5. Configuring the FieldServer as a Safetran-SCS-128 Server
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 FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer
to communicate with a Safetran-SCS-128 Client. When configured as a Server, the FieldServer
is unable to keep synchronism with other Servers and Clients on the network if it is being polled
using ‘Poll’ Function (i.e. single byte message). Therefore the FieldServer must be polled with
‘Recall’ request for indication statuses. The FieldServer will always respond with the current
statuses.
The configuration file tells the FieldServer about its interfaces, and the routing of data required.
In order to enable the FieldServer for Safetran-SCS-128 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.
