Notice
You can view the IP-ACl with NCM Diagnostics.
When IP access protection is activated, remember that in the following special
case, the IP−ACL is displayed as being empty and IP access protection as being
deactivated:
S There is no connection configured and
S no fixed IP address entered in the IP−ACL and
S and no dynamic IP address is currently being obtained.
As soon as an IP address is entered, for example dynamically, IP access
protection is displayed as activated again..
3.4.6 IP Configuration tab
In this tab, you can decide the route and the method with which the IP address of
the local S7 station is obtained and assigned. With the options available here, it is
also possible to assign IP addresses dynamically outside the STEP 7
configuration.
The following options do not apply to the gigabit interface of the Advanced CPs.
The gigabit interface requires a fixed IP configuration.
Table 3-4 Options in the "IP Configuration" tab
Option
S
Set IP address in the
"Properties − Ethernet
Interface" dialog
A−80
This option is the default.
It means that the IP address is set during the networking of the
Ethernet CP. The IP address of the CP is therefore fixed in the
configuration.
You must select this option if you want to configure specified
connections.
