Button operation setting examples
Here we will describe an example of a button that outputs output signal number 20 at High when input signal
number 20 is high.

condition" window is shown in the figure at right.
(2) Set the operation conditions.
Click <d>, and select the signal type.
If something other than "Unconditionally" is
selected, the input area of the signal number
and the combo box to select the status are
displayed.
Now, select "input signal".

: The kind of the button can be set.
Alternate When the button is clicked once, the button keeps ON state. And
when the button is clicked again, it returns to OFF state.
The signal output is kept too.
Momentary The button stays in an ON state while it is being pushed.
: This sets the preconditions and the signal output operation when the button ON.
The preconditions can be selected as follows. Set the signal number etc., when a
signal state is the precondition. The precondition is judged when the button is ON or
OFF.
- Unconditionally
- State of the specified Input signal
- State of the specified output signal
The signal output operation can be selected as follows. Please set the signal
number etc. when this signal is output.
- Do nothing
- Output the specified output signal
Up to two operation settings can be registered.
Two operation settings operate individually by using their respective preconditions.
Moreover, when High and Low are set to output to the same signal number, and
both conditions become true, Condition2 is given priority.
If the operation is set to signal output, when the button is OFF an inverse signal to
the High/Low state will be output at ON.
