PROFIBUS Interface Description
17.1
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 CMGZ600A-
series tension controller 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 tension controller.
Otherwise there may be problems while setup. Version numbers of firmware and GSD
file are printed to the cover page of this operating manual.

CMGZ622A DP Slave Functional Description
The tension controllers of the CMGZ600A.P-series supports a PROFIBUS link which
operates according to the PROFIBUS DP protocoll according to EN 50170. Hereby
the tension controller operates as DP slave and the control system as DP Master.
Several parameters have to be set and met by the control system.
17.3
Initial Parameters
Initial parameters are sent from the control system to the tension controller once while
initialization. They are nomally set to a fixed value for a 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 tension controller
