Value Quality Support

The IEC870IP driver can confirm the quality of values received from a device through support for the quality flags implemented by the IEC870-5-101 protocol.

The quality flags are defined by a quality descriptor that is delivered with each value received from a device. The IEC870IP driver then performs a conversion of the quality flags it receives, providing a description of value quality based upon OPC quality.
