CONFIGURING THE FIELDSERVER AS A PROFIBUS DP MASTER CLIENT
For detailed information on FieldServer configuration, refer to the FieldServer Configuration Manual. The
information that follows describes how to expand upon the factory defaults provided in the configuration
files included with the FieldServer (s
ee “.csv” sample files provided with the FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer to
communicate with up to 125 PROFIBUS DP Slaves.
The configuration file tells the FieldServer about its interfaces, and the routing of data required. In order to
enable the FieldServer for PROFIBUS DP Master communications, the driver independent FieldServer
buffers need to be declared in the “Data Arrays” section, the destination device addresses need to be
declared in the “Client Side Nodes” section, and the data required from the Servers needs to be mapped
in the “Client Side Map Descriptors” section. Details on how to do this can be found below.
NOTE: In the tables below, * indicates an optional parameter and the bold legal value the default.
