Links: #1619 CalendarTime attributes "occType"

Page: 24


Paragraph: Table 15 and 16

Category: Issue for edition 2 of this part

Issue: The calendar Setting Year/WeekDay requires to configure the weekDay, month, hr, and mn AND with occ the number of the week in a month.

Number of week in a month = 2, 3, and 4 is ok.

What is the 1st week, 5th or last week? This is not defined in 90-10 nor in 7-3.

There are many different solutions in use all over.


Proposal: I propose that the first week is the first FULL (7 days) week starting with a Monday. The 5th or last week may comprise 1 to 6 days of the next month.

Please provide this definition in 90-10 and 7-3.

I do not understand the problem. According to the table 16 of IEC 61850-7-3:2011, there is no configuration that requires to identify the week within the month.

There is no occType WeekOfMonth defined so far.

If there is a need, please provide requirement as comment to the FDIS of part 7-3, Amd 1

There is another option how to interpret the value of occ:
The number of the nth weekday of a month ... e.g. weekday=Tuesday and occ=2 -> could mean the second Tuesday of each month.
I guess this interpretation is the one we should implement.
