Called to a site and am neck deep currently running, but issues.
Phase 2 completion has been running for almost 2 years no issues. Controller and comms replaced using all of the old IO because it spans many levels.
v28.11, DHRIO card, 115k, 24 remote racks.
The issue is losing INPUT data only (sporadically) for 300-400ms on multiple input cards 10-30vdc 1771-IDB.
**Voltage does not change at the input card
**Blue hose replace
*Cards replaced
*PSU replaced
*RIO adapter replaced
No node collision that the 1756 can see and all RIO adapters are always green.
Thoughts.
