Good morning All,
I have an interesting situation that is happening in a program. They are using a RTC from the HMI to execute a move when the hours are equal to 23 (11PM) and the minutes are equal to 58. with a ONS but what is happening is that it ends up moving it twice because the minutes are rolling back by a count of 5 every 30 seconds or so. so it will go true at 58 then roll back to 53 for 30 seconds then go to 59 and roll back to 52 and so on. when it gets to 3 and then rolls back to 58 the rung goes true again and performs the move another time.
The time on the HMI itself stays true with no dropping back in the minutes. i have not seen this before and i was hoping someone has and can help me diagnose the issue. For the time being i build a 24 hour clock with a timer and counters to make the program function as desired but id rather use the clock.
Thanks,
Dave
