Appendix 6 Examples of computing function settings

Of the computing functions listed in Appendix 2, this chapter explains in detail the timer function,
counter function, peak hold function, set & reset function, and clear function, and gives examples
of their settings.
 Input function command 14: ON (ON timer), 23: ON2 (ON timer 2)
When the input signal is turned ON, the ON command delays the timing of putting out an ON
signal by the setting time of the ON timer, as shown in the figure below. The timer is turned on
only when it receives an ON signal, as illustrated in the timing chart, so no ON signal is put out if
the input signal ON time is shorter than the timer ON time (time during which the timer is
activated). Conversely, when the input signal is turned OFF, an OFF signal is put out
immediately and the timer is reset.
Specifying the timer ON time
Set the timer ON time with the output time data and
specify the output time setting parameter with the input
function parameter which pairs off with the timer
command function.

Output
Set My function-S to "Disabled".
Assign the "no function" to the Terminal S1.
Assign the My function-S output 1 to the Terminal
RY-RC.
Set a delay time (timer ON time) of 1.0 second
for the output time data 1.
Read Terminal S1 input signal. (LD S1)
Activate the ON timer set by a928.
NOP command (no operation)
Transfer the result to the My function-S output 1.
Set to "My function-S always ON".
