How To Connect To Allen Bradley PLC Via Ethernet

Connecting to an Allen Bradley PLC (Programmable Logic Controller) via Ethernet can be a straightforward process but its important to ensure that you are following proper procedures to avoid any potential connectivity issues. In this example, we will go over the steps you need to take to connect to your Allen Bradley PLC via Ethernet.

Before we begin, you will need to make sure that you have the following items:

• An Allen Bradley PLC with an Ethernet port
• An Ethernet cable
• A computer or device with an Ethernet port
• RSLinx Classic software (available for free download from the Allen Bradley website)

Step 1: Connect the Ethernet cable to the Ethernet port on the Allen Bradley PLC and the Ethernet port on your computer or device.

Step 2: Install RSLinx Classic software on your computer or device. This software allows you to communicate with the PLC over Ethernet.

Step 3: Open RSLinx Classic software and select "New" from the "Communications" menu.

Step 4: In the "Add New Hardware" window, select "Ethernet" from the "Device Type" drop-down menu.

Step 5: In the "Ethernet Device" window, enter the IP address of the PLC. This can typically be found in the PLCs manual or by using the PLCs built-in web server.

Step 6: Click "Finish" to complete the setup.

Step 7: Once the setup is complete, you should be able to communicate with the PLC by opening the "Communications" menu and selecting "PLC" or "Device" depending on the version of RSLinx Classic.

Its important to note that some Allen Bradley PLCs may require additional configuration to be able to communicate over Ethernet. Be sure to consult the instruction manual for your specific PLC to ensure that you're following the correct setup procedure.

Be sure to consult the instruction manual for your specific PLC and use the appropriate software such as RSLinx Classic to communicate with the PLC.
