The document provides guidelines for using Allen Bradley products in networking, emphasizing the use of the octal number system for station numbering and separate addressing for laptops and ENBT cards. It outlines steps for pinging devices, installing EDS files from provided flash drives, and configuring default router settings to ensure optimal network performance. Errors during installation and configuration, such as not seeing the ENBT icon properly, are also addressed with recommended troubleshooting actions.
PLC Networking Basics - Instructor's notes
- 1. BIN95.com 1/30/2014 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.) Copyright Business Industrial Network (Trade markes their respective owners) 1

- 8. BIN95.com 1/30/2014 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.

- 16. BIN95.com 1/30/2014 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. Copyright Business Industrial Network (Trade markes their respective owners) 16
- 17. BIN95.com 1/30/2014 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.
