4.6 Configuration

4.6.1 Setting the PROFIBUS station address

The PROFIBUS station address for a Navigator AWT540
transmitter can be set locally via the keypad and menus or
remotely by a master using the SET_SLAVE_ADDRESS service.
When the PROFIBUS Master sets the transmitter's station
address, the address is stored and overwrites the address
value previously held in the instrument.
IMPORTANT (NOTE) The transmitter reboots after its
PROFIBUS station address parameter is changed.
During this period it is not visible to any PROFIBUS
masters.
To change the Station Address:
1. Access the PROFIBUS Communication page – see Section
3, page 7.

press the key (below the Select prompt).
IMPORTANT (NOTE) The Baud Rate is a read-only
value.
The current Slave Address setting (for example 70) is
displayed.

4.6.2 Integration using GSD

PROFIBUS devices differ with respect to available functionality
and parameters for each device type and manufacturer. In
order to obtain 'Plug-and-Play' configuration for PROFIBUS,
characteristic device communication features such as
manufacturer name, device name, hardware / software
versions, baud rate and the number and nature of inputs /
outputs are defined in an electronic device data sheet known
as a GSD (Generic Station Description) file.
A GSD file is readable ASCII text file that contains both general
and device-specific specifications for communication. Each of
the entries describes a feature supported by a device. By using
keywords, a configuration tool reads the device identification,
the adjustable parameters, the corresponding data type and
the permitted limit values for the configuration of the device
from the GSD. Some keywords are mandatory, for example,
Vendor_Name; others are optional, for example,
Sync_Mode_supported.
The GSD file for Navigator AWT540 transmitters specifies the
device-specific Ident No. 3402. It conforms to the PROFIBUS
standard, providing a clear and comprehensive description of
each instrument in a precisely defined format. This enables the
system configuration tool to use the information automatically
when configuring a PROFIBUS bus system.
