Industrial Coprocessor Solution – GE IC693PCM301 | Series 90-30
Where This Product Is Used
The GE IC693PCM301 Programmable Coprocessor Module is deployed across demanding industrial environments where the main PLC CPU requires supplemental processing power. Typical application scenarios include:
- Automotive Assembly Lines – Offloads complex motion sequencing and quality inspection algorithms from the primary CPU, enabling deterministic cycle times on high-speed transfer lines.
- Chemical & Petrochemical Plants – Executes custom PID loop calculations and safety interlock logic in parallel with the main controller, reducing scan-time bottlenecks.
- Food & Beverage Processing – Handles real-time recipe management and batch control routines while the host CPU manages HMI communications and historian data logging.
- Power Generation & Utilities – Runs turbine governor algorithms and load-shedding logic that demand sub-millisecond response independent of the main scan cycle.
- Packaging & Material Handling – Coordinates multi-axis servo positioning math and conveyor synchronization without burdening the primary Series 90-30 CPU.
- Water & Wastewater Treatment – Executes advanced process calculations (flow totalization, chemical dosing curves) alongside standard ladder logic.

Application-Specific FAQ
Q: Can the IC693PCM301 replace a failed IC693PCM300?
A: Yes. The PCM301 is the direct successor to the PCM300 and is backward-compatible with existing rack slots and backplane connections. Firmware may need to be updated.
Q: What programming environment is used to develop PCM301 applications?
A: GE provides a C-language SDK (PCM Development Kit). Applications are compiled and downloaded to the module via its RS-232 serial port using a standard terminal or GE’s download utility.
Q: How does the PCM301 share data with the host CPU?
A: Through a shared memory window on the Series 90-30 backplane. The host CPU reads/writes data registers mapped to the PCM’s memory space using standard ladder logic instructions.
Q: Is the IC693PCM301 still manufactured by GE?
A: This model is in the mature/legacy phase. Konmask.com specializes in sourcing tested surplus and refurbished units to support ongoing maintenance of installed Series 90-30 systems.
Q: What warranty is provided?
A: All units carry a 90-day functional warranty. Extended warranty options are available upon request.
