Introduction
11. Profibus® PA
11.1 Introduction
The DPI 620 Genii can communicate with devices that use Profibus® PA Fieldbus
implementation. This is achieved via an integrated modem.
Note: The modem hardware is only included in DPI620G - PB or DPI620G - FFPB.
This chapter provides detail of how to connect Profibus® PA device to the DPI 620 Genii.
11.2 Profibus® Configurations
Before setting up the electrical connections between the Profibus® device and the DPI 620 Genii,
the correct configuration should be established.
A Profibus® network at its simplest consists of a field device, two terminators and a power supply.
This allows the connection of the DPI 620 Genii to:
• Already existing networks where the power supply and termination are already present.
• Standalone Profibus® PA devices.
• Any network configuration in between.
11.3 Start-up
Profibus® is started by selecting the Profibus® application icon from the Dashboard screen.
CH2 is locked into Volts measure mode. Trying to select a function on CH2 will result in an
information message and the selected function not being set.

Profibus® can also be selected from the Calibrator Task Menu by selecting the Profibus® option
in the Field Communications channel.
Note: Volts measure or none are the only valid mode for CH2 when PROFIBUS® is operational.
