Connecting the Sensor
If you connect several sensors to one interface module, the sensors must have different
addresses. The different addresses will allow the programmable logic controller to allocate the
data to the right sensors. If you connect only one sensor to an interface module, this sensor
always receives the address 0. You can connect up to four sensors to an interface module via
an RS-485 cable. Each sensor is supplied with the default address of 0. Details of how to
change the address of the sensor can be found in the instruction manual for the sensor.
Setting the Number of Connected Sensors
Set the number of connected sensors in the hardware project settings.

Connecting the Interface Module 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 plug is not included with the interface module.
1. Connect the PROFIBUS connector to the D-SUB socket labeled "PROFIBUS."
2. Tighten the lock screws on the connector using a screwdriver.
3. If the assembly is at the beginning or at the end of the PROFIBUS cable, you must connect
the terminator that is integrated in the gateway. To do this, slide the slide switch to the "on"
position.
4. If the assembly is not at the beginning or at the end, you must slide the slide switch to the
"off" position.
5. Set the PROFIBUS address on the fieldbus side of the assembly, using the two rotary
switches labeled "PROFIBUS ID High" and "PROFIBUS ID Low." This setting uses
hexadecimal format.
