tChapter 6Field bus componentsDecentralised WAGO I/O systemfor client-specific programming (APPs)ApplicationClient-specific programming is achieved with the help of the WAGO I/Osystem. The decentralised field bus coupling is controlled via RS485 modbusRTU. Communication takes place between the UMGs and one ormore bus couplers to which the corresponding inputs and outputs aredetachably interconnected.The WAGO I/O system is attached to a DIN rail. As a bus cable, a profibuscable or other suitable cable, such as Li2YCY(TP) 2x2x0.22 should beused, where the maximum distance between the master and slave mayextend to 1000m.Illustration: WAGO coupler with RS485connection (15.06.202) with outputs(15.06.250) and end terminal (15.06.251).Suitable for devices: UMG 604 / UMG 605 /UMG 508 / UMG511The APPs are programmed on an application byapplication basis depending on client requirements.For tendering purposes, an appropriate applicationdescription is required (specifications).A separate homepage is created for each applicationfor displaying the measured values.Possible applications: Compressed air capture viaanalogue inputs, analogue output of calculated ormeasured values, display of physical measured quantitiesetc.Example of client programmingWAGO standard componentsThe WAGO field bus couplers can generally be used with all plug-in terminals from WAGO.
