The M262 Logic/Motion Controller includes a real-time clock (RTC) to provide system date and time information and to support related functions requiring a real-time clock.
The RTC also provides the system date and time to any TMS expansion modules installed on the left side of the controller.
Provided the controller has been powered on for at least 2 hours, the system date and time are maintained for 1000 hours at 25 °C (77 °F) even when the controller is powered off.
This table shows how RTC drift is managed:

To set and calibrate the RTC in EcoStruxure Machine Expert, use either:
oThe Services tab (see M262 Logic/Motion Controller - Programming Guide).
oThe SysTimeRtcSet function block.
