GE Fanuc IC693CPU374-E CPU Module
The GE Fanuc IC693CPU374-E, also cataloged as the IC693CPU374 Single Slot CPU Module, operates as a dedicated hardware component for central logic processing and high-speed data execution within GE Series 90-30 PLC systems. Powered by an AMD SC520 133 MHz processor, the module executes Boolean instructions at 0.15 us while managing 2,048 discrete input and output points across the local backplane. Embedded dual-port 10/100 Mbps Ethernet interfaces handle direct determinism without requiring an external communications coprocessor option.

Backplane Bus Communication and Firmware Velocity
The IC693CPU374-E transfers data across the proprietary Series 90-30 backplane bus using synchronized bus cycles that maintain tight firmware compatibility across legacy and updated chassis backplates. Backplane power draw demands 7.4 W directly from the high-capacity power supply (such as the IC693PWR330 or IC693PWR331) to sustain processor routines alongside dual-port Ethernet switching. The integrated Ethernet stack uses internal hardware acceleration to process Ethernet Global Data (EGD) and Modbus/TCP packets simultaneously without degrading backplane I/O scan intervals or delaying memory allocation updates to the 240 KB configurable memory bank.
Frequently Asked Questions
Q: How does the IC693CPU374-E manage memory retention during system power loss?
A: The module relies on a lithium battery housed in the CPU backplane box to power the volatile RAM. Under standard field conditions, this battery maintains memory state for approximately 1.5 months; installing an optional IC693ACC302 external battery extends retention time up to 15 months.
Q: Can the dual Ethernet ports on the IC693CPU374-E be configured as distinct IP addresses?
A: No, the two RJ45 ports link to an internal unmanaged switch. They share a single MAC address and IP address, serving as a two-port pass-through hub to facilitate daisy-chain network topologies without external network hardware.
Q: Are there physical serial ports present on the IC693CPU374-E faceplate?
A: No, the IC693CPU374-E eliminates physical RS-232/RS-485 serial ports from the front panel. All communications and programming routines execute through the integrated Ethernet interfaces using Ethernet SRTP or Modbus/TCP protocols.
Field Installation Guidelines
Ensure total system power is removed from the Series 90-30 baseplate before inserting or seating the IC693CPU374-E module into Slot 1. Secure the physical mounting latch at the top and bottom of the rack to maintain backplane connector alignment and prevent intermittent bus contact during high-vibration operations. Connect the RAM backup battery leads to the CPU backplane connector prior to energizing the main power supply module.
Run standard shielded twisted-pair (STP) Category 5e or Category 6 Ethernet cables to the front RJ45 connectors, keeping signal lines routed clear of high-voltage AC motor wires and variable frequency drive outputs. Ensure the baseplate grounding terminal links directly to a low-impedance earth ground bus via a 14 AWG or larger copper conductor to mitigate high-frequency noise interference across the Ethernet logic channels.
