Issue
The TAC Vista OPC server does not function using the evaluation license file for TAC Vista.
Product Line
TAC Vista
Environment
- TAC Vista Server
- Evaluation License
- TAC Vista OPC Server
Cause
The TAC Vista OPC Server license is a separate license needed when a third-party program should read values from TAC Vista via OPC. The TAC Vista OPC Server license is not included in the Evaluation License for TAC Vista.
Resolution
If you had an existing OPC Server license and this needs to be transferred to a new PC, rehost the license as shown in the article Rehosting a Vista 5 License on the FlexNet License Server.
If you need an evaluation license for TAC OPC Server, please contact your country-level Product Support.
