5.1.1
Interface Configuration
The X1 and X2 network interfaces of the controller are connected with an
integrated configurable 3-port switch, in which the third port is connected to the
CPU.
The two interfaces and configurable switch enable wiring for:
•
One common network where both ports share a common IP address.
•
Two separate networks where each port has its own IP address.
The physical interfaces (ports) are assigned via logical bridges and can be e.g.,
configured via the WBM.

For interface X1, a fixed IP address can be set temporarily (“Fix IP Address”
mode). The setting is carried out with the Reset button (see Section
“Commissioning” > … > “Temporarily Setting a Fixed IP Address”).
Setting a fixed IP address has no effect on the mode previously set.
5.1.1.1 Operation in Switch Mode
For operation in Switch mode, the TCP/IP settings such as the IP address or
subnet mask apply to both X1 and X2.
When switching to Switch mode, the X1 settings are applied as a new common
configuration for X1 and X2.
The device is then no longer accessible via the IP address previously set for X2.
This must be taken into account for applications that use X2 for communication.
5.1.1.2 Operation with Separate Network Interfaces
When operating with separate network interfaces, both ETHERNET interfaces
can be configured and used separately.
