4.2.6 Connection of the Fieldbus Interface

The WAGO-I/O-SYSTEM 752 for INTERBUS is provided with two 9 pole
D-SUB plug connectors for interfacing to the INTERBUS network.
Input interface: 9 pole D-Sub (male)
Fig. 4-13: "Plug" connection assignment
The INTERBUS input interface is electrically isolated between the fieldbus
and the module.
Output interface: 9 pole D-Sub (female)
Fig. 4-14: "Socket" connection assignment
Note
A jumper in the connection plug (counter plug) of the INTERBUS output inter-
face, between pins 5 (+5 V) and 9 (RBST) instructs the electronics to expect
downstream INTERBUS modules. If this jumper is missing, no downstream
fieldbus units are detected.
Standard cables produced according to the INTERBUS standard include this
jumper in their connector.
The +5 V voltage (pin 5) must not be used for any other purpose.
