4. Configuring the FieldServer as a McQuay Micro Tech Open Protocol 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 Field Server).
This section documents and describes the parameters necessary for configuring the FieldServer to
communicate with a McQuay Micro Tech Open Protocol Server.
The configuration file tells the FieldServer about its interfaces, and the rout ing of data required. In order to
enable the FieldServer for McQuay Micro Tech Open Protocol 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 b elow.
