The high-performance CPM790 CPU, which supports 2048 TMR , is based on a 64 MHz 80486DX2 microprocessor and includes a 1-megabyte memory daughterboard.. The model 788 CPU supports approximately 100 TMR and the model 789 CPU supports approximately 2048 TMR . Both the 788 and 789 have a 16 Mhz 80386DX microprocessor and occupy one slot in the CPU rack (with memory daughterboard attached). Software configuration of the CPUs is done using the LM90-70 programming and configuration software--no switches or jumpers are used. These CPUs execute both the GMR system software and the application program logic. Application program logic is typically written in ladder logic form, but Sequential Function Chart (SFC) programming and “C” programming capabilities also exist. These CPUs along with the GMR system software perform the following functions: n User application program execution n Inter-CPU communications n Majority voting of all inputs n Input and output autotesting n Input and output discrepancy checking n General system diagnostics n Fault reporting The CPM790 CPU module includes 1 megabyte of memory. Approximately 512K bytes of this memory is available for the application program. The CPU 788 and 789 modules require a 512K-byte memory daughterboard. Approximately 200K bytes of this memory is available for the application program. This CMOS RAM is battery-backed by a lithium battery on each CPU module. The battery can retain memory contents for up to six months. The battery has a life of at least ten years. The module has two battery connectors so a replacement battery can be added before a “low” battery is disconnected. A low battery, dead battery and missing battery are all diagnosed and alarmed by the CPU. Each of up to three CPUs in a system operates entirely independent from each other CPU. The CPUs exchange general status information, autotesting and fault information, program checksum and configuration data checksum information and optionally user application data via a built–in global data facility. This information and data is exchanged between the physically-isolated CPUs over the same Genius buses that are already present to interface to modules. Extensive CPU module and memory diagnostics are performed both at powerup and continuously by each CPU. Faults are logged in a PLC fault table which can be viewed with the Logicmaster programming and configuration software. The other CPUs are made aware of any individual CPU faults by reading status information. Each CPU has a built-in RS-422/RS-485 serial port which is typically used for a multi-drop connection to the programming and configuration system. It can also be used for connection to a host system or operator interface. A three–position toggle switch can be used select Run Mode or Stop mode. A Memory Protect prevents accidental program changes (passwords can also be used). Four status LEDs (all normally on) show the CPU’s status: n “OK” LED – CPU diagnostic tests executed successfully (no faults). n “RUN” LED – CPU is in Run mode and executing application program. n “ENABLED” LED –CPU has enabled outputs to turn on/off as set in the application program n “MEM PROTECT” LED – Memory Protect keyswitch is on. a46612 OK RUN ENABLED MEM PROTECT CENTRAL PROCESSOR UNIT Y R E B A T T CPU Module with Door Open and with Door Closed LEDs Dual Battery Connectors RS-485 Serial Port Mode Selection Switch 4-12 Genius® Modular Redundancy Flexible Triple Modular Redundant (TMR) System GFT-177A Technical Product Overview – February 1998 4 CPU Module Specifications MODEL # (IC697) CPU788 CPU789 CPM790 Max. fully triplicated TMR Digital Inputs 112 2048 2048 Max. fully triplicated TMR Digital Outputs 80 2048 2048 Max. fully triplicated TMR Digital (Combined I&O) 112 4096 4096 Max.
