The way that you trigger the 'zero' is of importance here. Sharing your code by a screen capture would be helpful. My guess is that you are attempting to read the Z-phase input through a normal program. The input is triggered for a very short time. The PLC cycle exceeds this short time. Plus the filter time for the input is not set correctly in the hardware configuration. Assuming you have a current generation S7-1200 coded with a current generation Step7 -- Link the Z-phase input to the 'sync input' in the hardware configuration of the HSC you are using. Helpful?
