9 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

Refer to TCON101, TAC I/NET Tap and Repeater Installation Guide, for a description of the Direct-connect and Integrated Dial functions of the 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 Schneider Electric. All rights reserved.

12 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 ( 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 Schneider Electric. All rights reserved.

13 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 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 Schneider Electric.

14 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 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 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 Schneider Electric. All rights reserved.

15 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 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 Tap, it can store the telephone numbers a standard 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, and 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.

16 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 ( 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 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 ( 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 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 or 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 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 Schneider Electric. All rights reserved.

17 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 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 Tap. Refer to TCON101, TAC I/NET Tap and Repeater Installation Guide, for a complete description the Tap function. Another RS232 data communication device Schneider Electric. All rights reserved. 9

On the E16UI Expansion Board, jumper the J10 center pin to +5 V for TBX1 and TBX2, and jumper the J12 center pin to +5 V for TBX3 and TBX4, to provide the +5 V pull-up. 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. To achieve +15 volts, position the jumper on posts A B of the respective jumper. Position the jumper on posts B C of the respective jumper for +24 volts. Jumpers J9 and J11 select the voltage for sensor excitation. Jumpers J10 and J12 select the setting for pull-up voltage (+15 V or +5 V) through B resistor strips. Table 6.

Input Configuration Resistors The A positions provide a pull-down to DC ground on the input signal for analog input current sensing. The B positions provide a pull-up on the input to 5 volts DC for excitation of discrete contact inputs. The B position also is also used to excite an RTD sensor configured in 2-wire mode. The C positions provide a resistance divider for achieving a 0 10 V input span.
