The quality code characterizes the quality of a value when it is transferred from a device to Connector for IEC 60870-5-104.
Use of the device time stamp in Connector for IEC 60870-5-104 affects the quality code:
Flags (bits 12 ... 15) | Description | |
---|---|---|
Bit 12 | Source quality | |
Bit 13 | Source time | The data time stamp was created and added by an external data source. |
Bit 14 | Time corrected | The data time stamp added by an external data source is corrected in the system. |
Bit 15 | Reserved |
You can find additional information on the topic of Quality Codes here: Quality code.
NOTE
If the source quality is 1, it will map the bad quality code to bit 5...2
and bit 11...8
