System and method for transmitting opc data via data networks, in particular the internet using an asynchronous data connection

The invention relates to a transformer, and transmitting the data OPC system and method through the data network, and a bidirectional valid data connection; the connecting part capable of 1 to the server such status in not and vibrates on Internet of the fire. , (1) (6,7,8) Is first substrate-processing the channel (6a, 7a, 8a) and request connected with the data connected to the automatic system (5) OPC server (4) transmission of the OPC client (1) and data - processing apparatus. The OPC server (4) and used to transmit the channel (6b, 7b, 8b) to respond the request. , Data connector (6,7,8) and long-time opening, permits (1) and OPC server (4), especially Internet time by at least data network between the OPC client with a two-way data transmitting and receiving for time with nothing is made of. And used for ensuring consistency between datum to the data connector (6,7,8) does not receiving to limit the period of rotating, which is provided with an OPC valid, data (4) is pressed multiple time-gap (1) to transmit the pseudo data to a client OPC of the OPC server.
