Siemens SIMATIC NET S7-CPs Configuring And Installing page 51

1.7.7 Network/project variant: IP connection across subnets (TCP/IP)
Configuration of the system
If for example, you want to access to the production network from your company
network (PG/PC), you can use an Advanced CP.
Gigabit
(157.55.80.1)
PROFINET interface
The following two cases must be distinguished when configuring the PC.
S The PC is integrated in the STEP 7 project:
For the network attachment of your PG/PC, enter the use of a default router in
the STEP 7 project.
Under "Default router", enter the IP address of the connected interface of the
Advanced CP as the address of the default gateway.
S The PC was not configured with STEP 7:
Enter the route manually in the input prompt. Depending on the operating
system, the command may, for example appear as follows.
− Windows PC:
route −p ADD 157.0.0.0 MASK 255.0.0.0 157.55.80.1
(The parameter "−p" ensures that the entry is saved in the registry and is
therefore retained following a restart on the PC.)
As an alternative, you can also enter these Windows address parameters in
the properties dialog of the Ethernet interface:
Start menu > Settings > Control Panel > Network Connections > properties
of the Interface > select network properties of the connection > entry in the
"Internet Protocol Properties" dialog
