The GE Fanuc is used to expand the memory of the GE 772 and 771 cpus in the GE PLC. Memory modules can be used to expand PCM memory reserved by the battery on the CPU or PCM, and do not require any additional slots that can be configured for data and program storage. The IC697MEM717 memory module has different storage capacities. Different storage capacity options include 64, 128, 256, and 512 KB of memory space. The IC697MEM717 memory module can be installed as a daughter board when it is located in the same slot as the module it serves. The memory on the board supplements the memory available on the base board. The IC697MEM717 memory module ensures memory retention in the event of a power failure of the battery on the substrate housing.
The IC697MEM717 memory module comes with a logic program memory that is constantly checked by the PLC CPU as a background task. PCM error checking of the stored memory continues when the power is restarted and during hard and soft resets. For CPU installations, technicians should use Windows programming software or use MS-DOS software to clean memory. For PCM installations, technicians should follow all instructions provided by the programmable coprocessor module. The IC697MEM717 memory module has a shelf life of 10 years at an optimal ambient temperature of 20 degrees Celsius (equivalent to 68 degrees Fahrenheit). The module has a nominal memory retention time of 6 months without power being applied. The battery ensures that user memory is retained even in the event of a power outage, and keeps the calendar clock running and accurate even in the event of a power outage.
