uSimulate HART is an integrated system comprising of hardware and software that is capable of simulating HART devices. HART simulator replaces the field devices, allowing the manufacturers to expedite the developmental and testing phase. The simulator plays a vital role in the verification of HOST Systems such as DCS, AMS, calibrators, configurators, operator training, diagnostics as well as testing, analytical and advisory systems.



  • The simulator brings the possibility of simulating conditions that otherwise are near impossible or impractical with real devices
  • uSimulate HART potentially eliminates the capex required for building the infrastructure to create real world situations
  • A single simulator can simulate different versions of devices and models, which is cost effective when compared to procuring all variations and models of the real devices
  • An effective tool for interoperability testing that eliminates the possibility of damaging real devices while creating outlier conditions
  • Extreme conditions that have the potential to damage the real devices and could be a safety hazard for the operator can be simulated as seen by the controller
  • An effective investment for verification of host systems such as DCS, AMS, calibrators, configurators, operator training, diagnostics as well as verifying the analytical and advisory systems


  • uSimulate HART is used in applications for product engineering, system engineering, commissioning, support, training and product demonstrations
  • The application provides immense value to OEM, SI, R&D and educational institutions for use in various applications
  • Verification of control systems, AMS systems, configurators, calibrators, diagnostic / test and measurement equipments


uSimulate HART displays the following features to simulate the actual field conditions seen in the slave devices. It incorporates a simple and intuitive user access control for the web application to provide access to all of the simulator’s features.

  • Each slave device data can be configured for its variables and commands, using the web application
  • Can simulate slave devices having a combination of HART protocol revision 5, 6, 7. Simulates single or multiple HART slave devices simultaneously (depends on the configuration)
  • All Universal commands are supported as per HART specification
  • All channels are loop powered
  • Configuration of the commonly supported practice commands in slave devices is possible
  • Provides channel to channel isolation
  • Each channel can be configured as either analog input or analog output device
  • Four variables (PV, SV, QV, and TV) can be configured for each device
  • Variable data is simulated in various patterns (Linear, sinusoidal, constant, unit step, random) with applicable lower and upper limits
  • Alarm bits in command 48 can be configured
  • The web application generates and displays logs to monitor the data flow and to identify any error conditions during simulation
  • Can run the preconfigured simulations programmatically. This is especially useful for automated testing and CI/CD
