How do I position my Smart-Wire-DT slaves?4502/11 MN05006002Z-ENTotal length of the ribbon cable: 8.2 mExample of calculation using the formula:The SmartWire-DT gateway does not supply the contactorcoils with sufficient current in this case. An additional powerfeeder module EU5C-SWD-PF1-1 must be inserted after thecontactor with SmartWire-DT slave address 7.The voltage drop in the device supply is non-critical.How do I position mySmartWire-DT slaves?There are no restrictions to the positioning. However, thefollowing recommendations should be heeded:X Arrange the SmartWire-DT slaves of a device group as faras possible in groups on the SmartWire-DT network.X Fit the external device plug to the ribbon cable with suffi-cient spacing.If, for example, the functional elements M22-SWD… orSmartWire-DT I/O modules are arranged next to each other,installation of the external device plugs or later replacementof the SmartWire-DT slaves will be easier.U n = U n-1 - R Ln x (I n + IRB )Result of calculationTotal current in the device supply IVP 0.469 ATotal current in the contactor supply IAUX 3.6 AVoltage drop in the device supply U VP 0.49 VVoltage drop in the contactor supply U AUX 3.77 Vh A minimum clearance of approx. 30 cm has to be main-tained between SmartWire-DT network lines and powercables running in parallel.www.comoso.com
