Product Manual Excerpt

Features Available in 128 KBytes, 256 KBytes w/256 KBytes non-volatile flash memory, 256 KBytes and 512 Kbytes. For expansion of CPU 780/781/782/788/789. Memory retained by battery on CPU. Does not require additional slot. Configurable for data and program storage. Error checking by CPU checksum routine. Installation requires only a #1 Phillips screwdriver. Field Installable. Parity generation and checking for each byte of SRAM. Functions CMOS Expansion Memory is available in four versions; 128 KBytes, 256 KBytes w/256 KBytes non-volatile flash memory, 256 KBytes and 512 Kbytes. This memory must be used to provide logic and data memory in the PLC CPU 780/781/782/788/789 Central Processor Unit modules. It is installed as a daughter board and resides in the same slot as the module it serves. This board is required for proper operation of these CPUs since the base board contains no RAM memory. Memory is retained in the event of power loss by the battery on the base board housing. Flash memory is retained in the event of a power loss with or without the battery connected. Logic program memory is continually error-checked by the PLC CPU as a background task. Memory parity errors are reported to the PLC CPU when they occur. a44437 Figure 1.

Align the expansion memory board and CPU connectors. Align the captive screws on the expansion memory board with the standoffs already installed on the CPU. Push the expansion memory board onto the CPU connector ensuring that the mating screws remain aligned with their respective standoff. Screw each expansion memory board screw into the standoffs with a #1 Phillips screwdriver, firmly tightening each screw. Make sure rack power is off before installing the CPU module. Place module in rack. Turn power on. Clear memory with MS-DOS or Windows programming software following instructions in the Programming Software User s Manual (Refer to Reference 1). Batteries The Lithium battery (IC697ACC701) is installed as shown in Figure 2. This battery maintains user memory when power is removed and operates the calendar clock on the PLC CPU. Be sure to install the new battery before removing the old battery. Specific indication of a low battery state is detailed in References 3, 4 and 5.
