CTT Issues testing an OPC DA 3 Server
OPC Data Access 3.0 Compliance Test: Test Control Version: 1.00.3.1120 Test Settings Version: 1.03.0.1120
reports errors that look like bugs in CTT.
Following are the screen dumps and explanations:
Issue 1:
Item property 5 reports a wrong data type. The server (checked with the debugger) returns the correct properties. Property 6 seems to be handled as property 5. The property ID column doesn't show the correct IDs. This error is reported only if case 3 is activated.

Issue 2:
An error is reported because the item property 2 (item value) is not returned for a write-only item. This is however correct. The item value must nor be returned for a write-only item. The error is also reported for property 3 (quality) because the server handles quality as the value. How do properties 3 and 4 ( quality and time stamp) need to be handled? Should they be returned for a write-only item?
