Posted 8 Mar 2020 You will always get a drift in time when using a timer in any plc to do something like this. Either install a real flow switch in the field or if you have to use time the get a RTC (Real Time Clock) and deduct the times from starting to stopping off each other to be more precise Share this post Link to post Share on other sites
