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

, 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.
