Bus connection
The bus connection is made using the M12 sockets Profibus IN and Profibus OUT. The
address is set on the address switch.

Note, Tip!
Connect ground conductor to FE terminal
Connect incoming Profibus line to Profibus IN
Connect continuing Profibus line to Profibus OUT or screw termination
resistor to the continuing bus terminal.
Note, Tip!
Each Profibus segment must be terminated with a bus terminator. The
termination resistor requires no external voltage.
Unused sockets must be fitted with cover caps to ensure IP 67 protection rating.

Ports
The sensor supply is fused by a PTC. When an overload or short circuit occurs, the affected
output is turned off. The Output remains turned off after the fault is eliminated. The affected
output must be turned off from the controller to clear the short circuit memory.
Note, Tip!
For the digital sensor inputs follow the input guideline per EN 61131-2, Typ 2.
