Allen Bradley DF1 Description
The DF1 driver allows the FieldServer to transfer data to and from devices over RS-232 using
DF1 protocol. The FieldServer can emulate either a Server or Client.
The information that follows describes how to expand upon the factory defaults provided in the
configuration files included with the FieldServer.

Configuring the FieldServer as a DF1 Client
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 FS).
This section documents and describes the parameters necessary for configuring the FieldServer
to communicate with a DF1 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 DF1 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.

Appendix A. Driver Notes
Appendix A.1. Continuous Map Descriptors
RS View has been known to crash if it tries to read a Server mapping that is discontinuous.
e.g.
Server map 1: N21: 0-31
Server map 2: N21: 32-100
This will panic the FieldServer and crash RS view as the DF1 will attempt to map N21: 0-100
If set up as:
Server Map 1: N21: 0-100 No problems are experienced
Appendix A.2. Checksum
You can now specify a checksum parameter for the serial connection.
The heading keyword is "Checksum" and the possible values are
1) BCC or 2) CRC-16
If nothing is specified it defaults to BCC.
Example:
Connections
Port,
P1,
Baud,
9600,
Protocol,
DF1_FD,
Checksum
CRC-16
The Checksum is valid for both DF1_FD and DF1_HD.
