Issue
When numerically evaluating in a program, what day = 1?
Is Sunday or Monday the first day of the week?
Environment
SmartStruxure site which may or may not have Function Block or Script Programming
Cause
What is the first day of the week in SmartStruxure, this may be required when using ">" or "<" logic in the program.
Resolution
One would expect that the first day of the week would be determined by the regional settings. Within SmartStruxure however, Script programs handle this differently from Function Block programs.
The origins of Menta (Europe) use Function Block programs use Monday as the first day of the week and therefore assign a value of 1 to Monday.
Script program which were developed in the US uses Sunday as the first day of the week and therefore assigns a value of 1 to Sunday. These differences are not handled by the regional settings of the local workstation.
*Exercise caution when using Script or Function Block programming which relates to the first day of the week.
