link via the processor’s DH+ port.
• communicate with an SLC 5/04 controller (Channel 1 port) on
the Allen-Bradley DH+ link via the processor’s DH+ port.
• communicate with a ControlLogix controller on the
Allen-Bradley DH+ link via the 1756-DHRIO module.
• transfer applications over the DH+ link from a computer with a
DH+ connection.
Use the RS-232 port to:
• transfer PanelView applications between a computer and the
DH+ terminal using a direct connection.
• connect a printer. For connection details, see the last section in
this chapter.
