8.1.4 OPC tunnel

If an OPC server and an OPC client are located on different computers, OPC tunnels are used. This is

a software which is installed on both computers and which acts as client/server itself.

The OPC tunnel for example uses the TCP/IP protocol to transfer the data between the OPC server

and OPC client. OPC tunnels provide for a cross-platform and cross-network communication of OPC-

based applications.

OPC tunnels are the basis for communication...

• between the engineering PC and the Controller (e.g. establishing communication in the »PLC

Designer«, »VisiWinNET®«) Engineering tools.

• between the Controller and other (remote) computers.

[8-1] * The PROFIBUS fieldbus driver can only be accessed via PLC (Logic/Motion). Access via »EASY Starter« or »VisiWinNET®«

Runtime is not provided.
