Appendix A.
Troubleshooting
Appendix A.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 A.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 A.3.
Station Address
AB Message block does not allow for setting of Station address, therefore Node_ID must be set to 0.
