Finding a MicroLogix 1100's IP and MAC Address



The MicroLogix 1100 includes an Ethernet port with a fixed MAC address, as well as a settable Ethernet IP address. In today's article we'll show you how to find both.

Finding the MAC address on a MicroLogix 1100:

1) Thankfully, each MicroLogix 1100 comes with it's unique MAC address stenciled on it. To find it, remove the battery compartment cover on the right side of the Micro:

MicroLogix-1100-MAC-IP-Location

2) At the very bottom of the compartment, directly under the battery plug, you will see the MicroLogix 1100 MAC address. . The MAC Address of the unit pictured below is: 00:0F:73:00:23:26
MicroLogix-1100-MAC

Finding the IP and MAC address of a MicroLogix 1100 using the built-in LCD:

1) When the MicroLogix 1100 is powered on, it displays the I/O Status screen as shown below:

MicroLogix-1100-LCD-Home-IO-Status

2) To find the Micro's IP and MAC address using the LCD,  we need to access it's menu. To do this, press the ESC button and you should see the display below:

MicroLogix-1100-LCD-Menu

3) Next, press the down arrow button four times to select “Advanced Set,” then press the OK button:

4) Here, press the down arrow button twice to select “ENET CFG,” then press the OK button:

5) Now you will see displayed the MAC address followed by the IP address of your MicroLogix 1100.

6) To return to the I/O Status display, press the ESC button until you see the main menu, and then select “I/O Status” and press the OK button:

I hope the above procedure on how to find a MicroLogix 1100's IP and MAC address was helpful.
