Dear Colleagues,
I have a PLC 5/40E in one of our machine. An alarm message “PLC Battery Low” appeared at HMI. I checked the battery and found exact 3V. However I replaced it with a new one. When I plugged inn the battery, Battery low indication on PLC did not OFF. I cycled the power and found that LED OFF and error message removed but after some time, it again appeared and has not been removing yet while battery was OK. Can any body help me out? I think problem is in PLC not in battery
