An Application Story

CROSSLINK è stata invitata da Advantech (fornitore di elettroniche) alla più importante manifestazione europea di automazione: BIAS – Convegno Mostra Internazionale dell'Automazione, Strumentazione e Microelettronica, dove Paul Pfletschinger ha tenuto una conferenza sul primo sistema di gestione di un tunnel di verniciatura gestito da PC. Il sistema gestiva anche flussi e pressioni dell'aria all'interno del tunnel di verniciatura, l'usura dei filtri, i forni, le temperature dei lavaggi e i tempi di lavorazione.

Lo stesso sistema, integralmente sviluppato e realizzato da CROSSLINK, è stato pubblicato negli USA e diffuso a livello mondiale come esempio significativo e tecnologicamente innovativo nel campo dell'automazione PC-based.

Il software dedicato è stato sviluppato integralmente da Paul Pfletschinger.

L'importanza dell'applicazione è sottolineata dal fatto che ha permesso di rispettare gli standard qualitativi in ambito UNI-EN-ISO 9002, finitura e verniciatura automotive. (Fiat Lancia Alfa Iveco Peugeot Mercedes Daimler Chrysler)


Painting Tunnel Automation

Location : Italy


 An Italian manufacturer uses the ADAM-4000 series to automate a painting tunnel, and thus optimizes the painting process and increases product quality.

Introduction
Following the setting up of a new painting tunnel, the manufacturer needed to optimize the process of painting, as well as reduce post-processing of the painted items. Post-processing was often required to eliminate surface defects, which decrease product quality.

System Requirements
Product quality was determined by the continuous control of pressure inside the tunnel andby the cleaning of the filter cells. In order to obtain higher quality at lower costs, the manufacturer required the following:
1. Non-stop real-time control of internal pressure values and filter status
2. Data logging and a database for historical plant variables
3. Rugged and reliable hardware that can cope with harsh environmental conditions

System Description
The system consisted of two PC units linked together by an Ethernet LAN. One of which was remotely located and was used for monitoring and data logging. The other PC was located inside the control room and was responsible for real-time control of the tunnel. The inflow and outflow of air was controlled by the Advantech PCL-727 12-channelD/A output card, while pressure sensors, temperature sensors and On/Off switches were handled respectively by Advantech¡¦s ADAM-4016, ADAM-4013, and ADAM-4060 modules. An RS-484 network linked all modules to remote PC stations. The entire application software had been developed using Advantech's high speed DLLs in a Visual Basic 5.0 environment.

Conclusion
Advantech's total solution offered the customers a system with an open architecture, which easily integrated different parts. Furthermore, Advantech's plug-in cards and field bus devices ideally met the customer's needs.
