I don't know if there is some easier way to do, i. e. use some other counter, but with S_CU you can simply ignore the PV of the counter, just make a counter to increase/reset and then take the int output value of it (CV) and compare it with your desired preset value. If they are equal, use the signal from the comparison as the starter. In the attachement is an ilustration of what I mean in FBD, in STL it would be possible to do much nicer I think. Anyway, you should get the picture... Attachment S_CU_what_i_mean.JPG (791 Downloads)
