HART Protocol Stack Revision 7.9 – Current HART Software Stack for Field Device Development

MESCO offers a current HART Protocol Stack Revision 7.9 for the development of modern field devices. The stack enables efficient integration of HART communication into customized embedded systems and supports the latest requirements of the FieldComm Group.

Key Benefits of the HART Stack:

• Supports the current HART® Protocol Revision 7.9 – verified with the FieldComm Group Test Suite Rev. 4.0
• All Universal Commands
• Common Practice Commands
• Templates for User-Specific Commands
• Preparation for Non-Volatile Memory (NVM)
• Support for various HART modem devices
• Optimized integration into embedded systems
• Sensor and actuator applications

This enables manufacturers to integrate HART technology quickly and efficiently into existing product platforms.

HART Development for Functionally Safe Transmitters

Combining Safety with Intelligent Diagnostics

MESCO also develops HART solutions for applications involving functional safety.

A proven concept:

• Safety-relevant signal transmission is handled via a suitably designed 4–20 mA interface
• The HART protocol operates as an additional digital communication layer
• Diagnostic and service information can be used without affecting the safety function

Typical applications:

• Safety-related process measurement devices for temperature, level, flow, pressure, analysis, and positioners
• Diagnostic functions for Safety Instrumented Systems (SIS)

MESCO supports manufacturers in implementing suitable system architectures for safe and intelligent field devices.

Device Description and Host Integration

For complete system integration, MESCO develops Device Descriptions based on EDDL technology. Integration is provided for: Siemens PDM, Rosemount AMS, Rosemount Handheld Systems.

HART Pre-Certification and FieldComm Group Testing

Support from Prototype to Certified Product

Successful certification of a HART device requires extensive testing and documentation.

MESCO has an in-house test environment at its Fieldbus Competence Center laboratory for:

• Physical Layer Test – Testing the electrical characteristics and signal quality of the HART interface
• Data Link Layer Test – Validation of communication mechanisms and protocol sequences
• Application Layer Test – Verification of device functions and HART command structures

Support with FieldComm Group Certification

MESCO supports you throughout the entire certification process. With this support, device manufacturers can reduce development risks and significantly shorten the time-to-market for their HART devices.
