Compilation errors in arduino 1.8.6
Saw it had compilations issues relating to arduino 1.8.6. Use 1.8.5 as originally compiled in this sketch.
When you encounter an error you'll see a button on the right side of the orange bar "Copy error messages". Click that button. Paste the error in a message here using code fencing.

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. ....
@itglueguy are you using this library: https://github.com/smarmengol/Modbus-Master-Slave-for-Arduino? I realize I hadn't updated the link in the project readme.
I too have those warnings when I compiled it. I have downloaded this library https://github.com/smarmengol/Modbus-Master-Slave-for-Arduino.
