Chapter 5 Add, Configure, Monitor, and Replace CIP Safety I/O
If you download this configuration to a temporary setup, place the module
on the network and it automatically connects to the controller.
If the configuration downloaded to the module was not from the original
DNT file, the configuration signature will not match the original. Even if
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
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, you should 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
SmartGuard 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.
