1. Hanning & Kahl HCS-R Description
The Hanning & Kahl HCS-R driver allows the transfer of data from devices over RS-232 HCS-R
protocol. Data is read from HCS-R and current data stored in a specified memory area. The
driver can store the data with its loop data status distinct memory areas depending on wheter
the data is on loop or from loop. The driver is based on section 10.5 of Hanning & Kahl - part
number 40801121. The FieldServer can act as a Client or Server.
Max Nodes Supported

4. Configuring the FieldServer as a HCS-R 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 FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer
to communicate with a HCS-R 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 HCS-R 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.
