Furthermore, an onboard web server allows for remote status checks without specialized software.
The GE Fanuc IC697CPM790, also cataloged as the IC697CPM790 Central Processing Unit, operates as a dedicated hardware component for high-speed instruction execution and backplane bus coordination within Series 90-70 platforms.
Backplane Bus Communication and Firmware Compatibility
The module integrates directly into the Series 90-70 backplane architecture, facilitating deterministic network data exchange and high-speed communication across distributed I/O racks. Firmware flash compatibility ensures seamless system upgrades through standard programming terminals without altering physical wiring layouts, while backplane bus communication velocity licenses govern synchronous master-slave polling rates.
Frequently Asked Questions
Q: What is the processing scan rate executed by this CPU module?A: The onboard 64 MHz processor achieves a nominal scan rate of 0.4 microseconds per boolean instruction function.Q: How is memory protected during sudden input power loss?A: The system utilizes 1 MB of battery-backed internal memory to preserve user logic programs and register states during outages.
Field Installation Guidelines
Power down the system rack completely prior to inserting or extracting the CPU module to prevent backplane bus terminal arcing. Align the module card edges precisely with the designated rack guide slots, press firmly to seat the board connectors into the backplane receptacles, and secure the top and bottom retaining screws to maintain proper mechanical and electrical ground continuity.
