OPC-10000-3 – OPC Unified Architecture - Part 3: Address Space Model

5.6.2 Variable NodeClass

FALSE indicates the Server is not actively collecting data. Default value is FALSE. AccessLevelEx O AccessLevelExType The AccessLevelEx Attribute is used to indicate how the Value of a Variable ... accessed (read/write), if it contains current and/or historic data and its atomicity. The AccessLevelEx does not take any user access rights into account, i.e. although the Variable is writeable this
