How can I change the parameters ‘Start date/time’ and ‘Stop date/time’ of the functional block ‘CLOCK WEEK’ from the front panel of the PR200 or through a variable in akYtec ALP?

Since the ‘CLOCK WEEK’ does not have any inputs you cannot change the parameters of this functional block both from the front panel and through variables.

If you need a modifiable ‘CLOCK WEEK’ in your project, two macros are available in the online macro database as well as a sample program that shows how these macros should be programmed.

To download the sample program, please use this link, open and look for the sample project 'Modifiable Week Clock'.

You may refer to the following video to see the instructions on how to download the macros:
