•
Output Instructions
The instruction is executed only during the cycle in which the execution condition changes from
OFF to ON.
The instruction is not executed in the following cycle.
•
Input Instructions (Logical Starts and Intermediate Instructions)
The instruction reads bit status, makes comparisons, tests bits, or performs other types of pro-
cessing every cycle and will output an ON execution condition (power flow) when the result
changes from OFF to ON.
The execution condition will turn OFF the next cycle.
