GE / IP FANUC Series 90/30 In Stock
The IC697MEM732 is a 32-Bit CMOS Expansion Memory by GE Fanuc for Series 90-70. It delivers 256 Kbytes of non-volatile flash memory and provides logic and data memory for PCU modules 780, 781, 782, 788, and 789. This board is required for proper operation of these CPUs since the baseboard holds no RAM memory. IC697MEM732 is installed as a daughter board and is situated in the same slot as the module it serves. An additional slot is not required. IC697MEM732 has several features, notably its availability in 128 KB, 256 KBs with 256 KB of non-volatile flash memory, 256 Kbytes, and 512 Kbytes options. It is configurable for both data and program storage. If power is lost, memory is automatically saved by a lithium battery C697ACC701 placed on the baseboard’s housing.
In addition to maintaining user memory if power is removed, the battery operates a calendar clock on the PLC CPU. Remember to always install a new battery before beginning removal of the old one to avoid potential issues. Conveniently, flash memory is retained if power were to be loss without the need for battery connection. Logic program memory is automatically error-checked by the PLC CPU as a background task. Installation of memory expansion IC697MEM732 is straightforward and can easily be installed in the field. The only tool needed is a Phillips screwdriver #1. Simply screw each expansion board screw into the standoffs, tightening firmly. Rack power should be OFF before installing the CPU module. Then the module can be placed in the rack.
