diCon - Decentralized Intelligent ControllingdiCon - Decentralized Intelligent Controlling

Decentralization means to control where the neces-sity exists to control. In other words direct links are allowed between the individual isolated controllers. All the same it must be possible regardless of distrib- uted isolated controllers to centrally produce and supervise the operational sequence functions. Also service and maintenance interventions must be cen- trally feasible to enable an uniform remote mainte- nance. Finally it applies to avoid communication losses and have operation functions worked out by those who know the process best and to have the documentation always updated and at central dis- posal without paper. Now there is a solution that satisfies these require- ments. The new decentralized automation system "diCon" from Wöhrle.Main part of the new system is a comprehensivemodular automation software. The software runs on an industrial PC that is integrated best in central place to the decentralized automation system. Starting from the configuration the IPC can be sim- ply equipped compared with others since the actual process functions are realized within the distributed intelligent nodes (diNo). The nodes are made of a computer unit, a communi- cation section as field bus interface and an input- output unit. The field bus connection between the intelligent nodes and the industrial PC is worked out for multimaster purposes. This is why the individual nodes are able to communicate with each other and the industrial PC.During current operation only the functions - visual-ization, diagnostic analysis, after-sales service and if requested even the remote maintenance are left to the industrial PC. If the user wanted to do without these functions the IPC could be uncoupled from the network since the network of the intelligent nodes operates independently. But at permanent connection of the industrial PC to the network, the automation system can be involved to the internet or intranet by use of the IPC. In this way a composition of automation systems can be realized between one or even several factories and enable a throughout remote maintenance service. Systeme 13
