Description |
|
NetworkMessageHeader |
0 |
The JSON NetworkMessageheader is included in the NetworkMessages. If this bit is false, bits 3 and 4 shall be 0. |
|
DataSetMessageHeader |
1 |
The JSON DataSetMessageheader is included in each DataSetMessage. If this bit is false then the DataSetMessageContentMaskfor the DataSetWritersis ignored (see 6.3.2.3.1). |
|
SingleDataSetMessage |
2 |
Each JSON NetworkMessagecontains only one DataSetMessage. |
|
PublisherId |
3 |
The PublisherIdis included in the NetworkMessages. |
|
DataSetClassId |
4 |
The DataSetClassIdis included in the NetworkMessages. The NetworkMessagecan only contain DataSetMessageswith the same DataSetClassId. If DataSetMessageshave different DataSetClassIdsthey must be sent in individual NetworkMessages. |
