Today, it seems that SC1 is behaving the same as SC2.
When I have the terminal block in module 1 of SC1, I blow on the sensor connected to port 0, the software will indicate that both port 0 and port 1 have changed. When I blow on the sensor connected to port 1, the software will not indicate a change in the sensor values.
Nothing was changed overnight that I am aware of other than a power down when we leave for the day. I am not sure what is going on.
Any thoughts on a potential solution to this problem would be greatly appreciated.
On the Wednesday morning before Thanksgiving, the system would not recognize the last SCXI. I wiggled the cable used to daisy chain the 2 SCXIs together. After this, everything worked as expected. Since we have multiple labs at our facility, I was not sure if some other group might have shut off some equipment for the Thanksgiving holiday that was causing problems for our equipment ( I'm old enough to have experienced such things ). Anyway, I waited until today to see if that was a possibility. Since it was still working this morning, I wiggled the cable again and lost connection to the SCXI. My assumption is that there is a problem with the cable which manifest itself in the problems I was seeing.
I want to thank everyone who took a few moments to give me some advice on possible solutions.
