12 PROFIBUS Interface Description
12.1 GSD File
The PROFIBUS DP Master has to know which devices are connected to the PROFIBUS
network. For this purpose the GSD file is required. The GSD file for the EMGZ600A-series
measuring amplifier can be taken fron the following internet address:
http://www.fms-technology.com/gsd
The GSD file can also be supplied on a floppy disk on request. In this case please contact FMS
customer service.
Read in the GSD file into the PROFIBUS DP Master
How to read in the GSD file into the control system (DP Master) is depending on the used
control system. For further information, refer to the documentation of the control system.
Note
The GSD-file version must match with the firmware version of the measuring amplifier.
Otherwise there may be problems while setup. Version numbers of the firmware and GSD file
are indicated in the cover page of this operating manual.
12.2 EMGZ622A DP Slave Functional Description
The measuring amplifier of the EMGZ600A.P-series supports a PROFIBUS link which
operates according to the PROFIBUS DP protocol according to EN 50170. Hereby the
measuring amplifier operates as DP slave and the control system as DP Master. Several
parameters have to be set and met by the control system.
12.3 Initial Parameters
During the initialization the initial parameters are sent from the control system to the
measuring amplifier once. They are set to a fixed value for a particular machine with the
programming tool of the control system.
The first bytes of the parameter telegram are specified in the EN 50170 standard. an user
segment of 4 bytes is defined manufacturer-specific for the measuring amplifier
Byte Use Value Meaning
0 initial parameter 0 (not used)
1 0 (not used)
2 0 (not used)
3 0 (not used)
