Interrupt will be generated when count value is equal to reference. For more info refer to S7-1200 System Manual section 6.1.3.4.

All I want to do it compare my current counter value with counter reference value and when they are equal I want to trigger a bit and stop motion of a motor. How can I trigger this bit, what triggers it? Should CTRL_HSC be inside the OB40 instead of OB1 like I am ooing it now? I am not clear!? The problem I have is that after I move my axis several times I seem to accumulate an an error which escalates over the number of axis movements leading me to belive that I am losing pulses because my CTRL_HSC is called in OB1 and I simply compare the counter actual value and my position setpoint and when they are equal I stop motion. But, I don't think I am doing it correctly and using hardware interupt OB40 would be the correct way to go!? Please, help if you can. Attachment My highspeed counter.jpg (1198 Downloads)
