問題:
我試著用DataSocket做為OPC client然後在下面的情況下跑會發生錯誤，請問我能如何解決?
- 我在LabVIEW的面板上用DataSocket連接到OPC source. 然而,當我從OPC servers中選擇時，我會收到錯誤訊息:
NI Network Browser Error!
The connection to the server failed!:
error code - 0x80004002
No such interface supported
An OPC interface could not be found
Ensure that the latest opcproxy.dll is installed and that it has been registered - 當我試著跑OPC的內建範例程式，但也會出現錯誤訊息"Error Reading Items". 我看程式中的錯誤叢集中其寫著:
Error -2147467262 occurred at DataSocket Connect.vi
Error: Can't connect to OPC Server.
解答: 這是因為你在Windows200上安裝LabVIEW8.0而沒有在之前安裝OPC Server，要用DataSocket當作OPC Client，你必需手動註冊opcproxy.dll，你可以跑下面的命令:
regsvr32 "C:\WINNT\system32\opcproxy.dll"註: 此路徑可能在您的電腦中會不同，如果無法執行上面的命令，請搜尋您的opcproxy.dll路徑來修正路徑
