Differential Monitoring
When the CPU Unit detects that a bit set by the CX-Programmer has changed
from OFF to ON or from ON to OFF, the results are indicated in the Differenti-
ate Monitor Completed Flag (A508.09). The Flag will turn ON when conditions
set for the differential monitor have been met. The CX-Programmer can moni-
tor and display these results on screen.
