Procure now IC697CPU782 GE Fanuc Series 90-70 CPU Module
Procure now IC697CPU782 to power your complex factory automation with exceptional processing speed and immense memory capacity. The GE Fanuc IC697CPU782 is an industrial-grade Central Processing Unit engineered for the robust Series 90-70 Programmable Logic Controller (PLC) family. Built around a powerful 16 MHz 80386 microprocessor, this single-slot module is designed to execute massive ladder logic programs and complex boolean operations in fractions of a millisecond. Equipped with 512 Kilobytes of battery-backed RAM and an integrated floating-point math coprocessor, this CPU easily handles the intensive PID loop calculations, massive I/O mapping, and data-logging requirements of advanced process control applications, such as chemical refining, automotive assembly lines, and heavy material handling. By deploying this OEM hardware, facilities can ensure deterministic automation control across highly demanding distributed VME rack networks.

Expert Installation and Grounding Advice
When installing the IC697CPU782 into your Series 90-70 VME backplane, rigorous attention must be paid to electrical grounding and electrostatic discharge (ESD) protection. Before sliding the CPU into slot 1 of the main rack, ensure the backplane power is entirely switched off. The CPU module is highly sensitive to voltage spikes during insertion. Furthermore, always verify that the PLC chassis is bonded to an earth ground with a heavy-gauge braided wire. The IC697CPU782 contains a real-time clock and battery-backed RAM; therefore, before commissioning the system, open the front bezel and ensure a fresh lithium battery is securely connected to the designated pins to prevent sudden program loss during facility power outages.
Frequently Asked Questions (FAQs)
Does the IC697CPU782 support Ethernet communication natively? No, this specific CPU module relies on its integrated serial ports for programming and basic communication. To integrate this processor into a modern factory Ethernet network, a dedicated Series 90-70 Ethernet Interface module (such as the CMM) must be installed in an adjacent slot.
What is the function of the front panel key switch? The three-position key switch allows floor managers to physically lock the PLC. In the ‘Run/Outputs Enabled’ position, the process runs normally. The ‘Memory Protect’ position physically prevents anyone from altering the ladder logic via software, securing the machine against unauthorized or accidental reprogramming.
How do I clear a CPU fault on this module? Minor software faults can often be cleared by toggling the front panel switch from Run to Stop and back to Run. However, if the CPU displays a solid red LED fault, you must connect a programming terminal via the RS-485 port to diagnose the exact fatal error code stored in the PLC’s fault table.
