Create a TD timer for 24 hours that increments an MI. When the MI gets to 7, trigger your event and reset the MI.

 

Alternatively, if your event needs to occur at a specific time of day, do a comparison between the RTC and the time you want. When equal, increment the MI. When the MI equals 7, trigger your event and reset the MI.

Hello Flex727,

Use MB0 as a contact for whatever you are needing to do on a weekly basis, but be sure to reset it - or you can change it to a Direct Coil and it will be True for a single PLC cycle.
