Add, Configure, Monitor, and Replace CIP Safety I/O Devices Chapter 5
If the configuration downloaded to the module is not from the original
DNT file, the configuration signature does not match the original. Even
if you recreate the same parameters in a new DNT file, the time and date
portions of the signature are different so the connection to the controller
is not made. If this occurs, click the Safety Connection tab for the
controller that prompted you that the configuration signature is
different and provides you with the option to match the new
configuration signature. However, first re-validate the safety system,
because it is not using the original DNT file.
7. Click Yes.
This takes the controller out of Run mode and prompts you to
download the changes.
8. Click Yes to download the new connection configuration to the
controller.
After the download is complete, place the controller back in Run mode
and the connection to the replacement module is established.
9. Follow your company-prescribed procedures to functionally test the
replaced I/O module and system and to authorize the system for use.
