Backplane Bus Communication Velocity and Firmware Flash Compatibility
The baseplate layout supports high-speed local data transfer via the integrated backplane bus communication velocity traces. It provides physical infrastructure for deterministic networks, allowing the modular central processor to achieve deterministic execution rates across local and expanded racks. System configuration updates rely on the firmware flash compatibility of the specific hosted CPU module, while Slot 2 through Slot 5 incorporate mechanical sizing keys to prevent accidental insertion of incompatible hardware, minimizing fault risks during I/O density scaling.
Frequently Asked Questions
Q: Can the IC693CHS397 baseplate function as an expansion or remote rack?
A: No. The IC693CHS397 is designated exclusively as the primary CPU baseplate and must reside at Rack Number 0 within the PLC architecture. It accommodates exactly one modular CPU or specialty module in Slot 1.
Q: What are the cable limits when utilizing the I/O expansion bus connector?
A: The rightmost 25-pin D-shell female connector supports connection to expansion baseplates. The total cumulative length of the expansion cables across the subsystem must not exceed 15 meters (50 feet).
Field Installation Guidelines
- Mount the chassis to the subpanel using the provided panel-mounting tabs, ensuring reliable electrical grounding to the metal backplane enclosure.
- Ensure all incoming system power is disconnected before seating the power supply module into the leftmost unnumbered slot or inserting any I/O modules into Slots 1 through 5.
- Verify that the 25-pin D-shell expansion cable is completely secured via its retaining screws if a multi-rack system extension is implemented.
- Maintain proper separation between low-voltage signal wires connected to adjacent I/O modules and high-voltage power lines running through the wire ducts.
