Difficult App, very little documentation. This is all the help for using the API and there are numerous technical errors. No examples of reading or writing to coils, and no clear output of the send message and reply: "The Modbus addresses are polled using the 6-digit address scheme “Xnnnnnn”. The first digit (“X” ) is the standard Modbus address scheme followed by 5-digit Modbus". I did eventually manage to work out how to use the app myself, but it was not easy. Good documentation required.
