Backplane Bus Communication Velocity & Firmware Processing
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.
Frequently Asked Questions
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.
Field Installation Guidelines
- De-energize the Series 90-30 rack power supply and tag out incoming line voltage before attempting hardware insertion or removal.
- Verify that the lithium backup battery is connected correctly to preserve memory retention prior to module mounting.
- Align the module housing with the card guides of any open slot in the Series 90-30 baseplate, pushing firmly until the backplane connector seats completely.
- Tighten the retaining screw at the top of the module to establish chassis ground continuity and prevent movement under operational vibration.
- Connect field communication wiring to the high-density DB-style port using shielded cables, keeping signal cables separated from high-voltage motor circuits to reduce electrical noise.
