How it works: OpcAnalyzer is a DA Server/Client hybrid:
- Your Client will connect to OpcAnalyzer.
- OpcAnalyzer exposes a downstream Server.
- Clients calls are routed to downstream Server.
- Responses can be modified prior to Client delivery.
Testing Method: Each OPC Interface is tested manually to see:
a. if a service-call is made correctly
b. if the client handles valid responses correctly
c. if the client handles invalid responses correctly

How do I pass? Supported OPC Interfaces must be tested to verify behavior
matches the expected results from the test case document:
www.opcfoundation.org/ua/ctt/help/testcases /
Am I Certified? No, passing the tests in the OpcAnalyzer does not mean you
are certified by the OPC Foundation. It means that your product
is ready for certification in the Test Lab.
Tool used in Lab? The Certification Test Labs use the same version
available on the website: www.opcfoundation.org/opcanalyzer
Use When? The best time is during product development. All Classic DA
products must pass OpcAnalyzer testing prior to release.
Additional Help:A complete user guide is provided with the OpcAnalyzer.

There are (by default) 3 options to get started:• Remote Machine Name: hostname or IP address of the machine where
the OPC Server is installed• Category Filter: DA20, DA30, or Both; filters the list of Servers in the
Server options• Server: OPC Servers available for testing that match the filter criteria

Powerful error-injection scripts are accessible via the Injection tab. Select a script from the drop-down box, and then check the Script Enabled checkbox:
Check the script status for error messages that might occur if error injection fails; important for custom scripts

Step 3: Observe the behavior of the client after the error injection.Did the Client crash? Did it use the data even though its in error? Any error messages?
Client displays the result that was modified by the
Analyzer.This is GOOD
behavior.

Verify the client behavior by referring to the interface, test-case Id and the expected result from the test case documentation:
www.opcfoundation.org/ua/ctt/help/testcases
You can add your own scripts to an interface! Here’s how…
