Continuously updating tag values
When a numeric or string input field is set to update continuously and
display tag values, its appearance changes to reflect which mode the
field is in. When the field is displaying a value from the programmable
controller or server (display mode), the border around the field is
dotted. When a value has been entered in the field but not
downloaded yet (pending write mode), the border around the field
becomes solid. When a field is ready to receive input (input mode), the
border is solid and the field is surrounded by a highlight box.
The operator can put the field into input mode by setting focus on the
field, uploading to the field, or restoring a recipe to the field. The
operator can set the field back to display mode by pressing the Escape
key.
When you first open a display containing fields set to update
continuously, default focus is given to the first non-updating field in
the index sequence. If all fields in the display are set to update
continuously, no field is given focus until the operator sets focus on a
field.
If an upload fails because of a communication error, question marks
appear in the numeric input fields.
