▼Chapter 6Field bus componentsDe-centralized WAGO/I system for UMG 507, UMG 604, UMG 605, UMG 508 and UMG 511AssemblyThe decentralised field bus couplers of the WAGO I/O system are controlled usingthe RS485 Modbus RTU or using the Ethernet TCP/IP. Communication takes placebetween the UMG and one or more bus couplers into which the respective inputs andoutputs are plugged-in. The WAGO I/O system is fixed to a DIN rail. If the RS485is used, a Profibus cable or a suitable cable e.g. Li2YCY (TP) 2x2x0.22 should be usedwhereby the maximum distance between the master and slave must not exceed 1000 m.WAGO standard componentsThe WAGO field bus couplers can generally be used with all plug-in terminals fromWAGO. However, only the most common ones are shown here:Illustration: WAGO coupler with RS485connection (15.06.202) with outputs(15.06.250) and end terminal (15.06.251).Standard WAGO componentsDescriptionField bus coupler, Modbus RTU, RS485for digital and analogue signals,9.6, 19.2, 38.4, 115.2 kBaud, supply voltage 24VDCField bus coupler, Ethernet TCP/IPfor digital signals, supply voltage 24VDCDigital output terminal 2-channel relay, 230 VAC,2 change-over 1AItem No.15.06.20215.06.20415.06.250Digital input terminal, 230VAC2 channel15.06.271Analogue output terminal 2-channel, 0...20mA 15.06.261Analogue input terminal PT100/PT10003 conducter connection15.06.273End terminal 15.06.251Interface cable UMG bus coupler RS485, 5m length 08.02.424The Ethernet field bus coupler 15.06.204 is used if RS485 cablingis not desired or not possible. The coupler reads the UMG507E/604/605/508 and UMG 511 marker status using theEthernet and switches the output terminals 15.06.250 accordingly.The allocation of the marker to the WAGO output takesplace through the web interface of the WAGO coupler.Janitza electronics ® takes over full configuration:Application: diverse control tasks e.g. shutdown of consumers formaximum demand management or fault indication.A program relating to the necessary outputs is loaded on to thecoupler before delivery. The following data is required for thedelivery: future IP adress of the UMG 507/604/605/508/511and WAGO coupler, gateway and SubNetMask and the numberof required outputs. Delivery can only take place once thisdata is provided.183
