The prerequisite for this is the existence of very well defined execution semantics, such as the ones of Harel Statecharts [ 21 ]. The current version is Both activation mechanisms are supported by IEC 61131- the use of the task, which is one of its execution control elements.

Presence or absence of events does not influence the invocation. Would you like to change to the site? Declaration and initialization of variables.

This discussion raises many questions about the effectiveness of the IEC regarding the features mentioned in [ 1 ]. Deterministic is a computation situation in which the execution time of an action sequence is known precisely [ 23 ]. As capital projects grew The IEC standard has been adopted by the industry and is widely used by control engineers in specifying the software part of systems in the industrial automation domain. The head is connected to the event flows and the body to the data flows.

Portability is a feature that can be considered before and after deployment. You may find similar items within these categories by selecting from the choices below:. IEC programming model There are other bodies that have developed their own industry related standards, but these do not generally go into the same prescriptive depth as IEC and tend to be more application specific.

Industry is looking for mature and stable technologies that will address new requirements, and IEC currently fails in several aspects to this direction, as it is claimed in this paper. It is also claimed that any attempt not only to use the IEC in model-driven engineering, but also to extend it to provide full support for OO should be based on the OO view of the existing eic.

Background and State of the Art Software for controlling industrial processes or machines is commonly executed on Programmable Logic Controllers PLCswhich are digital computers specifically designed for the use in industrial environments, that is, environments with extended temperature ranges and high electrical noise and vibrations. Withoutabox Submit to Film Festivals. The specification of such environments is beyond the scope of this part; however, such an environment shall be capable of producing textual or graphic program documentation in the formats specified in this part.

Example implementations based on the event-driven paradigm are described in [ 2426 ].

It is claimed in [ 1 ] that one of the main features of IEC is the duality of the FB language construct. Also, configuration elements are defined which support the installation of 61113-4 controller programs into programmable controller systems.
