PROFIBUS PA interface

5.6.1 Instrument address
Selecting the device address
• Every PROFIBUS-PA device must be given an address. If the address is not set correctly, the
device will not be recognised by the process control system.
• A device address may appear only once within a particular PROFIBUS-PA network.
• Valid device addresses are in the range 1 and 126. All devices are delivered from the factory with
the software address 126.
Setting the device address
The default address can be used to check the function of the device and connect it to an operating
PROFIBUS-PA system. Afterwards the address must be changed to allow other devices to be
connected to the network.
The address can be set by the following methods:
1. The address can be set by the display and operating module VU331 (in the FHX40). To
do so, go to the "profibus params" function group and enter the desired address into the
"instrument address" (*60) function.
2. The address can be set by the ToF Tool - Fieldtool Package. To do so, go to the "profibus
params" function group and enter the desired address into the "instrument address"
function
5.6.2 Device database and type files
A device database file (GSD) contains a description of the properties of the PROFIBUS-PA device,
e.g. the supported transmission rates and the type and format of the digital information output to
the PLC.
Additional bitmap files are required in order to represent the device by an icon in the network design
software.
Every device is allocated an identity code by the PROFIBUS User Organisation (PNO). This appears
in the device data base file name (.gsd).
The Gammapilot M has the ID number 1548(hex) = 5448 (dec).
