This section provides an overview on how to physically connect with various third party devices. The IG21 and IG61 can communicate with third party devices from other manufacturers via Modbus RTU, Modbus TCP, Modbus ASCII, Ethernet IP, MQTT, and OPC-UA. This enables the IG and Samsara cloud platform to be able to read and write data from other PLCs, machines, and sensors related to controlling a process.
The physical connection to these third party devices are outlined in the next sections. Cloud configuration and setting up third party devices within the Samsara dashboard is covered in in our article on Configuring Third Party Devices.
