Go Online with the Controller Chapter 7
Understanding the Factors
that Affect Going Online The Studio 5000 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.
Numerous 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 that 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 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 only affect the download process.
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 or can be downloaded from the
Product
Compatibility and Download Center (PCDC) .
TIP You can also update the firmware by choosing ControlFLASH™ from the Tools
menu in the Logix Designer application.
