The Modbus RTU, a Fieldbus network, is a serial communication protocol designed for use with programmable logic controllers (PLCs). Simple and robust, the Modbus RTU is the de facto standard communication protocol and a means for connecting industrial electronics.

The Autonics ARIO-C-MR Modbus RTU-based coupler synchronizes the data of all connected I/O modules with Modbus RTU. The coupler determines the physical structure of the node and automatically creates a local process image of all the I/O. It also includes a mixed arrangement of analog (word) and digital (byte) modules.

The process image is divided into input and output data areas.

The ARIO series slim remote I/O offers Ethernet/Fieldbus communication I/O with modular expansion up to 64 units in various I/O types. The coupler modules are available in various communication protocols. The push-in connection method offers simple and easy wiring for improved user convenience. The hot-swap feature allows the terminal unit and body (control) unit of the module to be disconnected from the base (communication) unit without stopping power or communication for easy maintenance.
