4. Configuring the FieldServer as a Metasys N2 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 a Metasys N2 Server.
4.1. Data Arrays/Descriptors
The configuration file defines the FieldServer interfaces, and the data routing required. In
order to enable the FieldServer for Metasys N2 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.
Note that in the tables, * indicates an optional parameter, with the bold legal value being the
default value. Where only one legal value is given, no other values for that parameter are
allowed.
