An input object can also be set up to display a tag’s current value, eliminating the need to
create separate input and display objects. For details, see “Updating tag values
continuously” on page 17-23.
Using input objects to retrieve and send data
An operator can use numeric and string input objects to retrieve data from and send data
to the value table, so it can be used by programmable controllers, external OPC servers or
DDE devices, or FactoryTalk View memory.
If a graphic display contains several input objects, the operator can select a single object
and then read or write a value, or read or write values for all objects in the display at once.
The operator can also retrieve a series of values from a recipe file, change them, write the
changed values back to the programmable controller, and then save them to a recipe file.
For more information about recipes, see “Creating and restoring recipes” on page 17-38.
