Appendix B. Troubleshooting
Appendix B.1. Continuous Map Descriptors
The Driver is not able to split data between 2 Data Arrays when writing, or to read a Server mapping that is
discontinuous.
For example, on the Server Side:
If:
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.
Appendix B.2. Reading B File Types
It is advisable to read all data from one B type file into the same data array in one contiguous read if possible.
Doing otherwise may result in problems when reading these points.
Appendix B.3. 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.
Appendix B.4. 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. Refer to Section 6.1. This sets the FieldServer address to 11. The
Node_ID on the Server side must then be the same as the station address declared.
