4.11 Fieldbus Configuration - Profibus Master
The 105G-PR2 implements a complete Profibus-DPV0/DPV1 master. The hardware is optimized
for high throughput and can be used in mono or multi master networks up to 12 Mbit/s. Up to
125 slaves with a total max of 2048 byte input and 2048 byte output data can be connected.
4.11.1 GSD File
Each device in a Profibus network is associated with a GSD file, containing all necessary
information about the device. In general, the Profibus slave device manufacturer supplies the
relevant GSD files. E-Series Configuration Software uses these files during network
configuration.
4.11.2 Protocol and Supported Functions
The 105G-PR2 implements a complete Profibus-DPV0/DPV1 master and includes the following
features:
• Up to 125 slaves can be connected
• Up to 2048 bytes input &output data
• Up to 12 Mbit/s on Profibus
• RS-485 optically isolated Profibus interface with on-board DC/DC converter
• Configuration via E-Series Configuration Software
• Acyclic Communication (DPV1)
• Alarm Handling (DPV1)
4.11.3 Configuration
Profibus network configuration is performed via the E-Series Configuration Utility. The 105G
Profibus Master provides up to 2048 bytes of inputs and 2048 bytes of outputs in the fieldbus
interface for I/O on the Profibus network. I/O in the fieldbus interface must be linked with I/O in
the radio interface via appropriate fieldbus mappings (see 4.8 Fieldbus Configuration above) for
I/O transfer with the radio network.
Configuration of the Profibus network is through the Profibus Network Config tab in the E-
Series Configuration Software. Through this section, the entire (local) Profibus network
including I/O data transfer with Profibus slaves is configured. Before a Profibus slave is
configured on the network, its corresponding GSD file must be installed. To install a GSD file
choose File Install GSD File. Once the GSD file(s) have been installed, the devices
corresponding to those GSD files will appear as devices on the Profibus DP treeview on the left
side of the network configuration screen.
The Profibus network configuration screen is divided into three main areas (see below). The left
hand Profibus DP treeview displays all the available slaves, i.e. those whose corresponding GSD
files have been installed. The right hand top section Busview displays graphically the devices
that are currently configured on the Profibus network – individual devices can be selected here
and their I/O configuration and other properties viewed/altered. The right hand bottom section
Listview shows the I/O configuration of a particular slave when a slave device is selected in the
busview, or the network configuration (i.e. what slaves are configured and their corresponding
addresses) when the Profibus master node is selected in the busview.
