Connecting PROFIBUS DP via PROFIBUS M12 bus connector
Fig. 5-3 PROFIBUS DP M12 bus connector
For this device version a PROFIBUS DP M12 bus connector with complete internal wiring is supplied in-
stead of the central screw terminals (
see Fig. 5-2
). The bus connection is made via a T-plug that connects
the incoming and outgoing PROFIBUS cable. This version allows pulling the T-plug and disconnecting
the device from PROFIBUS DP without interfering with the bus operation.
Note
Suitable T-plugs and cable sockets/plugs are available as accessories.
