Description of BS EN IEC 62541-10:2020 2020IEC 62541-10:2020 is available as IEC 62541-10:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62541-10:2020 defines the information model associated
with Programs in the OPC Unified Architecture. This includes the
description of the NodeClasses, standard Properties, Methods and
Events and associated behaviour and information for Programs. The
complete Address Space model including all NodeClasses and
Attributes is specified in IEC 62541-3. The Services such as those
used to invoke the Methods used to manage Programs are specified in
IEC 62541 4. This third edition cancels and replaces the second
edition published in 2015. This edition includes several
clarifications and in addition the following significant technical
changes with respect to the previous edition: a) Changed
ProgramType to ProgramStateMachineType. This is in line with the
NodeSet (and thus implementations). In ProgramDiagnosticDataType:
changed the definition of lastInputArguments and
lastOutputArguments and added two additional fields for the
argument values. Also changed StatusResult into StatusCode. Created
new version of the type to ProgramDiagnostic2DataType. b) Changed
Optional modelling rule to OptionalPlaceHolder for Program control
Methods. Following the clarification in IEC 62541-3, this now
allows subtypes (or instances) to add arguments.
