Hello all,
I have a strange problem with a high speed counter with a s7-1200. I have set up the hack input - it is a 2 channel a/b type which gives 500 pulses per revolution. I also put the ctrl_hsc, created the data blocks etc. For some reason if I read the return directly from the encoder without the ctrl_hsc enabled (put an N/O in front of it) the return reads correctly at 500 pulses per revolution, however if I do it with the ctrl_hsc enabled it only reads about 120 pulses per rpm? I can’t understand or figure out why this is. Is anyone able to offer any advice?
