I want to display the remaining value on the HMI - the difference between the set value and the actual value. but somehow I can't do it. It's certainly not difficult, but I don't know how to do it. Thank you very much for the guidance. Lada

I just don't know how to properly set up the NAI2 network input. the value DW44 is written correctly to B009/ON, but not to B182. Please advise what I am doing wrong.

You need an analog network input, which you connect to an amplifier module and terminate everything with an analog marker. You then connect the amplifier's parameter value to the counter's "On" signal. Best regards, Ella_68
