factory defaults provided in the configuration files included with the FieldServer (See “.csv”
sample files provided with the FS).
This section documents and describes the parameters necessary for configuring the
FieldServer to communicate with a Modbus Daniels Server.
4.1. Data Arrays/Descriptors
The configuration file tells the FieldServer about its interfaces, and the routing of data
required. In order to enable the FieldServer for Modbus Daniels 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.
Note that in the tables, * indicates an optional parameter, with the bold legal value being the
default.
