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.

4 DATA ARRAY PARAMETER S
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.

5 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.
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.

5.5 Map Descri ptor E xample: Read Data a nd Ke ep His tory
This Map Descriptor allows the storage of data history. The driver divides the Data Array into sections corresponding to the number of HCSR_Data_Stages.
Current data (stage1) will be stored in the first section and oldest (last stage) data will be stored in the last section in the Data array. Data will be shifted to
next Stage only on change.

Appendix A.1. How Client Stores Data:
The HCS will be polled by an RDBC Map Descriptor and data will be stored in the DA_Current Data Array in the
following fashion if parameter HCSR_Data_Stages >1:
New data is stored as current data.
If data is changed, last current data is moved to 2
data is lost.
When a vehicle has HCS-R equipment installed, Byte 7 (Status of the loop) is equivalent to the “From Loop (0),
On Loop (1) byte listed in Appendix A.1.1. The 20th offset will hold whether data is From Loop or On Loop. To
achieve this, the FieldServer should be configured to store On-Loop and From-Loop data in the same Data
Array. i.e. Map Descriptor Parameter HSCR_Onfrom should be set to Onfrom. Refer to Section 5.3.2
