MisterB.Ohio Posted November 9, 2017 Report Share Posted November 9, 2017 I have an application where the unit needs to go through a calibration cycle every so often. This interval will be specified as a number of days between calibrations and a time of day for it to take place. There is also a screen where the calibration can be triggered manually (or through modbus). I am using a V430 PLC programmed through Visilogic. The timers only go to 100 hours, if the task is scheduled for every 15 or 20 or 30 days, what signal can I use to trigger a count down timer once a day? I can set up a decrementing counter for the number of days and trigger the calibration cycle and reset the "# of days counter." But how do I trigger it?

MVP 2022 Flex727 Posted November 9, 2017 MVP 2022 Report Share Posted November 9, 2017 Use a self-resetting 24 hour timer to increment a counter. When the counter reaches the appropriate number of days, it will trigger the action you want. Then reset the counter to start again. Quote Link to comment Share on other sites More sharing options...

But the calibration needs to start at a specific time. Quote Link to comment Share on other sites More sharing options...
MVP 2022 Flex727 Posted November 9, 2017 MVP 2022 Report Share Posted November 9, 2017 Under Utils/Clock, there are functions that allow you to specify action based on Time of Day, Day of Week, Day of Month, etc. Quote Link to comment Share on other sites More sharing options...
MisterB.Ohio Posted November 10, 2017 Author Report Share Posted November 10, 2017 Thank You. figured it out... by triggering the counter at the specified time of day, it will start when desired. Quote Link to comment Share on other sites More sharing options...
