Ethernet Error (TCPP0017): The default gateway '...' is identical to the network's broadcast address.

The default gateway set for the network in the properties of the 'Project' node is identical to the address for directed broadcast into the network.

Receivers of a directed broadcast are all devices in the addressed network. The broadcast address is specified by a combination of the address of the target network and setting all host bits to 1.
Example: The address for a directed broadcast into the network 192.168.0.0 with the subnet mask 255.255.255.0 is 192.168.0.255.

Remedy

To fix this error, correct the default gateway.

  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>.
