procedures on how to transfer applications by using
pass-through.
DH+ Terminal Connections This section describes connections for the DH+ PanelView terminals
including:
•
DH+ ports
•
typical DH+ system configuration
•
making DH+ connections
DH+ Terminal Ports
The DH+ versions of the PanelView terminals (catalog numbers
ending in 8) have a DH+ port and an RS-232 port.
Use the DH+ port to:
•
communicate with a PLC-5 controller on the Allen-Bradley DH+
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.
TIP
If the terminal is the last device on the link, connect a 1/2 watt
terminating resistor across terminals 1 and 2. The value of the
resistor depends on the DH+ baud rate:
•
for 57.6 kilobaud and 115.2 kilobaud, use a 150-ohm resistor
•
for 230 kilobaud, use an 82-ohm resistor
