GE IC610CPU106B One Plus CPU Processors

Configured for discrete logic instruction execution in GE Series One Plus PLC systems, the GE IC610CPU106B (IC610CPU106 One Plus CPU Module) provides direct physical/electrical execution. It handles up to 128 discrete I/O points and interfaces with programming units via an integrated RS-232 serial communication interface.

Hardware Specifications

Backplane Bus Communication Velocity and Compatibility

The GE IC610CPU106B utilizes a dedicated parallel backplane bus architecture designed to maintain deterministic I/O refresh cycles across all 128 digital points. Bus communication velocity is synchronized with the 8-bit microcontroller, yielding a logic execution scan rate of 6 ms per 1K logic instructions. Backplane power distribution delivers regulated 5 VDC directly to the CPU logic circuits, drawing a nominal 300 mA current load. Firmware flash compatibility and memory retention rely on the internal backplane power rail during active state and seamlessly transfer variable data storage to the integrated lithium backup battery when power drops below operating thresholds.

Frequently Asked Questions

Q: Can the IC610CPU106B module be inserted or removed while the rack backplane is powered?

A: No. The IC610CPU106B does not support hot-swapping. System power to the Series One rack backplane must be completely isolated prior to inserting or extracting the CPU module to prevent permanent damage to the edge connectors and onboard CMOS memory components.

Q: How is program logic retained during an extended system power outage?

A: Program code in the 6 kB CMOS RAM and retentive data in the 1 kB memory space are maintained by an onboard lithium battery. Under standard operating conditions of 0 deg C to 55 deg C, the battery provides backup retention for a typical duration of 2 years.

Field Installation Guidelines

1. Verify that the main power supply to the Series One Plus chassis is disconnected before starting installation.
2. Align the IC610CPU106B module with the guide rails of the leftmost slot (Slot 0) in the chassis.
3. Slide the module into the rack until the backplane connectors fully engage.
4. Engage top and bottom locking tabs to secure the housing against vibration.
5. Connect the RS-232 programming cable to the front serial port, maintaining adequate cable strain relief and shield grounding to prevent electrostatic interference.
6. Apply 5 VDC backplane power and verify that the front-panel RUN status LED illuminates green without FAULT LED activation.
