5. Configuring the FieldServer as a TIWAY Server
For a detailed discussion on FieldServer configuration, please refer to the FieldServer
instruction Configuration mM anual (Virtual PLC) . 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 TIWAY Client.
The configuration file tells the FieldServer about its interfaces, and the routing of data
required. In order to enable the FieldServer for TIWAY 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.
Note that in the tables, * indicates an optional parameter, with the bold legal value being the
default.
