Messaging Between PLC-5s or SLC5/04s and ControlLogix Controllers 5-3
Set the Module Switches
In this example, Channel A on the 1756-DHRIO module must be set
for DH+. For more information on setting switches on the
1756-DHRIO module, see
page 1-5.
Set-Up a Controller Slot for the 1756-DHRIO Module
In this example, the controller is not located in the default slot (slot 0)
of the ControlLogix chassis. You must use RSLinx to set-up a controller
slot for the 1756-DHRIO module as shown in
Figure 5.2.

For more information on how to set-up a controller slot, see page 3-7
or the RSLinx online help
IMPORTANT
Controller slot values for the other channel, if it is
configured for DH+, should be applied or restored to
default value. In this example, controller values
applied to the channel not used for DH+ messaging
do not matter, but failure to enter a value will
generate a configuration fault for that channel.
