OPC UNIFIED ARCHITECTURE –

Part 11: Historical Access

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62541-11 has been prepared by subcommittee 65E: Devices and
integration in enterprise systems, of IEC technical committee 65: Industrial-process
measurement, control and automation.
The text of this standard is based on the following documents:
CDV Report on voting
65E/380/CDV 65E/410/RVC

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

OPC UNIFIED ARCHITECTURE –

Part 11: Historical Access



1 Scope
This part of IEC 62541 is part of the overall OPC Unified Architecture standard series and
defines the information model associated with Historical Access (HA). It particularly includes
additional and complementary descriptions of the NodeClasses and Attributes needed for
Historical Access, additional standard Properties, and other information and behaviour.
The complete AddressSpace Model including all NodeClasses and Attributes is specified in
IEC 62541-3. The predefined Information Model is defined in IEC 62541-5. The Services to
detect and access historical data and events, and description of the ExtensibleParameter
types are specified in IEC 62541-4.
This standard includes functionality to compute and return Aggregates like minimum,
maximum, average etc. The Information Model and the concrete working of Aggregates are
defined in IEC 62541-13.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.

3 Terms, definitions, and abbreviations
3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC TR 62541-1,
IEC 62541-3, IEC 62541-4, and IEC 62541-13 as well as the following apply.
3.1.1
Annotation
metadata associated with an item at a given instance in time
Note 1 to entry: An Annotation is metadata that is associated with an item at a given instance in time. There does
not have to be a value stored at that time.

---------------------- Page: 13 ----------------------

SIST EN 62541-11:2015
– 8 – IEC 62541-11:2015 © IEC 2015
3.1.2
BoundingValues
values associated with the starting and ending time
Note 1 to entry: BoundingValues are the values that are associated with the starting and ending time of a
ProcessingInterval specified when reading from the historian. BoundingValues may be required by Clients to
determine the starting and ending values when requesting raw data over a time range. If a raw data value exists at
the start or end point, it is considered the bounding value even though it is part of the data request. If no raw data
value exists at the start or end point, then the Server will determine the boundary value, which may require data
from a data point outside of the requested range. See 4.4 for details on using BoundingValues.
3.1.3
HistoricalNode
Object, Variable, Property or View in the AddressSpace where a Client can access historical
data or Events
Note 1 to entry: A HistoricalNode is a term used in this document to represent any Object, Variable, Property or
View in the AddressSpace for which a Client may read and/or update historical data or Events. The terms
“HistoricalNode’s history” or “history of a HistoricalNode” will refer to the time series data or Events stored for this
HistoricalNode. The term HistoricalNode refers to both HistoricalDataNodes and HistoricalEventNodes.
3.1.4
HistoricalDataNode
Variable or Property in the AddressSpace where a Client can access historical data
Note 1 to entry: A HistoricalDataNode represents any Variable or Property in the AddressSpace for which a Client
may read and/or update historical data. “HistoricalDataNode’s history” or “history of a HistoricalDataNode” refers to
the time series data stored for this HistoricalNode. Examples of such data are:
• device data (like temperature sensors),
• calculated data,
• status information (open/closed, moving),
• dynamically changing system data (like stock quotes),
• diagnostic data.
The term HistoricalDataNodes is used when referencing aspects of the standard that apply to accessing historical
data only.
3.1.5
HistoricalEventNode
Object or View in the AddressSpace for which a Client can access historical Events
Note 1 to entry: “HistoricalEventNode’s history” or “history of a HistoricalEventNode” refers to the time series
Events stored in some historical system. Examples of such data are:
• Notifications,
• system Alarms,
• operator action Events,
• system triggers (such as
