VS18/VS26 MAINTENANCE & INSTRUCTION BOOKLET
8.2.8 GSD file
A GSD file is used to identify a Profibus DP/PA device (master or slave). It contains data
making it possible to have manufacturer independent configuration tools. Typical information in
a GSD file is vendor information, baud rates supported, timing information, options/features
supported and available I/O signals. A GSD file must be available for every DP/PA slave. This is
installed into the PLC configuration software loaded into the products catalogue, in the
additional field devices section.
8.2.9 Profibus DP valve island expansion
The modular design of the VS18/VS26 valve island allows easy modifications to the number of
valves while in the field. The system allows single station expansion for up to 4 valve stations.
For more information please refer to section
9 .
The VS18/VS26 Profibus DP valve islands may have to be reconfigured after expansion to
accept the new number of valves. This is controlled by the DIP switch on the Fieldbus PCB (see
section
8.2.4 ).
