CONFIGURING THE FIELDSERVER AS A SMC TCP/IP CLIENT 4
For a detailed discussion on FieldServer configuration, please 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 (See “.csv” sample files provided with the FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer to communicate
with a SMC TCP/IP Server.
4.1 Data Arrays/Descriptors
The configuration file tells the FieldServer about its interfaces, and the routing of data required. In order to enable
the FieldServer for SMC TCP/IP 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 that in the tables, * indicates an optional parameter, with the bold legal value being the default.
