Hello all,
I have a CompactLogix 35E that has been in operation for ,,, much longer then I have worked here!
The problem is, the I/O will drop out intermittently. Output cards go dark, the Analog and RTD card's power lights shut off, Input cards still show the inputs, and if I'm fast/lucky enough and online I can see warning symbols pop up on all of the I/O like they are inhibited.
Then, everything kicks in and the machine takes off again like nothing happened. It isn't a major fault, just a disruption, but it happens a lot.
(the rest is more for flavor, but it might help)
Originally, the machine was alarming and stopping due to a temperature not being in the right range of the set point. On a HMI trend a spike into negative was found and (suspecting a flapping wire) I put in a bounce timer to get us by until we had down time to make the repair.
Now, without the operator needing to walk over and reset the alarm, we noticed a "hiccup" ... and that brought us to the above problem.
Thanks in advance
