How to setup RSLinx for PLC-5 and SLC-500 on Data Highway Plus


So you need to know how to setup RSLinx Classic to communicate via USB over Data Highway Plus to an Allen-Bradley PLC-5 or SLC-5/04?

Well you're in luck as in today's article I'll walk you step to setup through how to setup RSLinx as well as the ANC-120e USB to DH+ cable from Automation Networks:

Prerequisites: Before you begin, note that while all PLC-5s have DH+, the only SLC-500 which does is the SLC-5/04.

You'll also need the correct version of RSLogix programming software, and for this procedure the ANC-120e from Automation Networks.

Step 1) Start by plugging your ANC-120e into the USB port on your PC, but not your DH+ network:

Step 2) Next, open Windows Device Manager and find it in the list under “Other Devices”:

Step 3) Right click on it and select “Update Driver Software”

Step 4) Then select “Browse my computer”

Step 5) Next select “Let me pick”

Step 6) Now click on “Network Adapters” and “Next”

Step 7) Then select the manufacturer of “Microsoft Corporation” and the network adapter of “Remote NDIS Compatible device” and then click on Next:

Step 8) If you get a warning click on “Yes.” Finish by clicking on “Close”:

Step 9) Now your ANC-120E should show up correctly in device manager under Network Adaptors:

Step 10) The next step is to assign the ANC-120e an IP address of with a subnet mask of

Note: If you are not familiar with setting a network adapters IP address in control panel I demonstrate how in this video:

Step 11) The next step is to access your ANC-120e to set its Data Highway Plus address. To do this, open a web browser and type in, and then login with the default user name of “admin” and default password of “password”:

Step 12) At the bottom of the main configuration page you will see the settings for the ANC-120e's Data Highway Plus address aka node number (it is in decimal, not octal like RSLinx displays) and baud rate.

Step 13) When done click on “Apply,” and once the page reloads you can close your browser and plug the ANC-120e into your DH+ network:

Step 14) Now launch RSLinx Classic, and then under the Communications menu select Configure Drivers:

Step 15) From the “Available Driver Types” drop down list select “Remote Devices via Linx Gateway”:

Step 16) Accept the default name by clicking on OK:

Step 17) And now enter in the default address of for the ANC-120e, and then click on OK and Close:

Step 18) Now in the RSWho, expand the “TCP-1” driver, then the Device at “,” and then the “Backplane”:

Step 19) Below the backplane expand the “DHRIO” module, then “CH A,” and after a few moments you should see all the devices on your Data Highway Plus network:
