HIGH SPEED COUNTER ISSUE

smodlaka112233 Posts: 31 Rating: (0)	hi all i have question about HSC s7-200 HSC is counting up when HSC generate interrupt(CV=PV),can i, in interrupt routine, change PV (for example +10 000)and expect another interrupt when CV=PV again,this time with bigger PV. Does HSC stops counting while preconfiguring PV in interroupt routine?? My idea is to generate interrupt every 1 mm of movement,that means first PV would be 10 000,next 20 000 ... or is better solution to reset CV in interrupt and start again? what method provide better accuracy thanks

Set a VW that counts real mm so it would increase every time CV=PV and the counter would reset himself. In my opinion this way it is a little safer... cause the sky is not the limit in counting numbers in PLC...
