Presentata a Plast 2012 la soluzione di controllo da remoto per tablet e smart phone

Lider Makina, uno dei principali produttori turchi di linee e impianti di estrusione per la produzione di tubi e profili di plastica, ha presentato in occasione del Plast 2012 una soluzione estremamente innovativa per l’estrusione di tubi di plastica e profili.
Lider Makina produce una vasta gamma di estrusori bivite, estrusori monovite,banchi,traini e accessori per linee di estrusione di tubi e profili. Più del 70% degli estrusori viene esportato in oltre 30 Paesi.
La qualità e la tecnologia degli estrusori Lider Makina è garantita dagli elementi di sono composti. Grazie ad una attenta ricerca di fornitori di qualità, in grado di offrire soluzioni all’avanguardia in termini di strumenti e dispositivi elettronici, Lider Makina offre soluzioni competitive e tecnologicamente all’avanguardia.
In particolare, la soluzione presentata a Plast 2012 si distingue per la possibilità da parte dell’End User di controllare e monitorare la macchina da remoto, in modo facile e immediato, attraverso strumenti quali tablets e smart phone.
La connessione remota è realizzata attraverso un client VNC per piattaforme Windows, Linux e Tablet, che consente il controllo remoto della macchina senza aggravi di costo . Ciò significa che non è necessario sviluppare alcun codice aggiuntivo per ottenere questa funzione che consente di impostare/verificare il funzionamento della macchina stando in qualunque posto del mondo dove sia disponibile una connessione Ethernet.
Il controllo dell’estrusore è affidato ai PLC della serie Gilogik II e agli HMI GF_Vedo di Gefran. Gefran, azienda italiana leader nella progettazione e produzione di dispositivi elettronici per l’automazione, offre piattaforme di automazione con possibilità di connessione Ethernet, grazie alla quale è possibile mettere in comunicazione macchina e operatore da remoto. Lo sviluppo dell’applicazione per monitoraggio dell’impianto da remoto, inoltre, è di competenza degli uffici tecnici di Lider Makina.
Grazie all’utilizzo del PLC Gefran per il controllo, l’utente ha la possibilità memorizzazione dei dati della macchina con flash card, registrare gli allarmi, memorizzare e caricare le formule e parametri di processo.
Lider Makina si propone al mercato europeo e mondiale come partner tecnologico, in grado di fornire soluzioni su misura ai propri clienti, sviluppate in funzione delle loro richieste ed esigenze.

Desigo V5: Innovations from Siemens increase building efficiency
The Siemens Building Technologies Division has introduced version 5 of its Desigo building automation system. Its innovative products such as Total Room Automation as well as efficiency features, like RoomOptiControl and Eco Monitoring, give building operators and users an active role in energy management, leading to permanent reductions in energy and maintenance costs.
A state-of-the-art building automation system is always optimized for energy-efficient operation. However, these optimized settings may start to drift over time. One of the underlying causes is often a lack of transparency for users who simply don't know how the setpoint changes they make can impact energy consumption. This is particularly true for air-conditioned rooms which are also equipped with lighting and sun protection controls. The new version of Desigo keeps room users and building operators apprised of the building's efficiency status. Feedback to users is given using the innovative Green Leaf display, adapted to the expertise and control options of each user group. The system makes it possible to change settings if needed to restore optimal energy efficiency. A study by Technische Universität München (TUM) indicates that by actively involving operators and users in the energy management of a building, energy consumption can be reduced by up to 25% without affecting comfort.
Total Room Automation offers energy savings without reducing comfort
The open, programmable room automation range Desigo Total Room Automation (TRA) is a holistic solution encompassing the HVAC, lighting and shading disciplines. Desigo TRA uses an innovative efficience feature called RoomOptiControl. It automatically detects unnecessary energy consumption in the room and notifies users by changing the color of the Green Leaf icon on the QMX3 room control unit: If room operations are energy efficient, this icon is green. If settings made by a room user lead to unnecessary energy consumption, the icon turns red. To reset room control to energy efficient operation, the user simply presses the display and the Green Leaf icon returns to green.
Using BACnet/IP, PXC3 room automation stations—also part of the TRA package—are integrated seamlessly into the PX automation level with its primary systems (heating generators, HVAC main units and cooling generators). The primary systems are controlled directly through the demand signals from the rooms. This means that the primary systems are only turned on if needed and their operation is adjusted so it meets the room requirements without exceeding them. One room automation station can cover multiple rooms. TRA offers complete integration of KNX, DALI and EnOcean devices; existing or new sensors and actuators from Siemens can be incorporated as well.
Eco Monitoring to reduce energy consumption and wear
Eco Monitoring is another innovative efficiency feature of Desigo. It monitors ongoing operations of HVAC systems based on energy-related quality condition indicators such as readings from temperature, humidity and pressure sensors, runtime, switching behavior and operational performance of the systems. Should deviations from the target state, inefficient operations or increased energy consumption occur, the building operator is notified via the Green Leaf display on the Desigo Insight management station. Current and future international standards (such as EN 15323:2007) require such a feature in order to optimize building operations over the long term.
Desigo Eco Monitoring not only helps optimize energy consumption, it also reduces wear. Thanks to its dynamic behavior and timely reporting, the Eco Monitoring feature recognizes unfavorable system operations early on, allowing operators to intervene immediately before any negative impact occurs. If desired, operators can choose to be notified of unusual events via text messaging (SMS), fax or e-mail.
Expanded networking of the automation level
Starting with version 5, Desigo also offers expanded end-to-end networking of the automation level. Enhanced support for communications standards ensures efficient system integration. The PXC series of compact automation stations has a higher number of universal inputs/outputs, which makes them much more flexible. To protect existing investments, different device generations, such as PTM and TX I/O modules and RXC room controllers, can be used in parallel on the same PX automation station.
