Abstract

IEC 62541-6:2015 specifies the OPC Unified Architecture (OPC UA) mapping between the security model described in IEC TR 62541-2, the abstract service definitions, described in IEC 62541-4, the data structures defined in IEC 62541-5 and the physical network protocols that can be used to implement the OPC UA specification. This second edition cancels and replaces the first edition published in 2011 and constitutes a technical revision. This edition includes the following changes: - A new HTTPS transport has been defined; - Added an additional padding byte to handle asymmetric key sizes larger than 2048 bits. Fixed errors in SOAP action URIs; - Needed a standard way to serialize nodes in an address space. Added the UANodeSet schema defined in Annex F.
