Siemens OPC Software FAQ

2) How do I know if WinPM.Net OPC is sending data and that the quality of the data is good?

Go to following program:
 “C:\Program Files\Siemens\WinPM.Net\system\bin\IONSrvices.TestClient.exe” and run that executable. Click the tab on the left “OPC Tags” and another window will open. You will see all the OPC Tags that WinPM.Net is programmed to send. Double click the registers you want to verify on the left hand side and they should be transferred to the right column. Then press accept, the registers you selected will show up in the previous window with their data value and quality.
