DP820 Counter value freezed and not able to reset
Kindly notes the following :
We do using DP820 module attached to AC800M compact control system to read rotating cutter position , it shall be reset every complete one cycle, to do the reset we attached filed proximity switch to the DP820 digital input .
That effect the pulse counter , the value is freeze in the counter register , even by using a variable all time one (high logic) to enable the counter to be rested attached to the counter freeze condition , the case of the register value freezing still exist .
We cannot reset counter register even by download the application program , cold starting of the controller or even by removing the CPU backup battery
I would say that I do mange to find the solution to my case
as I select the digital input in the DP820 to do the reset counter (the DP820 channel counter), we had to realize that It will affect the freeze conditions, in my case I select the freeze conditions =3, we I do need more is to reset the freeze condition, notes that the reset shall be using variable Positive Edge (in our case we call it Reset_Frozene)
