Ethernet Error (TCPP0025): The domain suffix '...' of the network is invalid.

The domain suffix defined as Top-level domain (TLD) under 'Project > Settings | Top-level domain') does not comply with the naming rules for DNS names.

Remedy

Correct the network TLD.
  1. Double-click the error message to directly jump to the TLD specification.
    Alternatively, double-click the 'Project' node in the PLANT and open the 'Settings' editor.
  2. Adapt the setting in the field 'Top-level domain'.

    Note
    Enter the TLD without preceding dot.

    For more information refer to the tooltips in the editor by hovering the mouse pointer on the symbol.
