Firmware Revision Matching
Firmware revision matching affects the download process. If the revision of the
controller does not match the revision of the project, you are prompted to
update the firmware of the controller. The Logix Designer application lets you
update the firmware as part of the download sequence if the controller is
safety-unlocked.
Safety Status/Faults
Uploading program logic and going online is allowed regardless of safety status.
Safety status and faults affect the download process only.
You can view the safety status via the Safety tab on the Controller Properties
dialog box.
Safety Task Signature and Safety-locked and -unlocked Status
The existence of a safety task signature and the safety-locked or -unlocked
status of the controller affect both the upload and download processes.
On Upload
If the controller has a safety task signature, the safety task signature and the
safety task lock status are uploaded with the project. For example, if the project
in the controller was safety-unlocked, the offline project remains safety-
unlocked following the upload, even if it was locked prior to the upload.
Following an upload, the safety task signature in the offline project matches the
controller’s safety task signature.
IMPORTANT
To update the firmware of the controller, first install a firmware upgrade
kit. An upgrade kit ships on a supplemental CD along with the Logix
Designer application.
TIP
You can also upgrade the firmware by choosing ControlFLASH™ from the Tools
menu in the Logix Designer application.
