5.Configuring the FieldServer as a Canatal Satchnet Protocol Driver Server
For a detailed discussion on FieldServer configuration, please refer to the instruction manual for the FieldServer. The information that follows describes how to expand upon the factory defaults provided in the configuration files included with the FieldServer (See “.csv” files on the driver diskette).
This section documents and describes the parameters necessary for configuring the FieldServer to communicate with a Canatal Satchnet Protocol Driver Client (Master)
The configuration file tells the FieldServer about its interfaces, and the routing of data required. In order to enable the FieldServer for Canatal Satchnet Protocol Driver communications, the driver independent FieldServer buffers need to be declared in the “Data Arrays” section, the FieldServer virtual node(s) needs to be declared in the “Server Side Nodes” section, and the data to be provided to the clients needs to be mapped in the “Server Side Map Descriptors” section. Details on how to do this can be found below.
