MVP 2021 Flex727 Posted March 15, 2015 MVP 2021 Report Share Posted March 15, 2015 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. 1 Quote Link to comment Share on other sites More sharing options...

MVP 2021 Flex727 Posted March 30, 2015 MVP 2021 Report Share Posted March 30, 2015 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.
