Hi Guys,
As I am beginner in programming, but however advanced in reading PLC programs. I face an dumb moment which I cannot pass DD
In order to troubleshoot an issue, I have mounted a sensor on a motor output key to have it activated at each revolution.
Aprox RPM of the gearmotor is ~100-150 RPM
I need an estimate RPM value to trend when the issue is occuring.
The system is GE FANUC 90-30 with proficy.
I started with ONDTR with ALWON power and reset timer by POS edge of sensor. than I divide 600 to this value.
The problem is that the timer increases and with sweep time I get increasing values than it divides to zero when the timer resets.
I cannot think a way to hold last value until sensor gets activated again.
I stumbled upon this and cannot see through to make it work.
Can you please help me?
Thank you guys!
