GE IC693CPU321 – Series 90-30 PLC CPU Module | General Electric Programmable Controller
Engineering Background: The GE IC693CPU321 is a central processing unit module designed for the GE Fanuc Series 90-30 programmable logic controller platform — one of the most widely deployed mid-range PLC families in North American and global industrial automation. Engineered for deterministic real-time control, this CPU module serves as the computational core of a Series 90-30 rack-based system, executing ladder logic, function block, and structured text programs with high reliability in demanding plant-floor environments.
Product Positioning: The IC693CPU321 targets process control, discrete manufacturing, and machine automation applications where a proven, rack-mounted PLC architecture is required. It is a direct fit for engineers maintaining, expanding, or replacing existing Series 90-30 installations, and is equally suitable for new panel builds where GE platform standardization is mandated. Konmask.com supplies this module as a verified, tested unit with full traceability documentation available on request.

Engineering Advantages
- Deterministic Scan Cycle: Fixed-cycle execution ensures predictable response times critical for synchronized multi-axis or interlock-heavy applications.
- Rack-Based Modularity: Slot-based I/O expansion allows engineers to scale from minimal I/O to 2,048+ points without changing the CPU or rewiring the control panel.
- Proven Field Reliability: Series 90-30 CPUs have accumulated decades of runtime hours across global installations — MTBF data available from GE documentation.
- Backward Compatibility: IC693CPU321 programs and configurations are compatible with the broader Series 90-30 ecosystem, protecting existing engineering investment.
- Simplified Diagnostics: Onboard LED status indicators (RUN, FAULT, PWR, BATT) enable rapid field diagnosis without a laptop or HMI.
- Battery-Backed Memory: Retains program and data memory during power loss, eliminating re-download requirements after unplanned outages.
System Architecture & Signal Flow
The IC693CPU321 occupies Slot 1 of the Series 90-30 main rack. On power-up, the CPU performs a self-diagnostic sweep, validates the I/O configuration stored in non-volatile memory, and enters the RUN state. During each scan cycle, the CPU reads all discrete and analog input image table data from the backplane, executes the user program (ladder/FBD/SFC), updates the output image table, and services communication requests — all within a single deterministic scan. Expansion racks communicate via the Series 90-30 bus expansion cable, with the CPU managing all rack-to-rack I/O refresh transparently. Programming is performed offline or online via the serial port using GE Proficy Machine Edition connected to a Windows engineering workstation.

Technical FAQ
Q: Is IC693CPU321 compatible with IC693CPU374 or IC693CPU364?
A: The IC693CPU321 is a lower-memory CPU within the Series 90-30 family. Programs written for higher-spec CPUs (374/364) may exceed the 321’s memory capacity. Always verify program size before substitution.
Q: Can I use Proficy Machine Edition 9.x to program this CPU?
A: Yes. GE Proficy Machine Edition (all current versions) supports the IC693CPU321 via the Series 90-30 target type. Ensure your SNP/SNPX driver is configured for the serial port.
Q: What battery does IC693CPU321 use for memory backup?
A: The module uses a lithium battery (GE part IC693ACC301 or equivalent). Battery life is typically 3–5 years. A BATT LED warning indicates replacement is needed.
Q: Is this module available with a firmware upgrade?
A: Firmware is embedded in the CPU ROM. Konmask.com can advise on available firmware revisions for specific units in stock — contact us with your revision requirement.
Q: Do you provide a test report or FAT documentation?
A: Yes. Factory Acceptance Test (FAT) documentation and power-on test reports are available upon request for critical infrastructure procurement.
