Create the Block Transfer Rungs
The illustration below shows the Rungs 2:0, 2:1, and 2:2. These three
rungs read and write Scrolling List data to and from the PanelView
terminal. This is a bi-directional block transfer. For more information
about block transfers, see Chapter 2, “Planning Applications,” in the
PanelBuilder 1400e Configuration Software for Windows User
