12.1 Safety policy ToC Previous Next

In order to prevent and protect the manufacturers and vendors of OPC UA Safety products from possibly misleading understandings or wrong expectations and gross negligence actions regarding safety-related developments and applications the following items must be observed and explained in each training, seminar, workshop and consultancy.

  • Any device will not be automatically applicable for safety-related applications just by implementing OPC UA Safety.
  • In contrast, appropriate development processes according to safety standards must be observed for safety-related products (see IEC 61508, IEC 61511, IEC 602041, IEC 62061, and ISO 13849-2) and/or an assessment from a notified assessment body is required.
  • The manufacturer of a safety product is responsible for the correct implementation of the safety communication layer technology, as well as the correctness and completeness of the product documentation and information.
  • Additional important information including corrigenda and errata published by the OPC Foundation and/or PI must be considered for implementation and assessment.
  • The OPC Foundation will publish an automated test tool which must be used for verification. The test implements the OPC UA Safety test specification described in a separate document. For an overview, see Clause 12.3. The test must be successfully run at a test laboratory accredited by the OPC UA or PI.
