METHODS FOR PROVIDING AND VALIDATING ALTERNATIVE OBJECT IDENTIFIERS AND FOR DETERMINING REFERENCES OF ALTERNATIVE OBJECT IDENTIFIERS WITHIN AN OPC-UA-BASED COMMUNICATION ENVIRONMENT

摘要

The invention relates to a method for providing alternative object identifiers for objects of an address space of a server (S1, S2) within an OPC-UA-based communication environment (K), wherein each object of the address space of the server (S1, S2) is clearly identified by a conventional object identifier, wherein at least one additional identifier is defined and stored in a register of additional identifiers defined for this address space of the server (S1, S2), and wherein an alternative object identifier also clearly identifying the object is formed for each object of the address space of the server (S1, S2), whereby the additional identifier is combined with the conventional object identifier of the respective object according to a determined system. The invention also relates to a method for validating alternative object identifiers and a method for determining references of object identifiers, as well as a server, a system and a computer program product designed to carry out at least one of the methods.
