Allen-Bradley PLC Tag Client Source Code Stack

The Best Way to Move Data Directly into the Tags of Your PLC

Allen-Bradley programmable controllers supporting EtherNet/IP are prevalent in manufacturing operations worldwide. They manage conveyor lines, water treatment plants, breweries and every other kind of industrial environment imaginable.

But with their Tag-based architecture, accessing the data tables of ControlLogix, CompactLogix, MicroLogix, and PLC5/05 controllers is complicated and time consuming. Not only must you manage long ASCII string names, but the command sets to access these advanced controllers are equally daunting.

Today you have a unique, easy-to-use, royalty-free, ANSI C source code communication stack that does nothing other than read and write tags from the data table of a PLC.

It handles the low-level TCP connections, the EtherNet/IP session layer communications and everything else that you don’t care or need to know about. All you need to do is give your Tag Client-enabled device an Ethernet TCP/IP Address. Then, input the tag names to read from and the tag names to write to. It’s that easy! Data is flowing directly from the tags in the data table of your Allen-Bradley PLC.

The Real Time Automation EtherNet/IP Allen-Bradley PLC Tag Client Source Code Stack offers the quickest method of integrating a ControlLogix, CompactLogix, MicroLogix or SLC5/05 programmable controller into your application.

The Simple Facts

This product is a royalty-free, ANSI C source code that moves data between an Allen-Bradley PLC and an embedded system running Windows, Linux, VxWorks or any other OS.

With this development kit you can do the following.
• Read or Write Allen-Bradley PLC Tags from your Windows PC
• Read or Write Allen-Bradley PLC Tags from your Linux embedded controller
• Read or Write Allen-Bradley PLC Tags from your VxWorks embedded controller
• Read or Write Allen-Bradley PLC Tags from other embedded controllers

This is how you use the software.
• Make a function call to open a connection to the Allen-Bradley programmable controller
• Fill a structure with the list of tags to read or write from your PLC data table
• Make a function call to send that list to the PLC
• Wait for a call back with the results

Taking The First Step

You need to connect to an Allen-Bradley PLC but probably don’t know much about how to do it and certainly don’t have a year or more to properly code it in-house, deploy it and ring it out in 10 or 20 prototype systems. You make devices that do all kinds of wonderful things but you’re not an industrial networking expert nor should you be. That’s where we come in. Our only business is helping automation people just like you get network enabled. It is all we’ve been doing for more than 30 years.

What You’re Going to Get

Out of the box you’ll not only get the Tag Client source code but a working Windows project that you can use to test it, the interface for many TCP/IP stacks, and an extensive user manual. Some folks have been able to take this tool and get messaging working within a few hours!

OK, Why Real Time Automation?

Real Time Automation is your best solution for helping you communicate with an Allen-Bradley PLC. This EtherNet/IP royalty-free source code stack is a single task solution for EtherNet/IP. This solution was built from the ground up specifically for embedded microcontroller applications. It has an incredibly straight forward, easy to understand API that makes integration of EtherNet/IP into your device almost effortless.

The support and responsiveness of our support team is second to none. You receive support from the engineers who wrote the code and sit on the committees that define it. When you call RTA, won’t get an automated voice or redirected to India. You get a live, industry recognized EtherNet/IP expert. That is the RTA difference.
