Example 1: Use when

There's No Differentiated

Example 2: Use to Simplify

In diagram A, below, whenever MOVQ(037) is executed with an ON execution

condition it will move the contents of CIO 1200 to A001. If the execution condition

remains ON, the content of A001 will be changed each cycle that the content of

CIO 1200 changes. Diagram B, however, is an example of how DIFU(013) can

be used to ensure that MOVQ(037) is executed only once each time the desired

execution condition goes ON. Here, the contents of A001 will remain the same

until CIO 022500 goes from OFF to ON.

Note: UP(018) and DOWN(019) can also be used to control differentiated execution of

instructions. Refer to page 123 for details.

Although a differentiated form of MOV(030) is available, the following diagram

would be very complicated to draw using it because only one of the conditions

determining the execution condition for MOV(030) requires differentiated treat-
