IEC defines several function block types, all of which can contain a behavior description in terms of service sequences:. CastellanosMarcelo V. IEC enables an application-centric design, in which one or more applications, defined by networks of interconnected function blocks, are created for the whole system and subsequently distributed to the available devices. IEC defines the architecture for distributed systems.
RoopValeriy VyatkinZoran A. This part answered FAQs related to the IEC standard and described the use of IEC elements with examples to solve common challenges during the engineering of automation systems.
This includes requirements for the representation and the portability of IEC elements as well as a DTD format to exchange IEC elements between different software tools. References Publications referenced by this paper. IEC describes the rules that a system, device or software tool stamdard follow to be compliant to IEC In the “System-Level Design for Distributed Automation” section, we give a general introduction to IEC in terms of its value for the automation systems developer.

The event driven execution model allows an explicit specification of the execution order of function blocks. In contrast to IECan IEC interface contains event inputs and outputs in addition to data inputs and outputs.
Among other examples, IEC described the use of SIFBs as communication function blocks for remote access to real-time data and parameters of function blocks; the use of adapter interfaces to implement object oriented concepts; initialization algorithms in function block networks; and the implementation of ECCs for a simplified motor control of hypothetical VCRs.

IEC – International Standard for Distributed Systems
The specification of IEC defines a generic model for distributed control systems and is based on the IEC standard. Through the interface of the software tool and the management commands, online reconfiguration of IEC applications can be realized. These rules are related to interoperability, portability and configuration.
The interoperability between devices of different vendors is defined by the layers of the OSI models. The XML exchange format which determines portability of IEC compliant applications is defined within part 2 and is completed by the compliance profile, for example by declaring the supported file name extensions for exchange of software library elements.
Graph coloring Software development process. The international standard IECaddressing the topic of function blocks for industrial process measurement and control systems, was initially published in IEC compliant runtime environment [Online].

A compliance profile describes how a system conforms to the rules of the IEC standard. For example, the configurability of a device by a software tool is determined by the supported management commands. Automation FB Term Type. Two devices wtandard interoperable if they can work together to provide the functionality specified by a system configuration.
Therefore, applications of a system are distributable but maintained together.
There are already some IEC compliant software tools available. Semantic Scholar estimates that standatd publication has 78 citations based on the available data.
