We have a lot of POINT-IO modules in various places all over our machines. Occasionally one of the daisy chained cables between our 1734-AENTR will fail, bringing everything else on that network down.
What I'm wondering is if there is any way to have a redundancy using the 2 ethernet ports on the 1734-AENTR modules.
Currently they are all daisy-chained together. The current plan is to replace that and run all new dedicated ethernet cables to each 1734-AENTR back to the switch. I'm wanting to also leave the daisy chain in case one of the dedicated cables fail, it can fall back to the daisy chain.
Testing it with my test equipment, I've got a compactlogix going back to a network switch, then I have one 1734-AENTR running to the switch, and daisy chained to the second 1734-AENTR, however once I run another cable from the second 1734-AENTR to the switch, it brings the whole network down.
I'm thinking I may need a managed switch to somehow have a built in fallover, but IT here is useless so I really hope not.
I really hope that makes sense.
