After a short period of readings signal from plc, the value of reading goes up to 4096, instead I'm expecting only 0 and 1.

Sorry I don't really understand

I do not neither. Ported the software to Python, no problem.

4096 is 0010 000 in binary, so actually you are receiving a 1 on the 6th bit. It's probably a bitmapped register.
