4.10.3 Configuration
Profibus network configuration is performed via the ESeries Configuration Utility. The
905G 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 ESeries
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 netowrk configuration (i.e. what slaves
are configured and their corresponding addresses) when the profibus master node is selected
in the busview.
Adding a Slave to the Network
To add a profibus slave to the network, locate the required slave and simply drag the slave
icon onto the visible bus cable on the busview, or right click the required slave and choose
add to network. To add a slave with a specific profibus node address to the network, locate
the required slave and drag the icon to the network listview (ensure that the master node is
