4. Configuring the FieldServer as a EST3 Client
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 an EST3 Server.
4.1. Data Arrays
The configuration file tells the FieldServer about its interfaces, and the routing of data required. In
order to enable the FieldServer for EST3 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
