12 ! R S23 2 TE RMIN AL XXX.XXX.XXX.XX IP ADDRESS User Guide 2.0 SYSTEM OVERVIEW The Landscan LSP Processor provides a dedicated data input, mathematical processing facility for use with LANDSCAN sensor heads for process control applications. The processor provides external communications interfaces for system configuration and for the transmission of scan line information to host computers. This can be achieved using RS232C or an Ethernet connection when the transmission of large quantities of data at high speed is required. The processor has been designed to function automatically and continuously with in-built self-analysis of system events, plus comprehensive diagnostic information accessible through the configuration software and front panel display. The processor supports up to two simultaneous Ethernet connections. In addition, the processor captures data from any of the Landscan heads and manipulates the information into a zone model. The system can be considered to consist of two distinct components, the Control Processor and the Configuration Software which runs on a portable PC and is used to configure the processor parameters. PROCESS MONITORING PROCESS CONTROL Optional Software Landscan NT Ethernet Ethernet Switch RS232 Serial Comms LSP SYSTEM Interconnection Cable Temporary Link Portable PC RS232 LSP Linescanning Thermometer LSP Processor Configuration Software Fig. 1 - Typical LSP System Overview Page 2

13 2.1 LSP Processor The LSP Processor is a wall mounted unit, that will sample 1000 data points per scan line, at scan speeds between 10Hz and 100Hz. The processor can partition the scanner temperature profile into a maximum of 14 discrete regions or zones which can overlap if required. Within these zones a processing function can be applied to yield peak, average and minimum measurements. An analog 4 to 20mA output is provided that allows for remote control of the Landscan sensor head's emissivity settings. An additional alarm relay output is available to alert the user to conditions which may result in the data captured being invalid. (e.g. power loss at the Landscan sensor head) The product edges can be detected by identifying where in the scan line the temperature rises above a preset threshold level. This is achieved automatically by analysing the peak product temperature in relation to the environmental background temperature. The system uses the edge detection information to align the zone positions, allowing the zones to track a target which may be moving erratically within the sensor s field of view. If the target moves, grows or shrinks within the sensor s field of view, the zone model follows these movements. The processor provides an RS232 serial communication connection located on the front panel, which allows a laptop personal computer or similar to be connected temporarily to allow modifications to the system configuration. A second RS232 serial communications connection can be used for permanent monitoring. Ethernet communication is also provided on the processor to allow the connection of third party computer systems and also the Landscan NT software. Calibrated temperature data and zone processed data are available in real time for the purposes of analysis and database storage by remote computer systems. Configuration of the processor is fully supported by the Ethernet communications, with the configuration software capable of setting up the processor for an appropriate network setting. When the user has satisfactorily configured the system for a particular application, the parameters essential for operation are secured against power loss inside the system. The processor will continuously operate without interruption, utilising these settings until parameter changes are requested by the user. 2.2 Configuration Software The Configuration Software enables the user to communicate with the processor for initial setting up of the operating parameters and provides limited process monitoring capability. All operating parameters are securely retained in the non-volatile memory of the processor. The Configuration Software features; Configuration of: Scanner Type Processor Ethernet Zones and Alarms Displays: Profile Zone and Alarm Status Scanner Status Zone Profile (Professional version only) 2D Map (Professional version only) Configuration Load and Save Processor Diagnostics Context Help Temporary communications are through an RS232 terminal on the front panel of the processor. Permanent process monitoring may be achieved via a second RS232 link to the processor base panel connection. For further information, see the LSP Configuration Software User Guide. Page 3

17 4.3 Mains Power (X1) The processor requires a three-wire a.c.supply, that includes an earth ground connection. Warning RISK OF ELECTRIC SHOCK The a.c. supply and associated wiring must conform to local regulations for voltage and power rating. Failure to provide an earth ground connection can cause electric shock and improper operation of the equipment. Ensure that the earth ground wire has a current carrying capacity equal to, or greater than the largest power conductor. Ensure that the a.c. supply to this equipment is connected through an accessible isolator switch. The power consumption of the LSP Processor is approximately 60W and the unit must be fused independently with a 5amp fuse.

The user is able to request live data and remotely configure the processor from the user's own PC. To make use of the external communications, customers must send commands to the processor using the LAND specified format. Full details of the LAND messaging interface are given in the Processor Configuration Software User Guide. The processor provides a connection for a 10BASE-T RJ45 Shielded Twisted Pair (STP) connector of CAT5 specification. The general cable recommendation is to use shielded 10BASE-T LSOH Category 5 / Level 5 STP cable.this provides protection from electromagnetic interference in industrial environments. The use of unshielded 10BASE-T LSOH Category 5 / Level 5 UTP is only recommended for area's that are guaranteed to be free from severe electromagnetic interference. The maximum cable length allowed is 100m / 328ft, which can be extended to 457m / 1499ft by utilising external network repeaters. X Fig Ethernet Connection Page 9

20 4.10 External Communications - Serial RS232 (X8) The serial connection provides the means by which a user can request statistical data and remotely configure the processor from the user's own PC. To make use of the external communications, customers must send commands to the processor using the LAND specified format. Full details of the LAND messaging interface are given in the Processor Configuration Software User Guide. The general recommendation for cable is 3-core with overall screen.

Page 11

22 5.2 System Display Events The display is also used to indicate various software events. These events override the usual functions of the indicators allowing the user to confirm events performed by the software. The following events are indicated: Start-up Progress - On power-up, the unit runs through a sequence of the LED's to indicate the stage of the unit start-up procedure. Each LED is switched on at various stages to indicate progress. The sequence used is: Power System Running Ethernet Comms Scanner Temperature Alarm System Alarm Following this sequence, the unit beeps to indicate a successful start-up and the 'System Running' LED starts to flash. (Refer to Appendix B for 'Start-up Mode Diagnostics Chart', detailing information about each stage of progress) System Exit to Flash Upgrade Mode - If an LSP Processor is connected to a laptop using the serial port and a request is received to enter the Flash Upgrade Mode, the LED's run through the start-up sequence once, to indicate that the software is entering Upgrade Mode.

23 6.0 ETHERNET CONFIGURATION The Ethernet network is configured using the Ethernet ID switch located on the processor front panel. 9 XXX.XXX.XXX.XX IP ADDRESS Fig Ethernet ID Switch The rotating switch on the front panel allows the user to set a unique number for each unit. This number is the lowest digit of the IP address stored in the unit. XXX.XXX.XXX.XX_ On power-up, the unit then reads the switch and creates the unit's IP address from the base address plus the switch setting. For example, if the base address of the unit was and the switch setting was 5 the actual IP address used by the unit would be This allows for all units on the network to be configured with the same base address and have a unique switch setting. Using this system allows units to be moved around the network without the need to use configuration software to change network settings. The base address of the unit can be changed using the Configuration Software, details of which are explained in the Configuration Software 'User Guide'. Note The switch is only read on power-up of the unit and any changes to the switch position following this, does not change the network IP address. It is therefore necessary when applying power to the unit, to ensure that the IP switch setting is in the relevant position. Page 13
