Closed AlexWuDDD closed 4 years ago

AlexWuDDD commented 4 years ago

First, i can read the date from the remote Matrikon Simulation Server using your package Second, i try to connect another OPC sever, but what is strange is that Matrikon Explore can connect the remote server, but the application with your package cannot, error is "TryConnect was not successful: Connection failed". And explore and the application on the same machine. OPC Sever is in the another PC. Could you please suggest something for me?

And show the server list can work

konimarti commented 4 years ago

The server list uses the OPCenum.exe when I remember it correctly. The difference between matrikon explorer and this package is that the explorer uses the opc custom interface and this package uses the opc automation wrapper. For further information, i'd suggest that you google for "opc da automation wrapper".
