Set up Inverters, Meters & Sensors How to set up Modbus access to external equipment This section will show you how to set up access to Modbus devices such as Inverters, Revenue Grade Meters, Weather Stations, and more using the Tigo SMART Mobile App. 3.1. There are two styles of Modbus communication that Tigo supports: Modbus TCP and Modbus RTU. Modbus TCP works over LAN (TCP/IP). Modbus RTU works over a serial line (RS-485).
