Ge Fanuc Ic697mem719 , 512 Kb Cmos Expansion Memory Produced , Series 90-70

Product Description

The IC697MEM719 is a 512 KB CMOS Expansion Memory produced by GE Fanuc for the Series 90-70. This memory is used to expand logic and data memory in IC697CPU771/2 Central Processing Units or the Programmable Co-Processor Module (PCM) catalogued IC697PCM711. The IC697MEM719 has a number of notable features including its availability in four versions (64, 128, 256, and 512 Kbytes), its ability to be configured for both data and program storage, and the fact that it does not require any extra slot. Configured as a daughter board, IC697MEM719 is strategically placed in the same slot as the module in which it operates. It is important to note that the memory of the baseboard and that of the daughter board supplement each other.

The IC697MEM719 has a lithium battery that retains user memory in case of power failure. The battery also takes care of the calendar clock. Battery shelf life is 10 years in appropriate conditions, and its operating temperature range should be around 20 0C or 68 0F. The ideal memory retention capacity of the battery without applied power is six months. The old battery should only be removed after complete installation of a new battery. The PLC CPU repeatedly error checks the logic program memory as a background task by way of checksum routine. Storage memory, on the other hand, is error checked by the PCM when power is cycled and on hard/soft system resets. The IC697MEM719 uses MS-DOS or Windows programming as software for configuration. This memory expansion requires no tools and can be easily installed in the field.

About IC697MEM719

The GE Fanuc IC697MEM719 CMOS memory module is available in either 64, 128, 256, or 512 KB of memory capacity and it is commonly used on the GE 771 CPUs, the GE 772 CPUs, or the PCMs. The IC697MEM719 expansion memory module can be used on the PCM or CPU and it does not require the use of additional slot configurations for either data storage or for program storage. The memory can be used for the expansion of logic and data memory when it is installed as the daughterboard in the system and resides in the same slot as the module that it serves. The IC697MEM719 memory module has the ability to retain information in its memory even in the event of power loss. This is made possible through the built-in memory that is on the baseboard housing. Moreover, the logic program memory is checked for errors continually by the PLC, the CPU, or as a background task. The PCM error checks the storage memory whenever the power cycles in the case of a hard or a soft resetting.

The GE Fanuc Genius I/O IC697MEM719 CMOS expansion memory module should be installed in accordance with the applicable programmable controller installation manual. During installation, the installers should verify that the rack power has been turned off first. The 64-pin connector should be plugged into the connector on the baseboard, and the installers should engage all the snaps. After all of the proper installation steps have been followed, the installers should place the IC697MEM719 memory module in rack and switch on the power. For CPU installation, memory clearance is made through the use of the MS-DOS software or by using the Windows programming software. For the PCM, follow all of the manufacturers’ instructions to ensure proper installation.
