Technical Features and Benefits
The IC693PCM301P is a robust programmable coprocessor module designed to expand the capabilities of GE Fanuc’s Series 90-30 programmable logic controller platform. Its core strength lies in delivering dedicated processing resources separate from the main CPU, which means high-level communication tasks, data logging, and custom logic can run without burdening the core control loop. This separation improves overall system responsiveness — a key advantage in applications where serial device handling or complex data routines can otherwise throttle PLC scan time.
From an architectural perspective, the IC693PCM301P includes a single 25-pin front connector that houses two independent serial ports internally. These ports can be configured for Modbus RTU, GE Fanuc’s proprietary CCM protocol, or MegaBasic and C-language applications, offering considerable flexibility for automation engineers handling mixed protocol environments. For example, consolidating a barcode scanner and a printer through the PCM instead of dedicating individual hardware interfaces simplifies wiring and reduces CPU load.
Robust memory support separates this module from earlier communication expansions — the total memory footprint is 192 KB, with approximately 47 KB available for MegaBasic user programs. For many legacy automation systems, this is more than enough to embed small task-specific applications such as RTU masters, local data aggregation routines, or peripheral drivers without touching the main ladder logic. By integrating coprocessing tasks into the same backplane, engineers can keep the design compact and maintenance-friendly.
Industrial environments demand not just performance but resilience. The IC693PCM301P includes three LED indicators — one for general module status and two for port activity — allowing rapid visual diagnostics during commissioning or troubleshooting. A built-in lithium battery backs up the RAM memory content, preventing data loss during power interruption. These features help maintain uptime and streamline maintenance workflows in discrete and process industries alike.
Because the module draws its operating power from the Series 90-30 backplane bus, there’s no need for an external power supply. With a typical consumption of around 425 mA @ 5 VDC, it fits easily within standard rack power budgets. Whether you deploy it for high-volume serial polling in a conveyor line or for periodic telemetry routines in a water treatment PLC, the IC693PCM301P brings predictable performance with minimal engineering overhead.
