GE FANUC IC697MEM735B 32-BIT CMOS EXPANSION MEMORY BOARD VER. 512KBytes / 90-70

Description

GE FANUC IC697MEM735B 32-BIT CMOS EXPANSION MEMORY BOARD VER. 512KBytes / SERIES 90-70. Condition is Used. S/N:02853540 and S/N: 03771703 ( 2-BOARDS ) ASM. NO. 44A729681-GO2 / FAB.NO. 44A729682-002R03/3   002/3
Features:
- 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.
- 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.
