memory failure has occurred.

Description Controller is Unlocked
Possible Cause
Leaving Data Init control state and not locked
The controller is unlocked through the ToolboxST application.
Solution From ToolboxST application, lock the controllers before running safety functions.
337
Description Output exchange disagreement detected
Possible Cause IONet malfunction or hardware problem. For at least one output, a difference was detected between the
controller outputs. This alarm remains active until the controllers agree on all outputs. A difference for non-Boolean data
generally indicates a deviation of more than 10% from the median value or no IONet EGD configuration is present. For
median values near zero, the variation exceeds integer 2 or real value 0.2.
Solution
For the Mark VIe runtime, use the ToolboxST disagreement display (View | Disagreements) to determine which variables
are in disagreement.
In the application, avoid use of global variable 'ControllerID' and avoid the use of sequencing block 'USB_HB'.
Check IONet (switches, cables); rebuild and download application to all processors. If the problem persists, replace the
processor module.

Description Running Application does not match the Branded Application
Possible Cause Application not branded or different from branded version.
Note The purpose of branding is to label a verified safety application, and to ensure that it is running.
Solution
Reload the branded application to the controller and I/O packs.
Use the ToolboxST application to brand the currently running application.
