PROFIBUS PA Fieldbus
9.1
Introduction
The DPI620G-IS can communicate with devices that use the
PROFIBUS PA Fieldbus implementation. This is achieved via
an integrated modem.
Note: The modem hardware is only included in DPI620G-
IS-PB or DPI620G-IS-FFPB.
This section provides detail of how to connect PROFIBUS PA
device to the DPI620G-IS.

PROFIBUS Configurations
Before setting-up the electrical connections between the
PROFIBUS device and the DPI620G-IS, the correct
configuration should be established.
A PROFIBUS network at its simplest consists of a field device,
2 terminators and a power supply. The terminators and
power supply are available within the DPI620G-IS.
This allows the connection of the DPI620G-IS to:
Already existing networks where the power supply
and termination are already present.
Stand-alone PROFIBUS PA devices.
Any network configuration in between.
Note: The DPI620G-IS internal power supply is current
limited to approximately 30mA.
