MPM Daylight Saving Time (DST)

Issue

The MPM controller does not adjust the clock automatically when Daylight Saving Time (DST) period occurs

Product Line

SmartStruxure Lite

Environment

SmartStruxureLite Multi-Purpose Manage

Cause

DST settings in the MPM are configured for North America.

Canada and United States: Daylight saving time begins on the second Sunday of March and ends on the first Sunday of November

Europe: Daylight saving time begins on the last Sunday of March and ends on the last Sunday of October

Resolution

In Firmware 2.15, DST properties can be configured in the Controller Configuration Object (CFG1) and/or configuration page. DST start and end configuration on month, week, weekday, hour and offset can be set.

 

If using a firmware version older than 2.15, a script can be used to correct the issue. The script can be found here:
