Issue:
How long will the RTC be running for when there is a power outage?
Product Line:
M580
Resolution:
Clock Back-Up
The accuracy of the real-time clock is maintained for 4 weeks when the CPU power is turned off if
the temperature is below 45 °C (113 °F). If the temperature is higher, the back-up time is shorter.
The real-time clock back-up does not need any maintenance.
If the back-up power is too low, system bit %S51 is set to 1. This value indicates a loss of time when
the power supply was OFF.
