Q&A

Q: Does this kit include the baseplates (TP830)? A: Typically, the K02 kit includes the processors and synchronization cables; baseplates are often ordered as separate accessories depending on cabinet layout.

Q: Can I replace a single PM891 within this redundant pair while the system is running? A: Yes, the “hot-swap” capability allows for the replacement of a faulty unit without interrupting the control logic of the primary processor.

Q: What is the maximum number of I/O points this unit can handle? A: While dependent on logic complexity, the PM891 is the most powerful in its series, capable of managing several thousand I/O points across S800 and S900 racks.
