4-8 Use RSLinx Software to Create a Routing Table
Set the Controller Slot
Setting the controller slot location creates a simple way for the SLC controllers
to exchange data with the ControlLogix controller as long as the SLC
controller is on the same DH-485 network as the module. The SLC controller
can use local messaging to send data to a ControlLogix controller with this
feature. No routing table is required.
The controller slot is the physical location of a ControlLogix controller in a
DH-485 application. The default setting is slot 0. If necessary, use the Channel
Configuration tabs to change the controller slot number.
For more information about using the DH-485 network, refer to Chapter 3,
Use Data Highway 485 Network.
IMPORTANT
This is not the slot location of the 1756-DH485 module, it
is the slot location of the ControlLogix controller where
you want to send the local message.
A. Change the
controller slot, if
needed.
B. Click OK.
