Unregulated Power on page 25). Discrete Voltage Output Terminals Manual Override Table 9. 7718 PCU Internal Power Selection Function Jumper Configuration Unregulated Internal DC Power J25 jumper B to C Regulated Internal DC Power J25 jumper A to B Internal AC Power J26 and J27 jumper B to C The discrete voltage outputs are terminated via a single nine-position plug-on terminal block (TB6). A common bank of LED indicators contains an LED for each output that is illuminated when the output is energized (see Figure 27 on page 37). Manual override switches (HOA switches) are provided for manual control of each output. In addition, they provide discrete input feedback of the switch status back to the microprocessor (see Figure 25). In the normal (center) position, these switches permit the software to automatically control the devices attached to the outputs. You can manually place a switch in either the On or Off position for maintenance or test purposes. When a switch is in the On or Off position, the software provides an alert indicating that someone has put that point into manual override (see Figure 26). 2010 Schneider Electric.

HOA Switch Positions Note: The switch On/Off position corresponds to the state of the output. The actual state of the controlled environment depends on the field device connected to the output. Analog Output Terminals Two status bits (DI points) are returned from each switch. When in the Auto position, both DI points will indicate an open contact. The 16 feedback status bits on the base card will be mapped into the system on bit offsets 8 and 9 of point address 00 07. (Bit 8 set to 1 indicates Manual On, or energized output. Bit 9 set to 1 indicates Manual Off, or deenergized output.) The first bit in the pair (Bit 8) will indicate a closed contact when the switch is placed in the On position. The second bit (Bit 9) will indicate a closed contact when the switch is placed in the Off position. The analog voltage outputs are accessed through the single, nine-position, plug-on terminal block (TB6). The analog output addresses are 3100 through 3107. When configuring for analog output, you must configure the terminals using jumpers J17 through J24 (see Table 10). Table 10. 7718 PCU Analog Output to TB6 Function Jumper Configuration Analog 0 10 VDC Output to TB6 J17 J24 jumper B to C Note: When any jumper J17 J24 is set to configure one of the output terminals of TB6 as an analog output, the corresponding discrete output is no longer available. The output LED does not reflect the state of an analog output. 36 2010 Schneider Electric. All rights reserved.
PCU 7718 Installation Guide Set Up and Operation Communication Ports Communication LEDs There are three communication ports on the 7718 board, and an optional RS232 communication board that may be added as a plug-on daughterboard. All connections to the LAN, modems, external PCs, and the HHC are made using these ports. See Figure 1 on page 3 for port locations. The two asynchronous serial ports (on the base 7718 board) provide access to external PCs, external modems, and the HHC. The RS485 port provides a connection for the TAC I/NET controller LAN, while the RS232 serial port allows connection to a modem or direct connection to a TAC I/NET host PC. Refer to Installation Procedures on page 10 for instructions on connecting each of these communication ports. The 7718 provides a bank of ten LEDs (see Figure 27) that show the status of communication in the controller, along with other information.

RS232 Port The first asynchronous port (P4) provides a 9-conductor D-Sub miniature RS232 interface for direct connection to a TAC I/NET host PC or external auto-answer (i.e., Integrated Dial) Hayes-compatible modem. Use a standard TAC HHC connected to the 7718 to set the baud rate for port P4 (refer to Setting the Tap Baud Rate on page 11). When the 7718 is connected directly to a PC, it performs the functions of a 7801 Tap without consuming a second LAN address. When connected to a Hayes-compatible modem, the Integrated Dial function (i.e. one-way dial from the host PC to the controller LAN) is provided. Port P4 provides the circuit connections typical of the serial COM port on the PC. Use cable number CBL072 for DB-9, and CBL073 for DB-25 connections to PC COM ports. 38 2010 Schneider Electric.

PCU 7718 Installation Guide Set Up and Operation Use cable number CBL074 to connect the 7718 to a modem using a 25-pin connector. The RS232 Expansion Module may be used simultaneously with the 7718 directly connected to a PC. Hand Held Console Port RS485 LAN Port The second asynchronous port (P1) provides a modular TTL level interface to the standard HHC and operates at 1200 baud. An RJ11 modular jack is provided along the lower left side of the controller for connection of the TAC HHC. The HHC is used to field check the PCU, and to set the LAN address and baud rate of the 7718 PCU before connecting it to the TAC I/NET controller LAN. The RS485 LAN port (TB3) is accessed via a three-position terminal block located along the left edge of the 7718 PCB (see Figure 28). This port provides a communication pathway to the TAC I/NET controller LAN. When connected through this port, the 7718 can communicate with up to 63 other controllers or Taps on the same controller LAN. It may also communicate with controllers on other controller LANs through a Host/Link Tap. TB2 RS485 LAN Port J31 TB3 P1 Figure 28.

Set Up and Operation PCU 7718 Installation Guide Protocol LAN Node Address Data Rate Expansion Ports The RS485 LAN port uses SDLC protocol and implements a token-passing bus to regulate access to the controller LAN. The controller LAN can accommodate up to 64 nodes. The 7718 controls the RS485 LAN port through an SDLC Serial Communication Controller located on the processor chip. The LAN node address (0 63) of the controller is selected using a HHC. Refer to TCON073, HHC Hand Held Console User Guide, for operating details of the HHC. The data rate for the RS485 SDLC LAN port on the base card is selectable from the HHC with the current selection maintained in nonvolatile storage. The rate selection supports selection of 9,600 or 19,200 using the on-chip baud generator. The normal rate is 19,200 baud. In addition to the eight inputs and eight outputs on the base card, the 7718 supports the control of eight additional outputs and the monitoring of up to sixteen additional AI, DI, and PI inputs connected via the expansion port. These inputs and outputs occupy point addresses 0100 through 0107 (outputs) and 0100 through 0207 (inputs). For additional information, refer to the Expansion Modules below. I/O Expansion Port All I/O Expansion Boards, except the RS232 serial option, attach to port P3 at the lower end of the controller PCB (see Figure 29). The expansion port creates a general purpose interface to the 7718 s microprocessor bus. This port provides the flexibility to address I/O point quantities and types which are not commonly required or justified for inclusion on the base unit. P1 P2 TB4 J25 P3 Figure 29.

PCU 7718 Installation Guide Set Up and Operation Discrete Outputs Whether used as PWM outputs or discrete outputs, the output point addresses are 0100 through 0107. Outputs may be defined as either PWM or discrete. Each output point address on the expansion module corresponds with a numbered terminal on a terminal block TBX3. The output terminals are located on a 9-pin connector at TBX3. The outputs are numbered 1 through 8; the ninth pin is the output common (typically earth ground). Each output provides a single current sourcing emitter follower circuit capable of controlling up to 0.25 A. A common bank of LEDs illuminate, indicating the state of the output circuits. The LEDs are numbered DO-8 from the top, to DO-1. The bottom LED is labeled OPWR, for output power, and illuminates when power is present on the discrete output circuits (see Figure 31). Note: This LED should illuminate under normal operating conditions. If the LED does not illuminate, fuse F1 on the E8UI8DO Expansion Board (see Figure 30 on page 41 for location) may be blown, and may need to be replaced. Power E16UI Expansion Module Universal Inputs The E8UI8DO Expansion Board can either use a separate power supply or the same power supply that the 7718 uses. It can further use AC or DC power. You may also use unregulated DC power from the on-board supply to increase the total output current capacity to 0.75 A. The external AC power carries this same 0.75 A total, while external DC can be used to boost total output current to 2 A (0.25 A on each of the eight outputs). The E16UI expansion module (see Figure 32) supports the monitoring of an additional 16 input points, bringing the total number of points for the base unit and an expansion module to 32. These points can be used for: analog inputs discrete inputs pulse inputs The expansion module card is 3.4" L 8.6" W (8.8 21.8 cm). It attaches on top of the 7718, and is secured to the baseboard with the supplied standoffs and screws. A ribbon cable attaches the expansion module s P1 port to the baseboard s P3 port. The inputs are located on TBX1, TBX2, TBX3 and TBX4. The inputs are grouped in sets of three terminals for each input.

Set Up and Operation PCU 7718 Installation Guide TXD RXD DCD RS232 Port P1 P2 Figure 34. RS232 Serial Interface Board This interface supports user-selected data rates up to 9600 baud. This optional interface can be connected to: External auto-dial/auto-answer (AD/AA) modem When connected to a Hayescompatible AD/AA modem, the 7718 will provide the functionality of the 78061 Tap. This following types of modems are supported: Synchronous Use a synchronous modem when the controller is loaded with a TAC I/NET version 4.x or earlier binary file. The controller must also have TAC I/NET version 4.x boot firmware (EPROM). Asynchronous Use an asynchronous modem when the controller is loaded with a TAC I/NET 2000 or later binary file. The controller must also have TAC I/NET 2000 or later boot firmware (EPROM). Note: Ensure that all AD/AA Taps within your TAC I/NET system are configured to use the same communication protocol either synchronous, or asynchronous. Mixing AD/AA protocols will cause communication errors. TAC I/NET 2000 is compatible with TAC I/NET version 4.x Tap and controller binary loads. Therefore, when synchronous AD/AA communication is required on TAC I/NET 2000 system (for example, when using a 78040, 78050, or 78060 Tap), you must continue to use TAC I/NET version 4.x Tap and controller binary loads. Use cable number CBL048 for connecting to either of these modems. Refer to the TAC I/NET Technical Reference Guide for more AD/AA information. External synchronous dedicated line modem When connected to an external Hayes-compatible dedicated line modem, the 7718 provides the functionality of a TAC 78035 Tap. Use cable number CBL048 for this connection. Refer to TCON101, TAC I/NET Tap and Repeater Installation Guide, for a complete description the 78035 Tap function.

PCU 7718 Installation Guide Set Up and Operation Tap Emulation and Modem Setup The 7718 controller can be configured to emulate several types of TAC Taps, as follows: 7801 Host Tap Using this emulated Tap, you can connect the following devices directly to the 7718 controller at port P4: Host Workstation This connection supports the Direct-connect function of the 7801 host Tap. Asynchronous Hayes-compatible Modem When the modem is configured to auto-answer incoming calls, this connection supports the Integrated Dial function of the 7801 host Tap. This configuration allows you to use voicegrade phone lines to communicate with the controller LAN from a remote PC. 78035 Site (LAN) Tap This emulated Tap requires the use of an optional RS232 expansion module. Using this Tap function, you can connect a synchronous dedicated-line (i.e., leased-line) modem to port P2 of the RS232 expansion module. 78061 Dial Site (LAN) Tap This emulated Tap requires the use of an optional RS232 expansion module. Using this Tap function, you can connect a Hayescompatible modem to port P2 of the RS232 expansion module. You may then configure the modem for auto-dial/auto-answer (AD/AA) operation (refer to Modem Switch Settings on page 49). Note: When using the emulated 78061 Tap function, the controller s binary load (i.e., *.BIN file) determines whether a synchronous or an asynchronous modem will be required for AD/AA communication. For a TAC I/NET 2000 or later binary load, the modem must be capable of asynchronous communication. For a TAC I/NET revision 4.x or earlier binary load, the modem must be capable of synchronous communication. Refer to the communication chapter in the TAC I/NET Technical Reference Guide for more information about AD/AA communication. Ensure that all AD/AA Taps within your TAC I/NET system are configured to use the same communication protocol either synchronous, or asynchronous. Mixing AD/AA protocols will cause communication errors. 78061 Tap Emulation and Beeper Operation Beeper calls are used to notify a user of a specific condition occurring in the TAC I/NET system. This condition is user-definable using message masking and priorities. The beeper is only a notification tool. It contains no originating code or phone number. It issues either a tone or vibrates the beeper. To specify a beeper call, select Beeper in the Type field of the 7806 Configuration editor. If a beeper service is used, enter the beeper service phone number. If a human response is expected, enter an @ symbol at the end of the beeper number. This will allow the 78061 Tap emulation to retry on busy and noanswer conditions. The @ symbol will cause the modem to listen for a 5-second period of silence after the first ring is detected. The length of time that the modem will listen for this period of silence is established by the Timeout field in the editor. If a period of silence is detected, the call will be considered complete. 2010 Schneider Electric. All rights reserved. 47
Set Up and Operation PCU 7718 Installation Guide Note: Some experimentation with the timeout period that is set in the Tap editor may be required. This timeout period should be set long enough to cause the modem to hang on the line until the 5-second period of silence can be detected. Since this beeper function is used internationally to dial out to numbers that must have a human response, it is necessary to accommodate differences in the manner in which beeper systems and humans respond. When using an external modem (78061 Tap emulation) you should initialize your Hayes-compatible modem with the X4 command (factory default), which enables your modem to return the busy response code if it is expected that a person will answer (or not answer) the telephone. This will provide a rapid response to a busy error. Note: It is imperative that any modem used for beeper interfacing operate as described above. The 78061 emulation will alter the modem initialization timing sequence to always initialize at a 2400 baud data rate. Note: The 7718 PCU will send a setup string to the modem to place it in the auto-answer mode. This auto-answer function will be set to answer on the first ring. 78061 Tap Emulation and Pager Operation Select pager operation in the TAC I/NET software by selecting Beeper from the Type field. Pager operation is used to notify a user of a specific condition occurring in the TAC I/NET system. This condition is user-definable using message masking and priorities. The pager is designed to receive a string of characters that are displayed on the recipient s pager. This string could represent a phone number or a recognizable warning code. You may call a pager using the 78061 Tap emulation. The current version of TAC I/NET adds several additional phone number characters for use with dial strings. Table 16 shows the additional characters and their definitions. Table 16. Pager Character Definition Pager Character Definition @ Waits for five seconds, replaces the need for numerous commas. Causes an immediate hang up, and should be used at the end of every ; digital pager number dialed. (Not for use with a beeper.)! Issues a Hook flash, forcing the phone to go on-hook for 0.5 seconds. W A pager differs from a beeper in that the pager sends a string of characters after a 5- second period of silence. Also, beepers never use the semi-colon in their call string, while digital pagers always require the semi-colon at the end of their call string. It is important that you be familiar with your pager service and phone system so that you know of any specific characters that may be required to place a successful call. For example, if you were to enter a phone number for SWB MobileComm pagers in a 78061 Tap emulation, using an ITT System 3100 PBX you would use the following format. T9W8172731511#@123456; Wait for a dial tone. 48 2010 Schneider Electric. All rights reserved.
PCU 7718 Installation Guide Set Up and Operation The T at the beginning of the character string initiates tone dialing, the 9 obtains an outside line. The W causes the Tap to wait for the modem to receive a dial tone before dialing the pager service phone number. At the end of the phone number is a # sign that causes this PBX to perform speed dialing, eliminating any unwanted delays. The @ character causes the 78061 Tap emulation to wait five seconds and then sends the code that will display on the recipient s pager. The semi-colon causes the Tap to signal the modem to immediately go on-hook, ending the call. If your telephone system has no speed dial function, but has a period of silence exceeding five seconds before the connection is made, add additional @ characters or commas to prevent the Tap prematurely sending the pager code. If the number being dialed is really a pager system (particularly a digital pager system), the modem should be initialized with an X2 command. This will cause the modem to ignore at least some of the tones presented by the digital pager system (that may be interpreted as busy) when the call is successful. Note: Some experimentation may be required to find the proper combination of characters to make the pager call successful. Modem Switch Settings Auto-dial/Auto-answer The 7801 Integrated Dial and 78061 AD/AA emulated Tap functions require the use of external modems. You must configure these modems for proper communication. For modems without hardware switch settings (i.e., with software-controlled switch settings only), a terminal emulator, such as Procom, or the communication software received with your modem, must be used to issue command strings to the modem for proper initialization. The modem setup requirements are described in the following paragraphs. Note: When using the emulated 78061 Tap function, the controller s binary load (i.e., *.BIN file) determines whether a synchronous or an asynchronous modem will be required for AD/AA communication. For TAC I/NET 2000 or later binary load, the modem must be capable of asynchronous communication. For a TAC I/NET revision 4.x or earlier binary load, the modem must be capable of synchronous communication. Refer to the communication chapter in the TAC I/NET Technical Reference Guide for more information about AD/AA communication. Ensure that all AD/AA Taps within your TAC I/NET system are configured to use the same communication protocol either synchronous, or asynchronous. Mixing AD/AA protocols will cause communication errors. The optional RS232 expansion module (port P2) can be used as an interface for an external Hayes-compatible auto-dial/auto-answer (AD/AA) modem. This configuration is supported when the 7718 is set to emulate a 78061 site (LAN) Tap. Issue the following settings to your Hayes-compatible modem from a terminal emulator. 1. AT &F 2.
