> Need to investigate the quality code function of OSISoft Pi （https://docs.osisoft.com/bundle/pi-interface-for-opc-da/page/data-quality-information.html）
>  
> This is the data collected from the OPC server. Each time-value pair has a quality field that indicates the quality of the value.

>  
> The quality value may be an INT32 datatype and each timeseries binds one.
> The quality code could be a global configuration and does not need to main a timeseries schema for each quality code in the MManager.
