5. Configuring the FieldServer as a Carrier DataLink Server
For a detailed discussion on FieldServer configuration, please refer to the FieldServer
Instruction 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 Carrier DataLink Client.
The FieldServer can be configured to emulate a Carrier DataLink Device. The use is able to
define a variable number of data tables, allocating a table name a variable number of variables.
The FieldServer may be polled and will respond like a DataLink device. Remote clients can
force variable states by ending write variable commands.
The FieldServer does not emulate any of the alarm buffer/history features of the DataLink
Device.
All variables may be read or written without restriction.
The configuration file tells the FieldServer about its interfaces, and the routing of data required.
In order to enable the FieldServer for Carrier DataLink 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.
