Select IO Profinet topology
Hi
Doing our first project with Select IO and need some help with communication between PLC and Select IO nodes.
1) Do we need a CI871 for Profinet communication with Select IO nodes, or can our PM867 communicate with it via CN1/CN2 (ethernet)?
2) Select IO nodes has redundant communication cards CI845, how can this work with just one CI871?
Bonus question:
3) Select IO nodes has built-in power voting, does this replace power voter SS823 in SIS applications?
I cannot find any information specifying the Select IO power voting functionality.
From SS823 manual: "The AC 800M High Integrity and the connected S880 High Integrity I/O system (including field power) shall be supplied from a SELV or PELV power supply (e.g. SD83x) connected through the power voter SS823."
Thank you for your time!

Hi,
1. CI871 is communication interface card for profinet protocol, CN1/CN2 in controller cannot be used for Profinet communication.
2. For redundant communication with CI845 redundant CI871 module is required.
