Profibus Module Connection and Configuration

3.1

Adjustment

Figure 3-1 Adjustment switches
Before powering up the Profibus Module, set the two rotary switches so that the module
address matches the address set in your Master configuration tool (the diagram shows
the factory default setting for the rotary switches).
The module automatically detects the network data rate.
3.2

Connection

The module connects to the Profibus network via a standard 9 pin Sub-D connector.
The Profibus Module can be powered through the network cable or externally (24 Vdc).
