AutomationML (Automation Markup Language) is a neutral data format based on XML for the storage and exchange of plant engineering information, which is provided as an open standard. The goal of AutomationML is to interconnect the heterogeneous tool landscape of modern engineering tools in their different disciplines, e.g. mechanical plant engineering, electrical design, HMI development, PLC and robot control.

Approach

AutomationML describes real plant components as objects encapsulating different aspects. An object can consist out of other sub-objects, and can itself be part of a bigger composition. It can describe a screw, a claw, a robot or a complete manufacturing cell in different levels of detail. Typical objects in plant automation comprise information about topology, geometry, kinematics and logic, where logic comprises sequencing, behaviour and control.

AutomationML incorporates different standards through strongly typed links across the formats:

  1. Topology implemented with CAEX (IEC 62424)
    Properties and relations of objects in their hierarchical structure
  2. Geometry implemented with COLLADA of the Khronos Group
    Graphical attributes and 3D information
  3. Kinematics implemented with COLLADA
    Connections and dependencies among objects to support motion planning
  4. Logic implemented with PLCopen XML
    Sequences of actions, internal behavior of objects and I/O connections

For future extensions, AutomationML is designed to integrate further formats using the same referencing mechanism.

History

After first evaluations of exchange formats, Daimler initiated the joint activity of the companies ABB, KUKA, Rockwell Automation and Siemens together with netAllied and Zühlke as well as the Karlsruhe Institute of Technology (KIT) and the University of Magdeburg in October 2006 to define and standardize the Automation Markup Language (AutomationML) as an intermediate format for the Digital Factory. In April 2009, an independent organization was founded. The Fraunhofer IOSB institute became the first new member. AutomationML is available as open standard free of charge.

Standard Generalized Markup Language Markup language

The Standard Generalized Markup Language is a standard for defining generalized markup languages for documents. ISO 8879 Annex A.1 states that generalized markup is "based on two postulates":

XML Markup language developed by the W3C for encoding of data

Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The World Wide Web Consortium's XML 1.0 Specification of 1998 and several other related specifications—all of them free open standards—define XML.

The XML Metadata Interchange (XMI) is an Object Management Group (OMG) standard for exchanging metadata information via Extensible Markup Language (XML).

The Organization for the Advancement of Structured Information Standards is a global nonprofit consortium that works on the development, convergence, and adoption of open standards for cybersecurity, blockchain, Internet of Things (IoT), emergency management, cloud computing, legal data exchange, energy, content technologies, and other areas.

Geography Markup Language Used to describe geographical features

The Geography Markup Language (GML) is the XML grammar defined by the Open Geospatial Consortium (OGC) to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. Key to GML's utility is its ability to integrate all forms of geographic information, including not only conventional "vector" or discrete objects, but coverages and sensor data.

Chemical Markup Language is an approach to managing molecular information using tools such as XML and Java. It was the first domain specific implementation based strictly on XML, first based on a DTD and later on an XML Schema, the most robust and widely used system for precise information management in many areas. It has been developed over more than a decade by Murray-Rust, Rzepa and others and has been tested in many areas and on a variety of machines.

ISO 10303 is an ISO standard for the computer-interpretable representation and exchange of product manufacturing information. Its official title is: Automation systems and integration — Product data representation and exchange. It is known informally as "STEP", which stands for "STandard for the Exchange of Product model data". ISO 10303 can represent 3D objects in Computer-aided design (CAD) and related information.

COLLADA is an interchange file format for interactive 3D applications. It is managed by the nonprofit technology consortium, the Khronos Group, and has been adopted by ISO as a publicly available specification, ISO/PAS 17506.

A user interface markup language is a markup language that renders and describes graphical user interfaces and controls. Many of these markup languages are dialects of XML and are dependent upon a pre-existing scripting language engine, usually a JavaScript engine, for rendering of controls and extra scriptability.

Profinet

Profinet is an industry technical standard for data communication over Industrial Ethernet, designed for collecting data from, and controlling equipment in industrial systems, with a particular strength in delivering data under tight time constraints. The standard is maintained and supported by Profibus & Profinet International, an umbrella organization headquartered in Karlsruhe, Germany.

The international standard IEC 61499, addressing the topic of function blocks for industrial process measurement and control systems, was initially published in 2005. The specification of IEC 61499 defines a generic model for distributed control systems and is based on the IEC 61131 standard. The concepts of IEC 61499 are also explained by Lewis and Zoitl as well as Vyatkin.

The ISO 15926 is a standard for data integration, sharing, exchange, and hand-over between computer systems.

CAEX is a neutral data format that allows storage of hierarchical object information, e.g. the hierarchical architecture of a plant. On a certain abstraction level, a plant consists of modules or components that are interconnected. CAEX allows storage of those modules or components by means of objects. Object oriented concepts such as encapsulation, classes, class libraries, instances, instance hierarchies, inheritance, relations, attributes and interfaces are explicitly supported. CAEX bases on XML and is defined as an XML schema. The original intention of developing CAEX was to remedy industry's lack of a common and established data exchange between process engineering tools and process control engineering tools. However, CAEX can be applied to all types of static object information, e.g. plant topologies, document topologies, product topologies, petri nets. It can also be used for non-technical applications like phylogenetic trees.

CODESYS

Codesys is a development environment for programming controller applications according to the international industrial standard IEC 61131-3. The main product of the software suite is the CODESYS Development System, an IEC 61131-3 tool.

The Office Open XML file formats are a set of file formats that can be used to represent electronic office documents. There are formats for word processing documents, spreadsheets and presentations as well as specific formats for material such as mathematical formulae, graphics, bibliographies etc.

NeuroML is an XML based model description language that aims to provide a common data format for defining and exchanging models in computational neuroscience. The focus of NeuroML is on models which are based on the biophysical and anatomical properties of real neurons.

PLCopen is an independent organisation providing efficiency in industrial automation based on the needs of users. PLCopen members have concentrated on technical specifications around IEC 61131-3, creating specifications and implementations in order to reduce cost in industrial engineering. The outcome for example is standardized libraries for different application fields, harmonized language conformity levels and engineering interfaces for exchange. Experts of the PLCopen members are organized in technical committees and together with end users define such open standards.
