I’m doing a project that connects to two Allen Bradley PLC5’s. Every once in a while I’ll lose connectivity for a minute or two, then it will come back up. I changed the timeout setting in the connection settings from 2500 to 2000 ms and communication was restored the last time it happened. Coincidence, or is something else going on?
Almost certainly a coincidence as changing any setting and hitting “Save” on a driver will force it to disconnect and reconnect.
What version are you currently running?
