Value |
Bit No. |
Description |
|
NetworkMessageHeader |
0 |
The JSON NetworkMessage header is included in the NetworkMessages. If this bit is false, bits 3 and 4 shall be 0. |
|
DataSetMessageHeader |
1 |
The JSON DataSetMessage header is included in each DataSetMessage. If this bit is false then the DataSetMessageContentMask for the DataSetWriters is ignored (see 6.3.2.3.1). |
|
SingleDataSetMessage |
2 |
Each JSON NetworkMessage contains only one DataSetMessage. |
|
PublisherId |
3 |
The PublisherId is included in the NetworkMessages. |
|
DataSetClassId |
4 |
The DataSetClassId is included in the NetworkMessages. The NetworkMessage can only contain DataSetMessages with the same DataSetClassId. If DataSetMessages have different DataSetClassIds they must be sent in individual NetworkMessages. |
