What You Need To Do
Verify the 1756-DHRIO module
node addresses (page 6-1).
Verify the 1784-KTX driver
configuration (page 6-1).
Test the KTX driver (page 6-2).
Configure the routing table
(page 6-3).
Test the application (page 6-6).
Initiate DH+ to DH+ Communication Via Two
Gateway Modules
In this application, you will establish communication between the two
PLC-5/40C processors over two 1756-DHRIO modules. Change your
existing system to the following configuration.
1756-DHRIO Module
(in slot 1)
node 3
(channel A)
node 4
(channel B)
DH+ Network
(link 100)
PLC-5/40C Processor
(DH+ node 10)
In this example, you send a PLC-5 Typed Write message from the
PLC-5/40C processor at DH+ node 10, link 100, through the 1756-DHRIO
module in slot 1, the backplane of the Control Logix chassis, and the
1756-DHRIO module in slot 3 to the PLC-5/40C processor at DH+ node 1,
link 101.

Verify the 1756-DHRIO Module Node Addresses

Verify that the node addresses for the 1756-DHRIO modules are 3 and 4 and
13 and 14, respectively, as shown. Refer to chapter 2 as necessary.

Verify the KTX Driver Configuration

Verify that the KTX driver is configured as directed on page 3-2.
