M172* RTC day-of-the-week validation

[obscuresc]

Hi,

I'm using the sysClock registers for setting the RTC. I have observed that there is no validation for day-of-the-week. It will range check, but will let you set any time/date combo with any day of the week. It would be nice to have sysClock raise sysClock_Error if the wrong day of the week was entered, or ideally, the day-of-the-week is determined by entering the date time.

I could build a layer in front that does these checks, but the sysClock registers would still exist and risk being used, particularly when coupling to HMI.

Any thoughts?

Hi,

You could find in the integrated parametric AHU Template a function block to calculate the day of the week. 

best regards

Thanks @Bastian_Schmitz .

What would it take to have this built into the back-end of sysClock registers?
