Using quality code¶

The quality code measures the quality of the connection from a data provider to the MindConnect Nano.

If you export the time series value (e.g. with Insights Hub Monitor) you can see the data points with its connected quality code. This helps you to analyze time ranges where no data is available. This will avoid drawing false conclusions from a null value.

The following graphic shows a dataflow overview of the quality code:

If the data provider (e.g. S7 PLC, OPC UA Server) is healthy it sends the Quality Code as 0 and if there are issues depending on protocol usage, the value is non Zero indicating the issue matching quality code.
