Diagnostics according to this document may be implemented in a non-safety-related way. This allows for categorization and localization of safety communication errors.

This document provides two types of diagnostics:

  • Diagnostics messages generated by the SafetyConsumer and provided in a vendor-specific way.
  • The method “ReadSafetyDiagnostics”, defined in the OPC UA Information Model (see and 6.4.3).
