Configuration Example:
The Following example describes a simple configuration of a 905G connected to a simple
Profibus Slave I/O device. Described is the configuration of the local 905G Profibus master
only, for more detailed configuration examples, an application note can be downloaded from
www.elprotech.com.
The example will transfer 8 x digital points from the radio network to the slave device. A
single 16-bit analog value will be transferred from the profibus slave to the radio network.
Several configuration steps via ESeries Configuration Software are required:
• Profibus Network Configuration
• Fieldbus Configuration (Fieldbus Mappings)
• Radio Configuration (I/O or Block Mappings)
1) Profibus Network Configuration
Once the GSD file for the profibus slave has been installed, the slave device can be added to
the profibus network (see Configuration section above). For this example, the slave is a
modular device, therefore we add the necessary I/O modules to the slave. The example
requires 8 x digital points to be transferred to the slave - hence we add the ‘1 Byte Out’
module - and 1 x analog point (16-bit) to be transferred from the slave – hence we add the ‘2
Byte In’ module (see below).
When these modules are added, configuration software automatically picks the next free
fieldbus interface registers (shown in the Input Address and Output Address columns), which
may later be altered by double-clicking on the relevant I/O module. In this example, the
automatically chosen locations are Fieldbus IN locations 0..1, and Fieldbus OUT location 0.
