PLC Networking Basics using a Controllogix module also has an associated interactive youtube course that uses an intro project of networking multiple class laptops to a single Controllogix 5000 PLC/PAC. This powerpoint is for reference and additional information to supplement the course at http://www.youtube.com/watch?v=Au03psa9Vxk The PLC Networking Basics course has a total of 4 training modules (videos), each with it's own question at end, before directing you to next Controllogix tutorial. There is also an associated test for this training course at http://bin95.com/Employee-Training-Assessments/PLC-Training-Assessment/PLC-Networking-Basics-Controllogix.php
Hope you like and share, which will encourage us to create more of these free courses.

Editor's Notes
Whenever working with networking Allen Bradley products, it is a good practice to use Octal number system (no 8s or 9s). So you will notice our Laptop station numbering in map above skips number 68 and 69. Also a good idea is to have laptops in a separate group of address than ENBT cards. (As station numbers are just for RSLinx, IP addresses use decimal numbering system.)
Click on task bar and then ControlPanel
Then click ok for this dialog box, and click done button on next dialog box.
At command prompt, type “ping 192.168.1.3” or what ever address you have set up in your ControlLogix program loaded in the processor (via RSLogix 5000) for your ENBT card.
A successful ping will show the same number of packets received as was sent. (our example 4 sent, 4 received). The Average time should be less than 1 millisecond. (our example was <0ms)
If longer time was seen, or packets where lost, try another cable.
Commend prompt = C:DOCUME~1STEVE>
You will find the required EDS files on BIN95.com USB Flash Drive we giveaway in class. (EDS (Electronic Data Sheet)) They will be under the PLC5000 directory
Note: Make sure “Look in subfolder” check box is checked, before clicking “Next button of wizard or it may not find your EDS files. To make it easier, we have placed only the ENBT EDS files in a folder “EDS” on the BIN95.com Flash Drive.
So the step in this slide is to click “Next” button 3 times in a row, once for each of the 3 dialog boxes that appear. Then click “Finish” on the 4th dialog box, then “Exit” on the 5th dialog box. You are done installing EDS files.
Use Station numbers (XX) and IP Addresses you mapped out in slide 1. (The example above is for Student laptop #6 on network map.)
Note: If you see a yellow question mark on the right instead of ENBT icon pictured above, you did not properly install EDS files for ENBT.
Access Wireless router via web browser. Type in original IP address (typically 192.168.0.1) Default user name is typically “admin”, passwords are “password” or “admin”
In the default IP address the “0” (zero) we will refer to as the Channel. The ENBT card and laptops where all set up in previous slides with channel 1 (like 192.168.1.3). So we want to change the Router TCP/IP from 0 to 1 also. So wireless is on same channel.
Also while you are there, double check to make sure mask is the same as it was for ENBT card and laptops (255.255.255.0) Changing channel from default can reduce interference, increase speed and make a little more secure. But in an Industrial environment (not a classroom like we are setting up here), you want to use the most secure industrial network, security and protocols you can.
In the Who Active dialog box, click on the “+” sign to the left of ENBT driver icon.
Click on the “+” sign next to 1756-ENBT
Click on the “+” sign next to 1756-A4/A (the rack)
Click on the Icon for 1756-L1/A (Logix 5550 processor)
Click “Go Online” button.
Success !! If you see gears moving in the icon
