Overview 1-3
Understanding How Routing
Tables Are Used In some of the example applications, you will need to use routing tables to
route messages between the PLC-5/40C processors if you include a
1756-DHRIO module in the path.
Important:You only need to create a routing table if the message path
includes a 1756-DHRIO module. Ethernet and ControlNet
modules do not require routing tables; however, if a message
path contains a mix of Ethernet, ControlNet, and DH+ network
segments, you must assign each of the network segments in the
path (including ControlNet and Ethernet network segments) a
link number.
Routing tables are stored in 1756-DHRIO modules. Each table contains all
of the “links” (i.e., network segments) in the message path from the source
of the message to the destination of the message. You assign a unique link
number to each of the network segments in the path. Link numbers range
from 1-199.
Important:Do not confuse link numbers with module port numbers or
node numbers. You configure link numbers using software
when you configure the system.These numbers appear only in
1756-DHRIO routing tables. Module port numbers are fixed for
ControlLogix Gateway modules as follows:
In the example applications, you set module node numbers by using the
hardware switches on the 1756-CNB or -CNBR and on the 1756-DHRIO
modules.

2-2 Set Up the Hardware
Set Up the Personal Computer Install the 1784-KTX Card
Install the Ethernet Card
Verify that your PC has an Ethernet card installed. If it does not, install any
commercial variety. Make sure the Ethernet card has a unique IP address to
prevent conflicts with other hardware. Verify also that you have assigned a
subnet address. Then connect the Ethernet card to a hub. See page 3-2 for
more details.
Set the interrupt jumpers on the communication
card (IRQ5 in this example).
Set the switches on the card.
(D700 in this example)
Remember to record the 1784-KTX address:
Channel 1 Address:_________________________
Insert the communication interface card into a
vacant 16-bit ISA or EISA expansion slot and
tighten the screw to secure the card.
For more information, see the KTX

Set Up the Hardware 2-3
Configure the PLC-5 Processors
Set the controlNet network addresses using the two
10-digit rotary switches on top of the module.
To complete the example applications in chapters 8
and 10, set the ControlNet address of one processor
to node 1 and the other processor to node 2.
Set the backplane switches on the I/O chassis for the
PLC-5/40c processors.
Put switches 5 and 6 in the “on” position, then put all
of the others in the “off” position. You need to set these
switches so that you can download the ladder logic
program in the example applications.
Install the processor module.
Install the PLC-5 processor in an appropriate I/O chassis.
If you need help, see the ControlNet 1.5 PLC-5
Programmable Controller User Manual, publication
1785-6.5.22.
 Define the DH+ station address of channel 1A by
setting switch assembly SW-1 on the back of the
processor. (See the side of the processor if you want
to use another address.)
To complete the example applications set the
DH+ node address of one processor to node 10
and the other processor to node 1.
