No. Item Details
1 Set Value Sets the value by which the contents of the address are to be incremented or dec-
remented.
Example: If
Increment/decrement is set to “10,” the contents of the address will in-
crease by 10 each time the button is pressed. If Increment/decrement is set to “–10,”
the contents of the address will decrease by 10 each time the button is pressed.
When indirect specification is selected, the contents of the set address becomes the
increment/decrement value.
2 Maximum
Limit
Sets the maximum limit. Either a fixed value or indirect specification can be selected.
if
Return to the Minimum Value when the Maximum Value is Exceeded is selected,
the value will return to and be set to the minimum value when the maximum value is
exceeded.
Example for a Maximum Limit of 1,000, Minimum Limit of 0, and Incre-
ment/Decrement of 5:
If the present value is 998 and Increment/decrement is executed, the present value
will remain unchanged at 998 if the Return to Minimum Value when the Maximum
Value is Exceeded Checkbox is not selected.
If, however, the Return to Minimum Value when the Maximum Value is Exceeded
Checkbox is selected, 0 will be written to the address.
3 Minimum
Limit
Sets the minimum limit. Either a fixed value or indirect specification can be selected.
If
Return to the Maximum Value when the Minimum Value is Exceeded is selected,
the value will return to and be set as the maximum value when the minimum value is
exceeded.
Example for a Maximum Limit of 1,000, Minimum Limit of 0, and Incre-
ment/Decrement of
−
5:
If the present value is 3 and Increment/decrement is executed, the present value will
remain unchanged at 3 if the Return to Maximum Value when the Minimum Value is
Exceeded Checkbox is not selected.
If, however, the Return to Maximum Value when the Minimum Value is Exceeded
Checkbox is selected, 1000 will be written to the address.
Display Pop-up Menu
When the button is pressed, a pop-up menu will be displayed and the write value can be selected from
the menu. As many pop-up menus as there are label switches can be set. If labels are switched during
NS operations, the displayed pop-up menu will also change. Up to 32 items can be set on pop-up
menus.
On the NS, a scroll bar will be
displayed if there are more than
ten items on a pop-up menu. Use
the scroll bar to display other items
on the menu.
