Ethernet Error (TCPP0013): The IP address '...' of device '...' is used more than once in the network.

IP addresses must be unique in the network.

Remedy

To fix this error, enter a unique IP address for the device mentioned in the error message.

  1. Determine the project IP settings of the network specified in the editor 'Project > Settings | IP range', if unknown.
  2. Double-click the error message to directly jump to the suspected IP address specification.
  3. Enter an IP address within the range determined in step 1. Confirm the setting with <Enter>.

Alternative: IP address modification via 'Online Controllers' editor:
When inserting a controller or bus device to the project by scanning the network, the IP address is read from the device. It can be modified directly in the corresponding 'Online Controllers' editor.

Note
This error can only occur if 'IP address assignment method' is set to 'manual' in the device settings and if the automatically entered value derived from the network IP settings ('Project' settings) has been deleted/modified.
