Support for the HART DD-IDE has ended. Please refer to the FDI-IDE Tools.

To productively develop your DD you need the DD-IDE. This tool was designed using the accumulated DD Development knowledge of experienced FieldComm Group engineers. This know-how was learned through years of writing DDs, teaching DD Developers and providing technical support to DD Developers worldwide. The DD-IDE tools are designed to allow you to develop a powerful, yet portable, host-independent DD. 

The DD-IDE provides all the tools required to develop and test a DD for your field device. The DD-IDE tools:

  • are integrated in a single environment to automate repetitive tasks; 
  • provide wizards to simplify generation of standard constructs; 
  • support testing and debugging of the DD; and 
  • allow for regression testing and validation of the DD. 

A DD is best developed incrementally. This allows the device capabilities to be modeled and confirmed in small manageable chunks. For example, most DD developers incorporate support for the Universal Commands and a simple set of menus first. Then, Common Practice Commands are added and tested one at a time followed by Device Specific Commands.


This results in an Edit-Build-Test-Validate cycle that is repeated many times. The DD-IDE provides tools for each step in this cycle including:

  • Edit - Central to the DD-IDE is a powerful DDL knowledgeable editor with wizards and project management capabilities. 
  • Build - Tokenizer and DD Management tools are provided. 
  • Test - The SDC-625 Reference DD Host is provided to facilitate testing of the DD.   
  • Validate - Tools are provided to facilitate validation of the DD. This includes Xmtr-DD that allows you to simulate your device and produce abnormal behavior for testing your DD.


  • DD-aware editor with keyword coloring 
  • Supports rapid browsing and navigation of DD source code. 
  • Wizards that simplify creation of DD objects 
  • Integrated support for Tokenizing, Building, Simulating and Executing the DD 
  • Faster, more stable Tokenizer supporting HART 7, SDC-625, HC-475, AMS 6.x 
  • SDC-625 for DD testing, field device communication/configuration ยท 
  • SDC-625 talks to: a simulated device (with Xmtr-DD), a single live field device, or a network of devices (using the HART Server) 
  • Xmtr-DD allowing DD development before field device hardware is available. Supports use of DDL for device and product requirements planning 
  • Communication log assists in DD testing and debug. 

The DD-IDE requires a license fee. The license fee became necessary because of the use of a commercial code editor in the DD-IDE and to provide support for additional tokenizer enhancements

The DD-IDE has a one time license fee and an annual support fee thereafter. The license is for a single developer (named user).

DD Editor and IDE

  • Major productivity gains can be realized with a DD-aware editing environment.
  • Language specific support that has been available for other programming languages (e.g., C, C++) is now available for DDL.
  • DDL syntax is understood by the editor and keywords are highlighted.
  • DD-Edit helps you navigate the DD and jump directly to the definition variables, menus, commands etc.
  • There are also templates that allow new DD objects to be rapidly entered.
