Supervision of the vats: The house of champagne Veuve Clicquot chooses PcVue d'Arc Informatique
Friday, February 28, 2014Description :
Veuve Clicquot produces a champagne of first quality and world renown. To control the fermentation of its 400 tanks, it has opted for the PcVue supervision system of ARC Informatique. Already well instrumented and automated, now well supervised, the house of champagne now has a smart vat room.
Veuve Clicquot is a world-renowned champagne house. Established in 1772, this prestigious house is a subsidiary of LVMH. His fame is evidently not accidental. The house does not compromise with quality. His motto is "one quality, the very first." To ensure that the best quality wine is always available, it must, among other things, perfectly supervise its production systems.

Thus, at the end of 2012, Veuve Clicquot renovated the supervision system of its winery, where the wine is vinified after the grape harvest and the pressing of the grapes. The monitoring of vats in which alcoholic and malolactic fermentation takes place is crucial. It was therefore very important for the house of champagne to replace its supervision system which had ten years of age by a newer and more efficient solution. The software in place was at the end of its life. Its editor no longer ensured its development. "It was necessary to replace it with a long-lasting solution that the editor ensures the follow-up for many years," says Franck Berruyer, commercial engineer at Arc Informatique publisher of the PcVue supervision system that was commissioned at Veuve Clicquot. "In addition to various technical aspects, we opted for the PcVue 10 software suite because of the trust relations we maintain with Arc Informatique and also because the price of licenses is economically adapted to the need of Veuve Clicquot," reports Stéphane Fournier, SF2I, the company that was responsible for the development and integration of the supervision application. PcVue also had the advantage of having the same HMI as the old solution. This was important not to disturb the habits of the operators who have access to it. According to Guy Jendryka, head of the Electricity, Automation and Industrial Informatics department at Veuve Clicquot, one of the highlights of PcVue is its accessibility in terms of tuning and programming: "With our previous system, you really had to be a To be able to evolve the application. With PcVue, it's easier to make changes according to our needs. "

PcVue's object-based development architecture has also greatly facilitated the design of the monitoring application. Since the winery was equipped with 400 cuvettes of different types and volumes (50 hl to 725hl), developers had to be able to rely on models to reduce programming times and maintenance. Depending on the type of tanks, they are equipped with one to three temperature sensors for their thermal regulation and manual or automatic valves. The application manages about forty variables per tank, some 16,000 in total! "The object development architecture delivers time savings and simplifies operations. Once the model is realized for the ten models of existing tanks, it is enough to instantiate the objects and automatically generate the variables of communication ", explains Stéphane Fournier.

Thanks to the virtualized architecture of PcVue, the supervision application runs on a server installed in a secure, air-conditioned, and healthy room. It is thus protected from ambient humidity. The maintenanceability is simplified as well as the portability of the application on new physical machines. The reinstallation and commissioning times in the event of a failure are considerably reduced since in such a virtualized environment the software application is decorelled from the hardware part.

Five web clients allow supervisors to access supervision via their PC for viewing and choosing instructions. But operators can just as easily control and control the application from the 42 "touchscreen installed in the lobby. The operation of the installation is visible to all visitors. The application communicates with the controllers via the Modbus TCP / IP protocol, but a virtual private network (VPN) link has been set up to collect information from the remote vats. All the tanks are not located in the same place: 14 fermenting modules are in Reims and 4 others in different communes distributed in the vineyard distant from 30 to 200 km! The VPN provides an obvious time saving. "The supervision of all vat rooms from one point avoids the need to travel by car. Alerts for serious control problems are indicated by supervision, "says Stéphane Fournier.

Thus, Guy Jendryka can now monitor all his tanks from the PC of his office: "thanks to the supervisor PcVue we have a smart vat room. We can see from a given point everything that happens from the point of view of thermoregulation ".

Thanks to this positive experience, Veuve Clicquot's technical teams quickly realized the potential that PcVue could offer in other fields. Thus, the supervision system is not limited to monitoring the fermentation of wine in the vats. It has been deployed for the control of the production of cold during the step known as the passage to the cold after the assembly phase.

Here the PcVue application does not control operations. It is used only for the visualization of the parameters with the possibility of archiving, history and plotting temperatures, defects etc. It is also used for the monitoring of effluent discharge from the two treatment stations: management of Acid and soda levels, traceability of pH and flow values ??(weekly dashboard for the Dreal) and to ensure the replenishment of the products following the alarms levels by sending mail to the managers. And it's not over ! PcVue continues its expansion: by the end of the year it will be operational on the line of dressing (laying of the cap and labels on the bottles before shipping). "It will be used in particular to retrieve production orders from SAP and make available the laser identification codes to be affixed to the glass and the back label," says Guy Jendryka.
