5 CONFIGURING THE FIEL DSERVER AS A GE-EGD CLIENT
Historically, one uses the client-server model to describe the operation of most protocols. Recently producer-
consumer model protocols have started to become more numerous. The GE-EGD (Ethernet Global Data) is a
producer-consumer model protocol. In equating the two models it is important to regard the consumer as a
passive (FieldServer) client. Other clients typically are active and poll for new data. The consumer is a passive
client in that waits to digest new data generated by a producer.
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 provided with the FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer to communicate
with a GE-EGD Producer.
The configuration file tells the FieldServer about its interfaces, and the routing of data required. In order to enable
the FieldServer for GE-EGD 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.
