Set the Module Switches
In this application, you must set switches on the 1756-DHRIO
modules for DH+ and the switches on the 1756-CNB modules to the
correct node addresses. The 1756-CNB module in system #1 uses
node address 22 and the 1756-CNB module in system #2 uses node
address 23.
For more information on setting switches on the 1756-DHRIO module,
see
page 1-5. For more information on setting the switches on the
1756-CNB module, see page 4-9.
Set-Up a Routing Table for the 1756-DHRIO Module
Use RSLinx to set-up a routing table for the 1756-DHRIO module in
ControlLogix system #2.
Figure 6.4 shows the routing table necessary
for this example.
Figure 6.4
For more information on how to set-up a routing table, see page 3-5
or the RSLinx online help.
IMPORTANT
The switches on the 1756-CNB modules must match
the information in the 1756-DHRIO routing table.
