Problem: PanelView Plus 6 displays Fatal Error 3B during boot up sequence
In this week’s Tech Files case review, we look at a recent issue uncovered by a user. The user reported that the PanelView Plus 6 displayed “Fatal Error 3B” on the screen when powered up for the very first time. It was stated that the PanelView Plus 6 display module was replaced with a brand new unit, and the existing logic module was reused with the new display module.
A search of Rockwell Automation’s Knowledge Base found this article with a clue to the meaning of Fatal Error 3B:
PanelView Plus 6 startup messages and boot codes
The error code referred to a failed backlight. But there was a note that stated this error message can also occur when the firmware is not compatible with LED display units.
Further investigating found a link to the Installation Instructions for LED display modules, and a very important note:
If you replace a 7-inch, 10-inch, 12-inch, or 15-inch CCFL display with an LED display, you must upgrade the terminal firmware for the device to operate correctly.
A firmware upgrade is not required for configured terminals that include a display module and logic module. The upgrade is required only when ordering an LED display module to replace an existing CCFL display module.
So it was evident that a firmware update was required, but to what version?
That answer came from another Knowledge Base article that further addressed the Fatal 3B error:
Fatal 3B, Failed Backlight error message is displayed
The firmware of the logic module will need to be updated before a LED backlight display module can be used.
- PanelView Plus / PanelView Plus CE 700 to 1500 firmware needs to be updated to version 5.10.11 or later
- PanelView Plus 6 700 to 1500 firmware needs to be updated to version
- 6.00-20140306 or later
- 6.10-20140122 or later
- 7.00-2013619 or later
- PanelView Plus 6 700 to 1500 firmware needs to be updated to version 7.00-20140729 or later if using a 12-inch High Bright display
It appeared that the case was solved. The user installed the firmware update, and reported that the PanelView Plus 6 unit was operational.
