Input Instructions (Logical Starts and Intermediate Instructions):
The instruction reads bit status, makes comparisons, tests bits, or perform other types of processing
every cycle and will output an ON execution condition (power flow) when results switch from OFF to
ON. The execution condition will turn OFF the next cycle.
Input Instructions (Logical Starts and Intermediate Instructions):
The instruction reads bit status, makes comparisons, tests bits, or perform other types of processing
every cycle and will output an OFF execution condition (power flow stops) when results switch from
OFF to ON. The execution condition will turn ON the next cycle.
Downwardly Differentiated Instructions (Instruction Preceded by %)
Output Instructions:
The instruction is executed only during the cycle in which the execution condition changed from ON
to OFF and is not executed in the following cycles.

Example
Upwardly differentiated input instruction
ON execution condition created for one
cycle only when CIO 1.03 goes from
OFF to ON.
