OBJECTS & FEATURES SUPPORTED
BENEFITS
SUPPORTED OPERATING SYSTEMS

The royalty-free Modbus RTU Server Source Code Stack development kit is the simplest and easiest way to connect your automation device from PCs or PLCs (from companies like Groupe Schneider and Rockwell Automation) to Modbus RTU clients. You can be Modbus RTU-enabled in one day for simple devices with little data, like a valve controller, or several days for a sophisticated device with many registers and coils, like a motor drive. 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 industrial 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 that 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. You provide the mapping from the Modbus RTU data encoding (16-bit unsigned registers and 1-bit coils) to your internal data encoding. This allows you to modify or extend your Modbus RTU data model without outside assistance.

The Key to Integrating Modbus RTU Correctly

The most critical step in your integration is creating an effective Modbus RTU address space. You understand your device, its capabilities and data. The Modbus RTU experts at RTA understand how engineers use Modbus RTU clients to access Modbus RTU server devices. You can get expert assistance in building an address space that meets your customers’ expectations for reliability, functionality and ease-of-use.

What Is the Modbus RTU Development Kit?

The Modbus RTU Server Source Code Stack development kit provides the software required to implement the Modbus RTU server 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-coded source files. These source files encode Modbus RTU messages and decode responses from Modbus RTU server devices. The software requires access to an RTU/IP socket and functions to read, write and check the socket. 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 to Modbus RTU-enable your device but there is no other alternative like RTA.

You’ll get a solution designed specifically for embedded microcontrollers. The RTA development kits are 100% written in-house by RTA, so if you need support, you can work with the Modbus RTU experts who actually wrote the code. And you’ll be supported from day 1 all the way through the optional conformance testing and beyond.

Is It 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 receive the source code followed by 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.

What our Customers are Saying

“When it came to getting the job done, we turned to Real Time Automation, and they performed. RTA helped us figure out a complex communications interface problem in short order, and provided hardware and software modification requirements for implementation before we even got off the plane!”

Kevin L. / HTS Engineering Ltd.

“We have worked with Real Time Automation on a variety of projects over the past few years. I have consistently found them enthusiastic to work with us throughout the development process to ensure that we receive a communications solution that meets our needs. More importantly, their commitment to providing timely support services after the initial release of the system is truly exemplary.”
