Data Quality

Data quality is supported in the following protocols:

• ArchestrA Message Exchange

• OPC

• SuiteLink

• FastDDE v3

• OPC UA

Data quality is not supported in the following protocols:

• DDE

• FastDDE v2

For those protocols that support it, quality is consistent with OPC Quality. Therefore, data quality from a source that supports it is passed through OI Gateway unmodified if the client also supports it. In the case of a client that does not support it, the quality is dropped. In the case of a data source that does not support quality, if the client supports it, the quality is fabricated and is always good (Exception: When OI Gateway cannot communicate with the target data source).
