Day depended output

[Smurf]

Thanks for the previous very fast reply.
Another question: how can we activate an output day dependent, let's say activate each Monday at 07 AM output 1 and each Sunday on 8AM activate output 2.

Other question when excuting a PIDDEF: is it correct that we only needs to execute this function once at startup of the program or repeat after some time?

Kind regards

Is this http://www.madras.fife.sch.uk/maths/amazingnofacts/fact050.html the easiest way?

Found something, please correct if wrong
A = (23*DATE[2]/9) + DATE[3] + 4 + DATE[1] + (DATE[1]/4) - (DATE[1]/100) +(DATE[1]/400)- 2
B = A MOD 7
0 = Sunday and 1 = Monday

This seems not working
A = (((23*DATE[2]/9) + DATE[3] + 4 + DATE[1] + (DATE[1]/4) - (DATE[1]/100) + (DATE[1]/400) ? 2) MOD 7))

Then I need to put the dates in some sort of lookup table I think and match the right number wit the right day.

The variable DATE[4] gives the day of the week.  1 for Monday and 7 for Sunday - if this is what you are looking for. You just have to test the variable DATE[4] first, if it matches the day of interest, then further test the time and set the output accordingly.

PIDDEF only needs to be executed once unless you want to change the parameters after sometime. The Integral and derivative historical data will be cleared when PIDDEF is run.

Looking in the manual is sometimes much easier.
