6.5.3
Unused PROFINET interface without BUS2F indicator
BUS2F display for a PROFINET interface that is not connected
If no cable is connected to any port of the PROFINET interface, with a networked
PROFINET interface in the configuration this causes the "BUS2F" LED to light up.
If none of the ports should be used and the lighting up of the “BUS2F” LED is unwanted,
delete the networking of the PROFINET interface in the configuration.
6.5.4
Using the CP as an IP router
The CP can be used to forward IP messages from a local network to a higher-level network
and vice versa. The CP controls access permission according to the configuration.
An extensive network with further IP subnets can be connected to one of the Ethernet
interfaces. To allow this, an external router can be configured on this interface that handles
the forwarding for nodes that are not reachable directly. Enter the IP address of this router
for the relevant interface in "Default router" in the STEP 7 interface configuration.
Note
The use of the CP as a universal router between two extensive networks with other subnets
is not supported.
6.6
Port configuration with redundant partners
Using the same port number with redundant partners
As of firmware version V3.2 of the CP, when configuring passive TCP connections between
the CP and a redundant partner, you can configure the local port number of the CP
identically twice.
This is, for example, necessary if the partner is a redundant IEC master.
