UMG 508RS485The RS485 interface is designed as a 9-poleDSUB socket on the UMG508.On this interface, the UMG508 supports the followingselection of protocols:• Modbus RTU• Profibus DP V0 SlaveFor connection, we recommend a 9-pole Profibusplug, e.g. from the company Phoenix,type "SUBCON-Plus-ProfiB/AX/SC“ with articlenumber 2744380.

UMG 508Connection of Bus LinesThe incoming bus line is connected to clamps1A and 1B. The bus line for the next device inthe line is connected to clamps 2A and 2B. Ifthere is no further device in the line, the bus linehas to be terminated with resistors (switch toON).In switch extradata ON, clamps 2A and 2B areswitched off for the continuing bus line.Profibus connector (external)Terminating resistorsD-sub,9 pin,socketD-sub,9 pin,connectorOtherprofibusstationsScrew-type terminalsIllu.
