Introduction (2 of 3)
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.

Familiarization (1 of 4)
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

Familiarization (4 of 4)
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

Test Tool Configuration
A real-world setup using the OPC Foundation DA Sample Server and DA Sample Client:
(a) Client to OpcAnalyzer (b) OpcAnalyzer to Server
The DA Client application will
connect to the OpcAnalyzer
The OpcAnalyzer will connect
to the OPC Sample DA Server
(which does not provide a user-interface)

Step 2: Inject an error and observe the response in the OpcAnalyzer:
Step 2. Select the
test script
Step 4a.Observe the trace in the
OpcAnalyzer. A purple line
indicates the OpcAnalyzer has
modified the original response
Step 3. Check
“Script Enabled”
option to inject
the error
Step 4b. Modified
response
Step 1. Select the
OPC interface and
method you
would like to test

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.

Next Steps…
Once your Classic DA Client passes all applicable tests:
•
Conduct Interoperability Testing
•
Conduct Behavior Testing
•
Conduct Resource-efficiency Testing
•
Request Certification in the Test Lab:
