GE Fanuc IC693CPU374-GP Series 90-30 CPU Module
The GE Fanuc IC693CPU374-GP, also cataloged as the IC693CPU374 CPU Module, operates as a dedicated hardware component for central logic processing and real-time network communications within Series 90-30 platforms. Powered by an Intel 80486DX4 processor operating at 133 MHz alongside a dedicated 200 MHz Ethernet processor, the unit processes up to 4,000 discrete I/O points and 9,999 word registers. The module integrates an embedded two-port RJ-45 Ethernet switch supporting SRTP, Modbus TCP/IP, and EGD, plus dual serial channels for direct bus interface execution.

Backplane Bus Communication Velocity & Network Integration
The IC693CPU374-GP interfaces with the standard Series 90-30 backplane bus, driving high-density data exchanges across local and expansion racks. The dedicated 200 MHz communications coprocessor offloads network protocol stacks from the main 133 MHz execution unit, maintaining deterministic backplane scan cycle times during high-volume Ethernet Global Data (EGD) broadcasting. Onboard flash memory structures preserve system configuration registers, while non-volatile RAM maintains runtime register states via a lithium backup battery.
Frequently Asked Questions
Q: What functions do the dual RJ-45 Ethernet ports on the IC693CPU374-GP perform?
A: The two RJ-45 connectors link to an embedded Ethernet switch that supports daisy-chaining network topologies across nodes using SRTP, Modbus TCP/IP, or EGD protocols without external network switches.
Q: How does the CPU maintain program memory during a main power interruption?
A: The 240 KB user RAM relies on an active lithium battery installed on the module faceplate to retain logic program code, register tables, and system status variables.
Q: What are the electrical parameters for powering the CPU module?
A: The module draws power directly from the Series 90-30 backplane bus supply rail, consuming 1.1 A at +5 VDC during normal operations.
Field Installation Guidelines
Power down the Series 90-30 rack assembly before inserting the module into Slot 1 adjacent to the power supply. Align the card edges with the top and bottom chassis guide rails, pressing the unit firmly back until the rear connector seats fully into the backplane socket.
Connect Ethernet network cables to the RJ-45 ports using shielded Category 5e or higher twisted-pair cabling. Route all communication lines in dedicated wire trays separated from AC power lines or high-voltage inductive leads to prevent signal distortion. Verify that the memory backup battery plug connects securely to its panel receptacle prior to restoring main system power.
