Detailed Technical Specifications

Description

The GE IC697MEM717 memory module is an expansion memory option for GE Fanuc Series 90-70 PLCs. It provides additional memory storage for GE 772 and GE 771 CPUs, enabling enhanced performance and larger data storage capacities. The IC697MEM717 is available in different memory capacities: 64 KB, 128 KB, 256 KB, and 512 KB, allowing for flexible configurations based on the system requirements.

This memory module operates as a daughterboard within the same slot as the CPU, expanding the baseboard memory. It plays a vital role in ensuring memory retention, even during power failures, by utilizing a backup battery. This feature is crucial for maintaining system integrity, especially for long-term operation in industrial environments where power loss may occur unexpectedly.

The IC697MEM717 memory module supports both program storage and data storage. It also ensures continuous error checking through the PLC CPU in the background. This constant error checking is carried out even when the system undergoes power cycling or resets, ensuring that the memory is always reliable.

Memory Retention and Error Checking

The IC697MEM717 module is designed to retain memory for up to 6 months without applied power, thanks to the onboard battery. The module’s error checking system helps detect any discrepancies, ensuring that data remains accurate. The error checking process continues even during hard and soft resets.

Easy Installation

Installation of the IC697MEM717 module is straightforward. It operates as a daughterboard in the same slot as the CPU. Technicians should use Windows programming software or MS-DOS software to clear the memory before installation. For PCM installation, it’s essential to follow the provided instructions for the programmable coprocessor module.

Applications

• GE PLC Systems: Extends memory capacity in GE 772 and GE 771 CPUs.
