Like HAMs4 & 6 re my 14373, HAM5 needed to have the ST0 L4C to Cartesan matrices corrected.  These signals go to Sensor Correction and Feed Forward and aren't being used now.  So I again checked all the other matrices and yes they were still correct so I reloaded all the matrices.  The platform tripped (I should have expected that and taken the platform down first.)  The untripping of the watchog was not usual and it is noteworthy.

The watchdog medm showed a red Rogue Exc WD.  Usually, a reset all,  a Rogue Exc reset, and finally another reset all will green everything.  This time however that did not work.  The Rogue Exc finally cleared when I hit the reset on the already green SEIHAM5 DACKILLIOP found on the SWWD HAM5 medm.

I'll press Dave as to why this was because it might slow down an operator getting the machine back up.
