I have a 2450 IO link controlling the garage door motor and monitoring the door closed position. It has been working with no problem for over a year, until today. When I woke up this morning, the garage door was open The log shows no record of the output or input changing state during the night. I have an event that turns on the garage lights when the door opens and that event ran, so I know exactly when the door opened. So it seems that the input was detected but not logged (possible?) and the output turned on for no apparent reason (very worrisome).
I tested both the input and output from the CAPI controller and both were logged properly.
Now, it could be possible that the contacts of the manual garage door switch (in parallel with the relay) somehow closed, but the switch status still should have shown a change in state.
