Since this document covers many manufacturing operations and enterprise domains and there are many different standards for those domains, the semantics of this data exchange standard are described at a conceptual level intended to enable the other standards to be mapped to these semantics. To this end, this document defines a set of elements contained in the generic interface, together with a mechanism for extending the interface content for implementations.
The scope is limited to the definition of object models and attributes of the exchanged information defined in the IEC 62264-1.
This third edition cancels and replaces the second edition published in 2013. It is published as a double logo standard. This edition constitutes a technical revision. Due to the extent of the changes and updates, this document cannot ensure backward compatibility to implementations based on older editions. This edition includes the following significant technical changes with respect to the previous edition and ANSI/ISA 95.00.02-2018 (ED3):
a) object models are added for the use of interactive communications to notify subscribers about the occurrence of events and to provide context information about the event, making the information exchange more efficient and consistent. The added object models were the operations event model and operations record model.
b) operations location model and spatial definition attribute added to allow the description of operation locations.
c) operations test model added to define how test specifications and test results are related to testable objects, operations test requirements, actual resource, and work definitions.
d) definition of possible measurement uncertainty sub-attributes for all value, quantity and duration attributes defined in this document.
e) updated hierarchy scope model.
f) removed as separate models in this edition were the models for product definition, production schedule, production performance, and production capability. Their content is covered for all manufacturing operations management categories under operations models.
g) object model was added for the operations segment capability as a collection of resources related to other operations models.
h) updated relationship name and role name conventions established in 3.3.4 and implemented across all models and associated tables.
i) updated all objects’ relationship role table with explicit source and target names.
j) updated common header attributes for objects and property objects established in 4.5 and implemented across all models and associated tables.
k) updated explanation of the ‘relationships between resource reference objects in operations management information models and resource models. These additional resource relationships are added to all operations management models.
l) added an annex explanation for implementation options for specifying values in unit of measurement a
This edition includes the following significant technical changes with respect to the previous edition:
a) addition of "Comment" parameter to Alarm shelving methods;
b) addition of method that allows a client to get the members of a group, since it is possible that the AddressSpace does not expose instances of alarms;
c) addition of deadband properties for all limits in the limit AlarmType (from which all other types described in this issue are derived);
d) addition of text explaining the disabling of alarms is no longer supported in ISA 18.2 and that it is maintained in this document for backward compatibility, but that it is recommended that Alarm not be disabled;
e) addition of optional severities for limit alarms;
f) addition of new AlarmState variable type that can be used to collect alarm information for displays on graphics;
g) addition of SupportsFilterRetain property to improve Client filtering;
h) removal of ConditionSubClassId and ConditionSubClassNames from the conditiontype definition since they are now defined in BaseEventType.
This part of EN 61326 is a product family standard specifying requirements for immunity and emissions regarding electromagnetic compatibility (EMC) for electrical equipment, operating from a supply or battery of less than 1 000 V AC or 1 500 V DC or from the circuit being measured. Equipment intended for professional, industrial-process, industrial-manufacturing and educational use is covered by this part. It includes equipment and computing devices for
— measurement and test;
— control;
— laboratory use;
— accessories intended for use with the above (such as sample handling equipment),
intended to be used in industrial and non-industrial locations.
Computing devices and assemblies and similar equipment within the scope of information technology equipment (ITE) and complying with applicable ITE EMC standards can be used in systems within the scope of this part of IEC 61326 without additional testing, if they are suitable for the intended electromagnetic environment.
It is generally considered that this product family standard takes precedence over the corresponding generic EMC standards.
The following equipment is covered by this document.
a) Electrical measurement and test equipment
This is equipment which, by electrical means, measures, indicates or records one or more electrical or non-electrical quantities, also non-measuring equipment such as signal generators, measurement standards, power supplies and transducers.
b) Electrical control equipment
This is equipment which controls one or more output quantities to specific values, with each value determined by manual settings, by local or remote programming, or by one or more input variables. This includes industrial process measurement and control (IPMC) equipment, which consists of devices such as:
– process controllers and regulators;
– programmable controllers;
– power supply units for equipment and systems (centralized or dedicated);
– analogue/digital indicators and recorders;
– process instrumentation;
– transducers, positioners, intelligent actuators, etc.
c) Electrical LABORATORY equipment, including In Vitro Diagnostic (IVD) medical equipment
This is equipment used to prepare or analyse materials, or measure, indicate or monitor physical quantities. This equipment might also be used in areas other than laboratories.
d) Equipment a), b) or c) as above when being equipped with components having radio functionality, for example for wireless communication.
Equipment within the scope of this document might be operated in different electromagnetic environments; depending on the electromagnetic environment different emission and immunity test requirements are applicable.
This document considers three types of electromagnetic environments:
• BASIC ELECTROMAGNETIC ENVIRONMENT;
• INDUSTRIAL ELECTROMAGNETIC ENVIRONMENT;
• CONTROLLED ELECTROMAGNETIC ENVIRONMENT.
Corresponding immunity test requirements are described in Clause 6.
In terms of emission requirements, equipment shall be classified in Class A or Class B equipment, as per the requirements and procedure of CISPR 11. The corresponding emission requirements are described in Clause 7.
The specified emission and immunity requirements aim at achieving electromagnetic compatibility between equipment covered in this document and other equipment that might operate at locations with electromagnetic environments considered in this document. Guidance for an assessment concerning the risk for achieving EMC is given in Annex B.
