6 Issue 3 Technical specifications Process Plant for Dairy Products (LE00) a) EDIBON Scada Net System technical specifications - ESN system introduction: EDIBON SCADA NET (ESN) System reproduces an integrated model plant (CIM model) which defines the various levels of communication: Management design level: orientated towards production management, this level requires the installation of networks, which can handle a large amount of traffic with no restrictions on response time. Local area networks adapted for this level are based on an Ethernet architecture. Factory floor level: factory floors, which are made up of cells, exchange data and can therefore monitor production. At this level the data rate of the network must be high enough to allow to exchange large quantities of data. In this case the factory network is based on a Fipway architecture. Cell level: each device or group of devices are controlled by an overall control system (PLC). Machine or field level: each device includes a group of intelligent sensors, actuators and simple control systems that communicate at this level. Fieldbuses (FIPIO) are used. - ESN system advantages: Main EDIBON SCADA NET SYSTEM innovations: Industrial Ethernet information functionality. Central PLC (PLC NET interface) is used to coordinate large amounts of I/O or data transfers between PLCs. Ethernet network provides extremely fast data collection and control of the plant floor network. This design is very advantageous for anyone who needs real-time access to plant diagnostics (either locally or remote-controlled). Global availability of information. Optimised traffic load allows users to make tuning changes to achieve an optimal performance. Manufacturing data can be easily visualised. Synchronisation of distributed applications. Automation infrastructure is more flexible and adaptable. Any kind of PC and other electronic components can now be integrated into your automation infrastructure. Your plant will remain infinitely expansible and upgradable. - Main possibilities of the system: 30 students simultaneously work with 30 different units. Any student can work simultaneously doing Real Time Control. The teacher can see in his computer what any student is doing in any computer at any time. This system can be linked with any other ESN System (EDIBON Scada Net System). The ESN System is modular, open and expansible. Each unit of the system is open and expansible. Any unit and any system can be visualised simultaneously in n screens by using repro-projection multimedia system. The system is supplied with all necessary accessories, computers etc. COMPLETE SYSTEM FOR FULL RUNNING. Each unit is supplied with 8 manuals. The system has its own manual.
