Hi all I am having a very weird problem with my control system.
I have flex I/O communicating via control net to a RS5000 processor.
The analog card is a 1794-IF8IH Hart
Here is the problem.I noticed a bad input on channel zero, I have penty of spares in the cabinet so I just moved the transmitter and called my programer to reassign the input.
When I got to the control room i noticed the input on channel one was now reading bad, long story short.....when i simulate an analog signal with my meter on channel zero it shows up on channel one. Simulate on channel one it shows up on channel two. Same for channel three, that is as far as I went. I'm going to assume that the whole card is this way. The whole card is just Temperature transmitters(loop powered) that don't control anything so it's not killing production.
Here is what has been tried to fix the problem.
I have verified the wiring is correct.
I have swapped the card .....no help
I have swapped the base......no help
I have asked my programer to check the configuration at least five times and he says it is right.
One of the big problems is I can't get into the program, it has to be done by someone else.
Please tell me that this is a common problem that is easily fixed.
