We have four separate Flex I/O branches, for lack of a better term, which feed into one CompactLogix controller, for generator RTD temperatures.
Well, all of a sudden one day, the branch for Unit 2 just stopped responding, and the status lights are behaving in the following manner:
1794-AENT ethernet adapter: module status light flashes green, link light steady green. network light seems to be steady green too.
1794-IR8 (4 each): flashing green, about twice the rate of the AENT's module status flashrate.
I did read that the flashing green on the RTD modules means 'functional, but not configured', but I cannot figure why, or how to resolve this.
All three of the other Flex 'branches' work fine. They are all connected via one ethernet-to-fiber adapter to the PLC in a remote space.
I hope someone can help with this.
