1. Allen Bradley DH+ Description
The DH+ driver allows the FieldServer to transfer data to and from devices using DH+ protocol.
The Communications Adapter card is included with the FieldServer. 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.

4. Configuring theFieldServer as a DH+ 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 DH+ 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 DH+ 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.

Data_Array_Name Provide name for Data Array Up to 15 alphanumeric
characters
Data_Format Provides data format

6. Driver Notes
6.1. 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 DH+ will attempt to map N21:
0-100
If set up as: Server Map 1: N21: 0-100
No problems are experienced
6.2. Checksum
When selecting checksum options for DH+ devices communicating to the FieldServer, take
note that BCC (Block Check Sum) is supported, whereas CRC (Cyclic Redundancy Check)
is not.
6.3. DH+ as FieldServer Server
If the FieldServer is to be polled by the DH+ network, then it is important to declare the
station address in the “FieldServer” portion of the configuration file.
e.g. FieldServer
Title, System_Station_Address
DCC099 Primserv.csv v3.00u, 11
This sets the FieldServer address to 11. The Node_ID on the server side must then be the
same as the station address declared.
6.4. Command Support
The following commands are supported by the FieldServer for the various PLC types:
PLC_Type File_type FNC Read FNC Write Typical
Command
N 1 Range Read 0 Range Write N7: 3, L5
F 1 Range Read 0 Range Write F12: 3, L5
PLC3 B 1 Range Read 2 Bit Write B3/4: 5, l5
N 1 Range Read 0 Range Write N7: 3 , L5
F 1 Range Read 67 Typed Write F12: 3, L5
