The "Link down" port status is used for deactivation, as it is retained even after a
device restart. If the port status is "disabled", please note that this is set to
"enabled" again after a device restart using the "Loop Detection" function.
2.2 Separate Network adapter and IP addresses
The service bridge enables direct Ethernet access (ISO Layer 2 - MAC level) from
the plant bus to subordinate PROFINET networks.
For ISO Layer 3 access (IP) to the different subnets, an IP address multihoming on
the ES is required. IP addresses Multihoming means that a device has several
network addresses. For this purpose, a separate network card (NIC - Network
Interface Controller) is recommended at the Engineering Station (ES). Several IP
addresses are assigned to this network card according to the PN networks to be
accessed.
The following example shows how it works:
Figure 2-3
The ES has a CP 1623 for communication on the plant bus. This is configured with
the IP 192.168.100.1 (255.255.255.0) and is used for loading the CPU, among
other things.
In addition to the CP 1623, a second network card (NIC) is available in the ES for
accessing the PROFINET networks. The NIC for PROFINET has three IP
addresses:
192.168.10.1 (255.255.255.0): for access to the Web Based Management
(WBM) of the Service Bridge and access to the SCALANCE SC
192.168.11.1 (255.255.255.0): for access to the PN network at Port 2 of the
Service Bridge
192.168.12.1 (255.255.255.0): for access to the PN network at Port 3 of the
Service Bridge
