Ethernet Error (TCPP0009): A free IP address could not be found for the new device type '...'. Increase the address range.

The IP address of each device in the project must be within the IP range set in the properties of the 'Project' node.

Adapt the IP range to provide a free IP address for the device mentioned in the error message.

  1. Double-click the 'Project' node in the PLANT and open the 'Settings' editor.

    Alternative: For many errors which refer to the project IP range, double-clicking the error message directly opens the 'Settings' editor.

  2. Specify/correct the suspected 'IP range' setting(s) and confirm each entry with <Enter>.
