Hey guys,
I am facing a weird issue with a micrologix 1400 series PLC installed in my facility.The IP address of the controller is set to default abruptly & as a result its communication with HMIs collapses.The PLC which is otherwise healthy runs for few weeks before IP settings are wiped out & I have to reenter the address for it to work..

What could be the issue? Could this be a hardware fault?
