DATA ARRAY PARAMETERS 4
Data Arrays are “protocol neutral” data buffers for storage of data to be passed between protocols. It is necessary
to declare the data format of each of the Data Arrays to facilitate correct storage of the relevant data.
Section Title

Column Title
Function Legal Values
Data_Array_Name Provide name for Data Array
Up to 15 alphanumeric
characters
Data_Array_Format
Provide data format. Each Data Array can only take on one
format. Float, Bit, Uint16, Sint16,
Uint32, Sint32, Byte.
Data_Array_Length
Number of Data Objects. Must be larger than the data
storage area required by the Map Descriptors for the data
being placed in this array.

CONFIGURING THE FIELDSERVER AS A DEVICENET MASTER 5
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” files provided with the FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer to communicate
with a DeviceNet Slave.
The configuration file tells the FieldServer about its interfaces, and the routing of data required. In order to enable
the FieldServer for DeviceNet 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.
