This document uses the OPC UA services for connection establishment, it poses no additional requirement to these services.

This version of the document describes configuration only at engineering time. This means that the parameters defined in the SPI (see 6.3.3.3 and 6.3.4.4) are read-only via the interface described in this document. Changing of parameters is expected to be done in a safety-related way, using the respective tools and interfaces provided by the vendor. Future versions of this document may specify a vendor-independent interface for configuration.
