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?
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.
