Functions The CPU 788 is a single slot programmable controller CPU which is programmed and configured by MS-DOS or Windows based programming software for use in Emergency Shut-Down (ESD), fire and gas, and other critical control applications. It communicates with I/O and smart option modules over the rack mounted backplane (IC697CHS750, 782, 783, 790, 791) by way of the VME C.1 Standard format. The CPU 788 must be used in conjunction with a set of C program blocks which provide Triple Modular Redundancy (TMR) operating and autotest routines. It will not operate unless these program blocks are included in the loaded application program. For detailed information on TMR systems, see Reference 4, the IC660/661 Modular Redundancy Flexible Triple Modular Redundant (TMR) System User s Manual.

Typical GMR System Configuration User Memory Program and data memory for the CPU 788 is available by attaching an expansion memory board with 512 Kbytes battery-backed CMOS RAM. Up to approximately 200 Kbytes of this memory is available for the user application program and data. Operation, Protection, and Module Status Operation of this module may be controlled by the three-position RUN/STOP switch or remotely by an attached programmer and programming software. Program and configuration data can be locked through software passwords or manually by the memory protect keyswitch. When the key is in the protected position, program and configuration data can only be changed by a programmer connected parallel only (i.e., via the Bus Transmitter module). The status of a CPU is indicated by the four green LEDs on the front of the module. Installation It is the responsibility of the OEM, system integrator, or end user to properly install the PLC equipment for safe and reliable operation. Product manuals provide detailed information about installation, startup, and proper use of the PLC equipment. The installation manual, shipped with your PLC programming software, describes how to properly install the equipment. If the PLC installation must comply with supported standards, such as FCC or CE Directives, please refer to the Installation Requirements for Conformance to Standards, shipped with the PLC programming software, for additional guidelines. Installation should not be attempted without referring to the applicable programmable controller hardware installation manual. Align the expansion memory and CPU connectors. Align the captive screws on the memory board with the standoffs already installed on the CPU. Push the memory board onto the CPU connector ensuring the mating screws remain aligned with their respective standoff. Screw each memory board screw into the standoffs with a #1 Phillips screwdriver, firmly tighten each. Connect the battery to either of the battery connectors on the module. Put toggle switch in the STOP position. Put keyswitch in Memory Protection OFF position. Make sure rack power is off. Install in slot 1 of rack 0. Turn on power. 3 16 MHz, 32-Bit Expandable Central Processing Unit for IC66* Triple Modular Redundancy Systems GFK-0806D PLC CPUs August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 25-3 The module should power up and blink the top LED. When the diagnostics have completed successfully, the top LED stays on and the second and third LEDs are off. The fourth LED is off if the keyswitch is in the OFF position. The CPU is now ready to be programmed (if connected parallel, the CPU can be programmed regardless of key position). After the program has been verified the toggle switch may be moved to the appropriate operation mode position. The LEDs indicate the position of the toggle switch, memory protection status, and the state of the program. Expansion Memory The CPU 788 must have a CMOS RAM expansion memory board. The CMOS expansion memory board provides CMOS RAM memory of 512 Kbytes. Up to approximately 200 Kbytes of this memory is available for the user application program and data. The battery which supports this memory is located on the main CPU board housing. Installation of a CMOS expansion memory board on the CPU will require initialization of the CPU with the programmer (See Reference 2). Programmer Connection, Parallel For a parallel interface (MS-DOS programmer only) the programmer is connected to the top port on the Bus Transmitter Module (IC697BEM713). Consult Reference 1 for a description of programming functions.
