Table 10.E lists the capabilities of numeric objects, in terms of the decimal
points and negative sign—some objects can display the decimal point and
negative sign, and some cannot; some can accept the decimal point and/or
negative sign as part of the operator’s input, and some cannot.

Set Value Button
The Set Value Button is used to set a PLC input address to a specific value
(a control value) with a single button press. Use this button if there is a
typical set point value that an operator might want to revert to frequently.
You can use a Set Value Button with Numeric Data Display and the
Increment and Decrement Buttons to change and monitor a value
associated with the Set Value Button.
