Getting 2147942405 - Unknown Error with ABB OPCDA #2

Hello,

Thanks a ton for the library. I get "Getting 2147942405 - Unknown Error!" with ABB OPCDA server. Looks like permissions issue with DCOM. Any suggestions, not a big fan or user or Windows here. Thanks

If you don't want to be bothered by DCOM, you can check this solution. JavaScript/Python is supported natively, and it is a cross-platform solution in client side.
