Using the MicroLogix 1400′s LCD To Set Its IP Address

The MicroLogix 1400’s LCD, unlike the MicroLogix 1100’s, can be used to set the unit’s IP Address.

In today’s article we’ll show you the steps to do just that.

Setting the IP Address of a MicroLogix 1400 using the built-in LCD:

1) When the MicroLogix 1400 is powered on, it displays the I/O Status screen as shown below:

2) To set 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 menu below:

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 press the down arrow button once to select IP Address and press the OK button.

6) To enter the Ethernet Setup you must provide the password t. However if the unit is new, or no password has been set, you can press the OK button to bypass this screen.

7) New MicroLogix 1400’s come setup to automatically obtain an IP Address using BOOT-P, as shown below:

8) To manually assign an IP Address, press the Down Arrow button twice to change the ENET Mode option to “static,” and then press the OK button.

NOTE: The display will not show a message stating that for this change to take effect the Micro will need to be power cycled. We will do this after entering our IP Address.

9) You can now use the Arrow buttons to change the IP Address to your desired value. When done, press the OK button.

10) Now use the Arrow buttons to change the Subnet Mask Address to your desired value. When done, press the OK button.

11) If you wish to enter a Gateway address, use the Arrow buttons to change the address to your desired value. When done, press the OK button.

12) If you wish to enter a Primary DNS address, use the Arrow buttons to change the address to your desired value. When done, press the OK button.

13) If you wish to enter a Secondary DNS address, use the Arrow buttons to change the address to your desired value. When done, press the OK button.

14) Now you’re finished setting up the MicroLogix 1400’s IP Address. As noted above, for the changes to take place you will need to cycle power to your Micro.

15) If you prefer 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 set a MicroLogix 1400’s IP address using the LCD was helpful.
