Summary0000939: Table 10 - Bad operation level result codes
Description

Table contains an empty table-row, which is the 2nd from the bottom of the table. Unsure if the row needs to be deleted, or if there was a value there that has been deleted by accident?

Also, the DA Classic Quality code "Last known value" (00010100) per the OPC DA 2.05 specification table titled "Substatus for BAD Quality" on page 163, does not appear to have an OPC UA equivalent. The closest equivalents appear to be:

  • Uncertain_LastUsableValue
  • Uncertain_SubstituteValue
  • Uncertain_InitialValue
TagsNo tags attached.

Added explanation to the specification why Bad_LastKnown cannot be used.

OPC UA (Part 4, section 7.7 - DataValue) specifies the rule:
"If the Server has no known value - in particular when Severity is BAD - it shall return a NULL value"

Therefore the StatusCode "Uncertain_ NoCommunicationLastUsable" is introduced in Part 8 and the FieldBus code Bad_LastKnown shall be mapped to this code.
