High Speed Counter

Hi,
i'm using encoder andHigh Speed Counter to determine
position of the rotating axis and depend on it to give orders.
The problem is that when PLC goes to STOP or switching off the power i losethe HSC's value
The counter's value is reseting and i lose the current axis position.

As i have read here in forum it is possible using time interrupt or hardware interrupt but HSC continues reseting after RUN -STOP.

Can somebody explain me what exactly must i do ?

Thank you

ok,

i did it.
Thank you !
