1 Introduction
The intelligent PROFIBUS-DP gateways of COMSOFT's XPS series allow the
coupling of any serial devices with RS232 or RS422/485 interface to
PROFIBUS-DP according to the European Standard EN50170. The protocol
conversions required for the coupling are executed either by means of a
transparent universal driver or by loadable device-specific converters. The
following figure shows a typical connection:
PROFIBUS-DPRS232 – XPS
RS232/RS422 – XPS-E

2 Setting into Operation
When developing the XPS products, COMSOFT put great stress on an easy
installation. Following this aim, no external devices, e.g. configuration tools on
a PC are required to execute the configuration. All connections are realised by
D-SUB connectors, power plug (EN 60320) or spring clip terminals which can
all be accessed and loosened easily. The PROFIBUS station address is set via
coding switches. All further settings are done via UserParameter of the
SetParam telegram of PROFIBUS-DP. This parameterisation is executed,
simplified by the deliverable GSD file either via the configuration tool of the
connected PROFIBUS-DP Master or by the user program.
