you recreate the same parameters in a new DNT file, the time and date
portions of the signature will be different so the connection to the
SmartGuard controller is not made. If this occurs, click the Safety
Connection tab for the SmartGuard controller that prompts you that the
signature is different and provides you with the option to match the new
signature. However, you should first re-validate the safety system, because
it is not using the original DNT file.

Run mode and the connection to the replacement module is established.

replaced I/O module and system and to authorize the system for use.
