I have a Allen Bradley Control Logix 1756-L62, and we have an applicattion that takes the time from the PLC. Since a couple of weeks, we have the trouble that the time in the PLC(I check it with RSLogix) it doesn´t match with the real time, and i need to reconfigure it 2 times at day.
It seems like when the PLC lost its power, only lost the hour, not the date (For example: 10/11/2010 8:00pm changes to ----->10/11/2010 11:00am)
Is there a problem with the battery? or Could be another kind of problem?
