The ON/OFF status of the DIP switch pin 6 on the front of the CPU Unit is stored in the DIP Switch Pin

lated manually as a test without using an Input Unit.
z Auxiliary Area Flags and Words
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 Differentiate Monitor Completed Flag (A508.09). The Flag
will turn ON when conditions set for the differential monitor have been met. The CX-Programmer can
monitor and display these results on screen.
