Modbus-RTU
Modbus-RTU enables the Modbus communication between OpenPLC master and slave through serial. OpenPLC only supports Modbus-RTU master on Linux and Windows. Microrun-time devices (such as Arduino) without an operating system are supported only as Modbus-RTU slaves: https://openplcproject.com/docs/2-5-modbus-addressing/
