Set Analog Value Drawing Method
Available in all applications
Used by: Analog Output, Analog Control, Counter, Selector Switch, Totalizer
The Set Analog Value drawing method is used to create a button that operators may click in order to write a specific value to an I/O address of the associated tag. Several may be drawn in order to provide a range of value choices. Note that the configured value is not shown as part of the drawing method – if you would like it to appear (as shown in the following example) the value must be drawn on the page as text.

Set the value that will be written when the completed object is clicked. If the associated tag is an analog output, this may be any value that is legal for that tag. Otherwise, this value should match one of the configured states for the associated selector switch.
If this value is not set, the button will not work.
If set, the operator will need to confirm every value change made by this method.
