arduino modbus coffee roaster with 2 thermocouples for artisan software

new_probe.ino

/*
 * This sketch programs Ardunio to communicate with Artisan using MODBUS protocol and
 * an inexpensive thermocouple amplifier.
 *
 * Hardware:
 *  Arduino UNO
 *  Thermocouple amplifier (MAX6675)
 *  K-type thermocouple
 *
 * Libraries needed:
 *  https://github.com/adafruit/MAX6675-library and;
 *  https://github.com/smarmengol/Modbus-Master-Slave-for-Arduino
 *
 * Based on:
 *  serialthermocouple arduino example
 *  https://github.com/hallgeirl/coffee-roaster/blob/4d4fa73c9831b0ff3f28752c454011ab70410de8/src/roaster/roaster.ino#L112-L136

hi i wonder how to setting artisan

How to setting on artisan sir?

How to setting on artisan sir?

Can this be compiled in Arduino IDE and uploaded to an Uno because I kept getting a stream of error messages.
