Radio Signal Connection via Modbus RTU

I/O signals from Phoenix Contact’s Radioline systems can now be connected directly to control units via the Modbus RTU protocol. For this, the radio master wirelessly collects I/O signals from up to 250 radio stations and maps these to a centrally located Modbus register. This means that the entire radio network can be addressed via one single Modbus slave address. Communication with the control unit is provided via an RS-232 or RS-485 interface.

Remote field stations can be expanded in a modular fashion and individually grouped to facilitate any application scenario. A range of digital and analogue I/O modules is offered for this; these can process signals up to 230V. The radio communication itself is handled via Phoenix Contact’s Trusted Wireless 2.0 radio technology, which ensures reliable transmission even in challenging industrial environments. The entire system can be configured very easily via rotary switches, except for the radio master’s serial parameters, which are set up using free-of-charge software.
