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.
Similarly on the Client Side, it is not possible to read sections e.g. 32bits to one array and then 16bits from the
same file type to another array etc. Read Blocks must be contiguous.
Appendix A.2.
Checksum
It is possible to specify a checksum parameter for the serial connection.
Example
// Client Side Connections
Connections
Port
, Protocol , Baud
, Parity , Data_Bits , Stop_Bits , Checksum
P1
, DF1_FD
, 38400 , None
, 8
, 1
, CRC-16
Appendix A.3.
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.
