I am trying to learn how to use Modbus on PC master with Arduino slave. I am trying to use this link RS485 MODBUS Serial Communication using Arduino UNO as Slave. I need to add ModbusRTU in the Arduino ID library. I could not find the ModbusRTU.zip file. I was going to use Generic Modbus/jbus tester from Schnieder.
Hi @microguy. Here is the download link for the library: https://github.com/smarmengol/Modbus-Master-Slave-for-Arduino/archive/refs/heads/master.zip
