Product Notice 2017-10-002 Revision A – Ladder logic editor missing rungs
Logix Designer Ladder Logic Editor Missing All Rungs in a Routine when Online with Correlation after Online Edits are removed in ControlLogix 5580 and CompactLogix 5380
This Product Notice informs you of an anomaly that exists with the Studio 5000 Logix Designer® ladder logic editor. If online changes are made to a ladder logic routine within a ControlLogix® 5580 or CompactLogix® 5380 controller and those changes are assembled or tested, and subsequently removed, all rungs within the routine may be removed when the Go Online command in Logix Designer is used. The rungs will appear as missing within the Logix Designer editor. Controller projects that have been online edited will continue to operate as expected until the Logix Designer Go Online option is used and a subsequent download of the resulting project file is performed.
The affected product is Studio 5000 Logix Designer, all versions v28 and v29, and specific version v30.00. This anomaly will be corrected in versions v30.01 and later, including future release v31. The following Logix Designer products are affected by this anomaly:
Until software correcting this anomaly can be downloaded and installed, customers are advised to avoid the use of the Go Online command. Customers are instead advised to use the Upload command in Logix Designer when connecting to a controller.
If this condition has already occurred and you have not downloaded the project with the missing rungs to the controller, you may upload the original project from the controller to a new Logix Designer project to recover the missing rungs.
If you are not sure if you are affected by this anomaly, you may inspect your project for all ladder logic routines with zero rungs. Within Logix Designer, open the Controller Organizer and view the properties of each ladder logic routine. Those that show “Number of Rungs – 0” may be affected by this anomaly. A person with knowledge of the project should review all zero rung routines to determine if they may be affected by this anomaly. [Refer to the attached PDF documents for example images.]
Correction requires download and installation of corrected product software. Product software may be downloaded from the Rockwell Automation Product Compatibility and Download Center (PCDC).
Important – Product hardware is not affected by this anomaly and may not be returned as part of this notification.
