DM430E flickering and glitching along bottom
« on: Today at 05:20:08 AM »
Hi everyone.  We have a new DM430E on the bench that is periodically flickering black lines across the bottom 5 to 10 rows of pixels when colored text and graphics are placed very near the bottom, and when the requested ExecTime is under 30 msec or so.  We stripped down the application to show nothing other than a fixed screen with this text, so no other code is running other than the OS.  It flickers roughly every second for a brief moment, sometimes barely long enough to notice.  We're still trying to narrow it down more, but until then, is this a known issue?  Very latest GUIDE, and I'll get the HWD/OS version tomorrow. 

The ExecWork time is of course always zero when viewed in the Service Tool, so we'll add a bit of code to capture the peak time and periodically reset this capture.

Hello oiltronic,

Please contact PLUS+1 Helpdesk ( https://www.danfoss.com/en/campaigns/dps/plusplus1-support-form/ ) with this issue.
I did a quick search in old cases in the Support database but couldn't find any similar cases.   Maybe someone on the Forum has experienced this in the past?

Test with the latest HWD file and if you don't see any improvement, contact PLUS+1 Helpdesk.


Thank you
