The IEC 61499 gives developers considerable freedom and offers several features that support reuse. Although this can help the adoption of the standard into an organization's development process, the range of design decisions can also harm the reusability of software, if components are developed with incompatible design principles. Guidelines are needed, but the unique backgrounds and market positions...
This article summarizes the requirements for communication redundancy in the different market sectors for industrial automation. It reviews the different solutions for using standard Ethernet to fulfill requirements and proposes more special extensions to Ethernet to obtain this. The path forward is sketched. Focus is on ideas and concerns that must be taken when the standardization work of IEC in...
Information system security for industrial plants is a topic of increasing importance. Effective and cost-efficient security solutions require some kind of industry consensus or standardization. This paper examines the interests of the various stakeholders in the industrial security field (e.g. society, plant owners, service providers, automation vendors, and consultants) and evaluates some of the...
The current situation in automation is characterised by an ongoing trend towards distributed systems based on intelligent devices, the application of Web services and the usage of Ethernet as the main communication media. The most important standard to deal with distributed control systems (DCSs) is the IEC 61499 whose industrial application is still at the beginning. Within this paper, a platform...
Industrial automation is currently on the cusp to the application of distributed systems based on distributed intelligence enabling distributed decision making within control. As one main technology within this field IEC 61499 based function block systems would be applied. But the usage of function block systems may cause problems which have to be avoided prior to the integration of a function block...
The IEC 61499 (function block) standard proposes an open architecture for distributed industrial-process measurement and control systems (IPMCS). The IEC 61499 defines the basic concepts and methodology for the design of modular reusable distributable systems, and paves the way for the new reconfigurable and flexible manufacturing. This paper presents the development of a software tool (IEC 61499...
The paper presents a modular control model to develop the control functions for manufacturing systems and its implementation using IEC 61499 function blocks. In particular, a new control module for automation objects is formally specified and its use on a hierarchical functional architecture has been discussed and the possible distribution of its IEC 61499 implementation is investigated. Finally,...
A considerable share of power drive systems (PDS) on the market are controlled over industrial networks or fieldbuses. These interfaces are defined in a manufacturer independent way in profiles, which are dependent of the type of network interface. A generic interface to PDS opens the possibility to accept these profiles in international standards and to open the access for new, industrial Ethernet...
