PG communication with STEP 7 over Industrial Ethernet

Requirements for PG communication
PG communication is possible when the following requirements are met:
● An Ethernet CP is installed in the PG or engineering station or there is a modem/ISDN
● The Ethernet CP must have an address (use default MAC address or set the IP address).
With CPs that have several independent interfaces, for example 1 PROFINET interface and
1 gigabit interface, you can connect your PG or engineering station to the gigabit interface
when networking the PROFINET interface with your plant. You can access the subnet of one
interface from the other interface.
Networking the PG / engineering station
Depending on the configuration of the PG or Engineering Station, the following two situations
are possible when using PG communication:
● PG / engineering station in configured mode
● PG / engineering station in PG mode
If your PG or engineering station is configured for this mode, specify the interface on the PG
or engineering station explicitly with "Set PG/PC Interface".
Follow the steps outlined below:
1. Open the "Set PG/PC Interface" dialog box in the Windows Control Panel.
2. Set the PG/PC interface according to the CPs available on your PG and according to the
For more detailed information on the PG mode and engineering station, refer to /4/

interface set up for remote access.
If you select this configuration when you commission the PG / engineering station, the
interfaces of the communication modules you are using are already known. The option in
"Set PG/PC Interface" is automatically set to "PCinternal".
Once you have downloaded this configuration to your PG / engineering station, you can
exchange PG functions with the accessible nodes in the network with STEP 7 without
requiring any further settings.
