Daylight savings - howto set 'day of week' value

DLMSDirector

Hello Mikko,

How should I fill in 'day of week' value in Daylight savings begin/end fields, clock object?

As written in blue book "4.1.6.1 date and time formats examples":

"2) year = 0xFFFF, month =0x FF, dayOfMonth = 0xFE, dayofWeek = 0x07: last Sunday in every year and month;"

so where should I use "7" value in that field?

Best regards, Andrew

Hi, GXDLMSDirector doesn't…

Hi,

GXDLMSDirector doesn't support this at the moment. Our customers do not need this feature, and it's not implemented.

BR,
Mikko
