Factory setting
The factory setting of the S900 address is 0.
GSD (generic slave data) file
After physical connection of the stations to the PROFIBUS, the entire DP
system must be configured in the PROFIBUS master. The vendors of
industrial PLCs (Programmable Logical Controllers) or OCS (Open Control
Systems) usable as PROFIBUS masters often provide user-friendly PC-based
configuration tools for this purpose. The configuration is based on electronic
data sheets, the so-called GSD (device data). In the GSD file all slave
characteristics relevant for PROFIBUS operation are specified. A
standardized data format is used to ensure vendor-independent slave
configuration.
Structure of a GSD file
The general structure of the GSD file is specified in EN50170. More detailed
information can be obtained from he PROFIBUS user organization (PNO,
) The GSD files is usually provided by the vendor
or is available in the Internet. The file extension identifies the language:
•
Default: ?=d
•
English: ?=e
•
French: ?=f
•
German: ?=g
•
Italian: ?=i
•
Portuguese: ?=p
•
Spanish: ?=s
At present, the GSD file for S900 is available in English (ABB_04D2.GSD)
and in German (ABB_04D2.GSG).
Every vendor of PROFIBUS slaves delivers a GSD file for the unit. This
enables the user (or his configuration program) to eliminate possible errors
resulting from wrong parameters as early as in the project planning phase.
The GSD file is an ASCII file and an be read with any text editor.
