Do not mix up the S7 Routing function with IP routing.

The example shows how to implement the following way of access via S7 Routing in NetPro.

The engineering computer (also with ibaPDA) is to access the CPU412 controller. The computer and the controller are not directly connected via a common network/bus. The connection has to run over the CPU314C controller. "Passing" the communication through this controller is called S7 Routing.

In our example, engineering computer and CPU314C are also located in two different (logic) subnets. You need an (IP) router for establishing a communication connection. This is completely independent of the S7 Routing function and should not be mixed up with it.
