Having an issue where if we lose power to an IO device for a prolonged period, we are finding it won’t reconnect. We are having to go online with the PLC and enabling the IO.
I was going to mess with the Timeout setting, but I am not sure that is the best choice. We have seen issues where the device is down until the next day. So it is hard to say how long it is down for. So I could update the tries to a large number I guess.
Is there a recommendation for this? I found some code on the forum to “reconnect” but it seems to only work for devices that were not Serial.
I remember having to do a routine to reconnect remote serial I/O in the controller about 20 years ago. I looked around for the code but it was programmed in Cyrano which wouldn’t help you much, too much to decode since it was a large program. We found the I/O would not reconnect automatically if communication was lost. It was written much like the I/O enabler routine for ethernet though.
In the subfolder where the zip is uncompressed, there is a readme document on how to set up the chart to re-enable the I/O. If you are having any issues after following the doc, reach out to our support team as they have a lot of experience with that chart - they wrote it themselves.
