The IC693PCM311 offloads specialized communication and data parsing tasks from the primary PLC CPU to optimize total backplane bus communication velocity. The module draws 400 mA from the internal 5 VDC rack supply to power its onboard processor, 640 KB memory bank, and dual serial interface hardware. Firmware flash compatibility and deterministic data interchange across the Series 90-30 backplane allow real-time register transfers between MegaBasic program execution routines and CPU memory blocks. Non-volatile retention of loaded execution tasks and communication configuration parameters during power isolation is secured through an integrated lithium backup battery.
Q: What are the backplane power loading specifications for the IC693PCM311 coprocessor?
A: The module draws up to 400 mA of current strictly from the 5 VDC internal backplane power supply bus.
Q: Which communication protocols are supported on the physical serial interfaces?
A: The two physical serial ports support Modbus RTU protocol in both Master and Slave modes, as well as GE Fanuc CCM protocols via the single high-density DB-style connection.
Q: How is program execution state monitored on the module front panel?
A: Real-time operational feedback and hardware status are reported via three front-panel LED indicators displaying active status across Program Mode and Run Mode execution states.
