I am trying to read the analog inputs off the T7 using modbus. I was able to successfully read the inputs using python 2.x but and now using 3.x after converting my code over i still have an issue with a conversion function that was provided in the convert_data.py file that was provided on the LabJack site. Are there any solutions for converting the analog values that come across the modbus to a usable value floating point?

Our pymodbus examples download has been updated and now supports Python 3. Try the updated convert_data.py.

Also, pymodbus has Modbus data (payload) decoder methods in the pymodbus.payload.BinaryPayloadDecoder class.
