Activating the PROFIBUS DP Bus Termination
If the interface module is operated as the first or last physical device in the PROFIBUS DP or if
you operate one read head on the interface module, this interface module must have a bus ter-
minator (220
).

Bus terminator
Set the slide switch (1) to "on." In all other cases, the slide switch remains in the "off" position.

Connection to the Network
A 9-pin connector is used to connect to the PROFIBUS DP, in accordance with the PROFIBUS
standard. You therefore need a 9-pin D-sub connector that you can plug into the 9-pin D-sub
socket on the device. This connector is not included in the interface module scope of delivery.
Pin assignment for the 9-pin connector
Setting the PROFIBUS Address
Set the PROFIBUS address using the two rotary switches "ID High" and "ID Low." The digits
selected via the two rotary switches together form the PROFIBUS address in hexadecimal for-
mat.
