Inaccurate AI810 Values
hi, I have an AF100 Network consisting of CI522 (Connected to AC450) ,11 S800I/O Stations (Redundant CI820) with AI810,AO810 I/Os.
Recently I have an Inaccurate Reading of one Temperature Transmitter (Rising from 60 C to 67 C and then come back to 60 C) and the Range is 0-120 C.
So I change the Transmitter,Check the Wiring and Finally I changed the AI810 Card but the Problem is Still exist.
Finally I changed the Connection to Another Channel and Now Everything is OK.
SO my Question ,Could the Problem be at MTU TU830V1 or it Could be at the CI820?
Thanks alot

CI820 - Highly unlikely. Its just a modem
TU830V1 - Its possible.
What kind of Temperature transmitter ? When you "checked the wiring" did you loosen and remake all the connections to the TU830 or just check the screws were tight ? Changing the channel may have fixed a bad connection.
