Ny-Series Instructions Reference Manual (W560 - Omron NY532-5400 Reference Manual

An example of the start at PV operation is provided below. The following table gives the contents of Pro-
gramPattern[].
Step number
Value of ReachSP
Value of TimeWidth
In this example, the value of PresentSP increases from the value for step 0. Therefore, a search is
made only for 40 minutes after the start of processing, i.e., the point where the value of PresentSP
starts to decrease.
Assume that the value of PV at the start of instruction execution is 110. In this case, processing starts
as shown in the following figure where PresentSP equals 110.
Processing is started from this point.
