Ge Fanuc IC697MEM715 , CMOS Expansion Memory Manufactured , Series 90-70

Product Description

IC697MEM715 is a CMOS expansion memory manufactured by GE Automation and Controls. IC697MEM715 is available in different versions: 64 KB, 128 KB, 256 KB, and 512 KB. Typically these memories are used to expand the data and logic memory in CPU 772/771 modules or in the programmable co-processor module (alternatively known as IC697PCM711). IC697MEM715 is configurable for both data and program storage.

IC697MEM715 is configured as a daughter board and is placed in the same slot as the module in which it operates. Memory of the base board and the daughter board are supplementary. In the event of power loss, memory is retained by the battery on the base board housing. Logic program memory is repeatedly error-checked by the PLC CPU as a background task by way of checksum routine. When power is cycled and during hard or soft resets, the PCM error automatically checks storage memory. IC697MEM715 does not require an additional slot for configuration, and it is adjustable for storage of the program and data.

IC697MEM715 uses MS-DOS or Windows programming as software for configuration. IC697MEM715 includes a lithium battery, which manages a calendar clock. In case of power failure, the lithium battery also retains the user memory. Battery shelf life is 10 years with an operating temperature of 20 0C or 68 0F. The ideal memory retention capacity of the battery is six months. Removal of the old battery should not occur unless installation of the new battery is complete. IC697MEM715 requires no tools required for installation and is field installable.

About IC697MEM715

The IC697MEM715 memory module from GE Fanuc is available in 64 KB, 128 KB, 256 KB, and 512 KB capacities. The GE CMOS expansion memory module like this one are used for data expansion and for expanding the logic memory in GE 771/772 CPUs in PLCs. The modules are also used in the programmable co-processor modules in PLCs. The IC697MEM715 module is configurable for data as well as for program storage and it is configured as a daughterboard when it is placed in the same slot as the module in which it operates. The memory of the base and the daughterboard are supplemental and in the event of a power loss, the battery on the base housing will retain the memory. The logic program memory repeatedly checks for errors through the checksum routine. When the power is cycled and also during the soft reset or hard resets, the PMC error will check the storage memory automatically.

The IC697MEM715 memory module is built to function without requiring an additional slot for configuration. Moreover, it is adjustable for the storage of programs as well as for the storage of data. When it comes to programming on the Windows operating system, the IC697MEM715 memory module uses the MS-DOS software as the configuration software. It comes with a lithium battery that backs up the calendar clock. Therefore, in case of a power failure, the lithium battery still retains user memory. The battery shelf life is up to 10 years. The IC697MEM715 memory module operates well at an average ambient temperature of 20 degrees Celsius or 68 degrees Fahrenheit. It has a memory retention capacity of 6 months without applied power.
