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.
