NE107 “Self-monitoring and diagnostics of field devices” has been revised

Abstract to NE 107 “Self-monitoring and diagnostics of field devices”
(Edition: 2025-07-15)

The NE107 defines standards for self-monitoring and diagnostics of field devices in process industries, establishing four key status signals: Failure (F), Function check (C), Out of specification (S), and Maintenance request (M).

Field device diagnostics aim to provide reliable information about device conditions so users can take appropriate actions.

This document specifies standardized visual representations for status signals, including color-coding and symbols for graphical interfaces and LED indicators, to ensure consistent communication across different systems and interfaces.
NE107 serves as a basis for transmitting diagnostic information according to the NOA information model and describes basic requirements for transmitting device status of sensors.

The annexes provide detailed listings of application-specific faults and fault conditions for various field device types, including their relative priority from the user's perspective, though the technical feasibility of diagnosing these faults is not considered in the recommendation.
