Extend your function with an input witch triggers the motor to run for one cycle. This trigger you generate in a Time of Day interupt (weekly) after cycle complete you stop the motor again.

Program in CPU properties OB 10 to start every week with a starting date on a sunday. In OB10 you set a M-bit i.e. M30.0 In your FC, you start the motor with M30.0 And you start a Timer (on delay), best use SFB4 TON, this timer can handle longer times. With timer output reset M30.0. Now your motor runs every sunday at start time you have given in Hardware config. And motor stops when timer is on. Regards, Marcjan Attachment example.pdf (216 Downloads)
