Support,
Yes, I have function sending raw data to serial port and am using hyperterminal to log to a file. I have a 1st scan bit to enable PMON 1 in custom function. The output from the device is connected on input 3 of PLC, and assigned PULSE FREQUENCY 1 to variable A. When monitoring online, value in variable A matches the data I am reading from the serial port.
I have not measured with a scope. I will do this and report my findings. Also, if I add the capacitor, is it between input 3 and +24V?
Thanks as always for your direction.
