Compiling and Downloading the AS HW Config

 Downloading the Hardware Configuration only takes place after the following steps have been carried out with NetPro:

 The network configuration has been carried out and

connections from the ES to other stations (PC, AS) were set up.

 Connections were also configured between the devices (AS, OS) to allow data exchange during process runtime.

Go to the chapter on NetPro first

Exercise: SIMATIC PC Station/OS HW Config

Station Configuration Editor was created with PCS 7 when

the PC was installed.

Compiling and Downloading the OS HW Config

 Downloading the Hardware Configuration only takes place after the following steps have been carried out with NetPro:

 The network configuration has been carried out and

connections from the ES to other stations (PC, AS) were set up.

 Connections were also configured between the devices (AS, OS) to allow data exchange during process runtime.
