The EU funded project VAN targets the only partially existing proprietary solutions to connect automation networks and devices via public networks in a secure, safe and predictable way. This work in progress paper provides an overview of the solutions implemented in VAN which are currently evaluated for the use in general purpose networks. The generally accepted phase model to implement an abstract...
This contribution investigates the topic ldquovirtual commissioningrdquo from an industrial point of view and proposes an evolutionary and realistic technical concept for the introduction of virtual commissioning environments. Main points of this paper are the identification and formulation of industrial requirements for the introduction of a virtual commissioning environment, a proof of commercial...
Embedded systems rapidly grow in several dimensions. They grow in size, from local isolated networks with simple protocols to network hierarchies to large open heterogeneous networks with complex communication behaviour. They grow in performance, from simple microcontrollers to superscalar to multicore systems with many levels of memory hierarchy. And, they expand in the time dimension by moving from...
An industrial application can easily require many thousands of cables to connect sensors and actuators to the control system. These connections are fixed multi core cables, fitted with either a plug or with terminals. Besides the cost of laying all of these and the risk of wiring errors, subsequent changes to the setup may require large parts of the factory floor to be rewired. Additionally, where...
Real leak signals, acquired in industrial pipeline systems may manifest two typical non stationary signatures, due to the disturbing noise: abrupt amplitude random changes on one side and a time varying mean on the other side. This paper proposes a pre-processing algorithm for extracting stationary information from the received signals, in order to improve the leak location on the pipe. This method...
Mechatronics is defined as “Synergetic Integration of Mechanics and Electronics”. Recently computer and information technologies have accelerated mechatronics technology to be more and more intelligent. Thus, intelligent mechatronics is a technology on how to give human psychology to mechanical system so that human and mechanical system could interact with each other.
The SARBAU project is a study on a highly self configuring building automation and control network using IP as field level protocol. UPnP is used for device operation and control. The SARBAU concept covers the use cases initial setup, commissioning, operation, and retrofit. Group address agents are employed to reduce load on the devices and control points for collaborative commands. For evaluation...
The rise of Industrial Ethernet as network technology for Distributed Automation Systems introduces the need for migration strategies from field bus based systems towards this new technology. This paper discusses the problem of acquiring and translating the information needed for the setup of a PROFINET/PROFIBUS proxy as an example for a migration solution. The diverse technologies defined for device...
The different aspects that need to be tackled in order to develop automation for machines and plants through reusing tested modules will be discussed. The development of such modules involves all disciplines and their specific variations and version management, as well as the dependencies between those variations. Version management is needed to track modifications of these different modules. Variations...
The philosophy of Kanban is that parts and materials should be supplied at the very moment they are needed in the factory manufacturing process. e-based inter-enterprise supply chain Kanban are investigated on the distribution center of a global supply chain network, with information technology based pull systems being examined from the distributors back to the suppliers. Using the qualitative case...
The dater equalities constitute a well-known tool which allows the description of timed event graphs in the field of (max, +) algebra. This paper gives an equivalent model in the standard algebra which can describe timed event graphs with inputs and outputs. Concepts of componentwise order and monotone inequalities prove the existence of unique minimum, or maximum, solution in special system Ax les...
In the ldquodigital factoryrdquo tool chain, usually only the nominal production sequence, i.e. the production process under ideal conditions, is considered and automatically converted into PLC code. However, the nominal sequence is a prominent but rather small fraction of the total PLC code. The large remaining parts, such as interlock logic, safety functions, start-up and shutdown sequences, are...
