Go Online with the Controller Chapter 7
Understanding the Factors
that Affect Going Online The Logix Designer application determines whether you can go online with a
target controller based on whether the offline project is new or whether changes
occurred in the offline project. If the project is new, you must first download the
project to the controller. If changes occurred to the project, you are prompted to
upload or download. If no changes occurred, you can go online to monitor the
execution of the project.
A number of factors affect these processes, including Project to Controller Match
feature, the safety status and faults, the existence of a safety task signature, and the
safety-lock/-unlock status of the project and the controller.
Project to Controller Matching
The Project to Controller Match feature affects the download, upload, and go
online processes of standard and safety projects.
If the Project to Controller Match feature is enabled in the offline project, the
Logix Designer application compares the serial number of the controller in the
offline project to that of the connected controller. If they do not match, you must
cancel the download/upload, connect to the correct controller, or confirm that
you are connected to the correct controller, which updates the serial number in
the project to match the target controller.
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.
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.
IMPORTANT To update the firmware of the controller, first install a firmware upgrade kit.
An upgrade kit ships on a supplemental DVD along with the Studio 5000
environment.
TIP You can also upgrade the firmware by choosing ControlFLASH from the Tools menu
in the Logix Designer application.
