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.

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.

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  
11  
DCC099 Primserv.csv v3.00u,  
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.

The following commands are supported by the FieldServer for the various PLC types:
