Features:
- IC630CPU301 combines the Series Three CPU and local programmer in one unit.
- Its user memory stores up to 4K words of ladder-control logic.
- The front programmer supports direct program entry and examination.
During each controller scan, IC630CPU301 reads the assigned inputs, solves the stored ladder program, and updates the corresponding outputs.
When a Series Three Data Communications Module is connected, the controller can exchange I/O, register, timer, counter, user-logic, and diagnostic information with a master device.
A retained-system record should tie the CPU suffix and program backup to the installed base, power supply, module positions, and I/O reference assignments.
Apter Power can quote and source the General Electric IC630CPU301 CPU/Programmer Unit, provide the relevant manufacturer documents, and respond to configuration-record and replacement-option enquiries.

Series Three base and module compatibility
- Controller platform: IC630CPU301 is the CPU/Programmer Unit for the modular Series Three PLC.
- Base choices: The controller can be documented with four-, six-, or eight-position Series Three base units.
- AC supplies: IC630PWR310 and IC630PWR314 are the listed AC power-supply choices for this platform.
- DC supplies: IC630PWR320 and IC630PWR324 provide the corresponding DC-source choices.
- Load record: The official Series Three load table assigns IC630CPU301A 150 units at 5 VDC.
Connecting the Series Three controller to a serial master
- Interface module: A Series Three Data Communications Module connects the CPU to the communications link.
- Electrical interface: Direct links use the documented RS-422 interface between the Series Three system and a master.
- Network role: The Series Three controller responds as a slave to a host computer, Workmaster, or Series Six master.
- Accessible data: The link can transfer I/O points, registers, timers, counters, user logic, and diagnostic information.
- Topology: Point-to-point and multidrop arrangements are both supported within the manual’s cable and distance limits.
Using the integrated programmer during controller operation
- Local access: The front programmer provides direct access to the IC630CPU301 control program.
- Program review: Address and data displays support examination of stored program elements and operating values.
- Mode awareness: Run/program state should be recorded before a planned controller change.
- Scan context: Input, logic, and output states are interpreted within the controller’s repeating scan sequence.
- Change control: A verified program copy provides the reference for comparing a replacement controller with the installed unit.
Checking controller state and retained program condition
- Power-cycle response: CPU mode and communications behavior depend on the stored program condition when power returns.
- Diagnostic access: A connected communications master can read documented Series Three diagnostic status information.
- Program integrity: The retained user program should be verified before attributing a restart problem to field I/O.
- Configuration check: CPU suffix, power-supply state, base arrangement, and module assignments belong in the fault record.
- Controlled restart: Confirm the keyswitch and operating mode before returning IC630CPU301 to RUN.
