The proprietary Radioline wireless system from Phoenix Contact is now able to transmit I/O signals and serial modbus/RTU data in parallel. Devices with firmware 1.80 or higher support dual mode PLC/modbus RTU, while any older devices can be updated via the PSI-CONF 2.50 software free of charge. I/O modules from the product range can then be added to a Radioline device and additional modbus/RTU slaves can be connected via the serial interface.
This dual mode now makes it possible to transfer information from a serial measuring station and additional I/O data simultaneously. This data can, for example, include door contacts or alarm signals from passive sensors. While in the past a parallel communication path or additional modbus/RTU station was required for this purpose, the I/O function of the Radioline system can now be accessed.
