Backplane Bus Communication & Firmware Flash Compatibility
The IC693CMM321-KM operates as an independent communications coprocessor module, clearing network-related protocol stacks away from the primary execution core of the PLC. To preserve stable backplane bus communication velocity and guarantee seamless transmission during periodic data exchange, the host controller CPU must run hardware firmware version 6.50 or higher.
Installing this component into baseplates running legacy CPU versions 5.03 through 6.04 enforces firmware flash compatibility interlocks, restricting the system to a single SRTP network link and blocking multi-client Modbus TCP/IP routing. Proper module alignment ensures that peak data packet volume across the AAUI interface does not extend the baseline logic cycle times of the host controller.
Frequently Asked Questions
Q: Does the IC693CMM321-KM support hot-swapping or run-time module extraction?
A: No. The Series 90-30 chassis assembly lacks the isolation circuitry required for online module manipulation. Power to the entire baseplate must be completely switched off before inserting or removing the communication card to prevent data corruption or permanent electronic hardware failures.
Q: What external hardware is required to establish a physical connection to a standard RJ45 network cable?
A: The primary network interface on this module is an Apple Attachment Unit Interface (AAUI) port. To link the module to an Ethernet switch using standard copper media, an external transceiver component matching the media type (such as 10Base-T or 100Base-TX) and a compatible AAUI attachment cable must be physically attached to the faceplate.
Q: What are the distinct functions assigned to the two built-in serial interfaces?
A: The RJ-11 port operates exclusively as a Station Manager port for low-level diagnostic tracing, firmware flashing, and hardware troubleshooting. The 15-pin D-type port operates as an RS-485 serial fieldbus interface, supporting standard protocols like Modbus RTU or SNP to bridge data to local HMIs and adjacent control devices.
Field Installation Guidelines
- Chassis Attachment: Turn off the primary rack power distribution. Align the back circuit card with the slot tracks of the Series 90-30 baseplate, pivot the module top hooks down securely into the rear chassis hinge, and press the lower module frame until the retention latch snaps into place.
- Shielding Ground Base: Tighten the thumb-screws on the AAUI transceiver cable connection to ground the external media adapter shield directly to the module frame. Ensure the 15-pin serial cable shield is bonded at a single point to prevent ground loops.
- Conduit Segregation: Route the external AAUI drop line and serial paths through data cable ways that are distinct and separate from high-voltage AC wires, motor control feeds, or variable frequency drive outputs.
- Convection Spacing: Install the baseplate structure horizontally to allow natural rising airflow to circulate without restriction through the ventilation pathways built into the plastic module housing, keeping temperatures within the 0 to 60 deg C range.
