The Royalty Free Modbus RTU Source Code development kit is the simplest and easiest way to connect your automation device to Modbus RTU Servers like valves, meters, barcode readers and other devices from companies like Groupe Schneider and Rockwell Automation. With a simple architecture and implementation, you can be Modbus RTU enabled in one day. With your royalty free Modbus RTU license, you can ship unlimited binaries and never pay another dollar.

Why Modbus RTU?
The simple architecture and function code interface of Modbus RTU makes it the most common network in North America. It is supported and implemented in the majority of industrial automation networks in North America. To effectively sell your device into a massive market, you need to be Modbus RTU enabled.

How Do You Get Modbus RTU enabled?
The kit provides you with the encoding/decoding, transport and the required application layer interfaces. Your application controls what Modbus RTU data you read and write in the Modbus RTU Servers and how you link that data (16-bit unsigned registers and 1-bit coils) to your internal data space, allowing you to modify or extend your Modbus RTU data implementation without outside assistance.

Real Time Automation supports many operating systems, but here are a few that are the most common:

  • Windows
  • VxWorks
  • Net Silicon
  • Rabbit
  • Quadros
  • Netburner
  • Freescale
  • Linux
  • Mentor Nucleus
  • Open TCP
  • Microchip
  • PowerQUICC II Pro

What’s Included In The Development Kit?
The Real Time Automation Royalty Free Modbus RTU Development Kit includes the No Royalty Source Code license, support for the most implemented Modbus RTU functions, single-task source code, a ready-to-run sample application, complete documentation and much more.

When you purchase the Modbus RTU Client Source Code, you get a product developed with more than 3,000 hours of engineering time. This is a solution that has been used in everything from barcode readers to valve controllers to PLCs and HMIs. This software package is reliable and thoroughly tested in demanding industrial applications.

What Is the Modbus RTU Development Kit?
The Modbus RTU Client Development Kit provides the software required to implement the Modbus RTU Client Protocol. A device with this software can read and write Registers and Coils in Modbus RTU Server Devices. The development kit is a collection of “C” source files. These source files encode Modbus RTU messages and decode responses from Modbus RTU Server devices. The software requires access to a UART and functions to read, write and check the UART status. It also requires a timer tick that it can use to implement the serial communications timeout.

Why Use a Real Time Automation Source Code Development Kit?
You have many alternatives for getting connected to a Modbus RTU Network. There are other vendors selling toolkits and open source solutions that you can use. You can use any of these solutions to Modbus RTU enable your device but there is no other alternative like RTA. With the RTA Development kits you get a solution 100% written in-house by RTA. You can work with the Modbus RTU experts that wrote the code.You’ll get a solution designed specifically for embedded microcontrollers. You’ll be supported from day 1 all the way through the optional conformance testing and beyond.

Is This Really Royalty Free?
Yes, there are no ongoing costs other than an optional maintenance program and your optional subscription to the Modbus IDA Organization.

What is the development process?
The process begins with a detailed walk through once you’ve received the source code and a joint meeting to design the application interface that meets your application requirements. You can get as much or as little assistance as you desire. For more information on the process contact one of the RTA Application Engineers by clicking Contact Us at the top of the page.

What to Do Next
Your next step is to contact the RTA Project Manager and schedule a telephone consultation to discuss your application.
