The virtual interface W1 is displayed in the diagnostics view under "Online & Diagnostics".
The hardware ID of the virtual interface is displayed in the system constants in the CPU
properties.
Note
Address change during runtime and restart
When the IP parameters of the virtual interface are loaded, you can then change them via
the display of the CPU, via T_CONFIG or online.
However, note that the originally loaded configuration will be active again after a restart of
the CPU.
Configuration changes
A change of the assigned CP may have an effect on the configuration of the virtual interface:
●
Changes in the configuration
–
Assign a different CP
The configuration is used for the new CP.
–
Deselect the assigned CP
The virtual interface W1 is deactivated and the configuration is lost.
When a CP is assigned again, you need to configure the virtual interface again.
●
Changes to the station configuration
–
Move the CP
If the CP is only moved to another slot of the device, the configuration remains valid.
–
Removing the CP
If the CP is removed from the station, the configuration is retained in the CPU.
In the drop-down list of the parameter group of the CPU, the CP is displayed as
missing and compiling the configuration indicates an error. The missing CP can be
deselected or assigned to another CP.
