The numeric input object settings are defined in the FactoryTalk View when designing an application in a FactoryTalk View Studio.
At run time a numeric input object lets the operator type a value that will be written to a tag in an external device or a tag database. The numeric information must be entered in the format specified by the Regional and Language Options in the Windows Control Panel.
If you specify Maximum and Minimum values in the Connections tab, this creates a range of values that is valid. At run time, if a number is entered that is outside these values, the input object changes color, and an error message is logged to the Diagnostics List, and the download is canceled.
You can also use the option, Updating tag values continuously, to set up an input field to display a value when it is not being used to enter a value. This eliminates the need for creating both input and display objects for a single tag.
