Integrated Architecture Helps Bel Group Save Costs

Challenge

This American adventure is a new industrial and technological challenge for Bel and its corporate engineering team. A steering committee was created especially for the project. This committee included the Bel engineering members, Rockwell Automation technical experts and sale representatives from France, Europe and US South Dakota.

For several key suppliers in the fields of process, mechanization and packaging, a support program was established by Rockwell Automation. Eight French and European OEMs received training to assist them with their development efforts while also complying with the hardware and software standards defined by Bel. The steering committee also assisted with the process of gaining the certifications required in America, such as the UL electrical regulation and the 3A and PMO Food standards.

Solution

During the meetings of the steering committee the technical decisions were made. For the software, the key word was standardisation. “As we wanted our applications to be easy to maintain and connect easily with third-party software, we selected two programming standards: PackML 3.0 for the conditioning, and ISA 88 for the process,” comments Bagourd. Even if ISA 88 is a standard, its deployment has to be specific for each company. This meant that the Bel teams had to develop their own standard if they wanted to be able to easily integrate pieces of software that are developed by suppliers.

“We described the main graphical objects we wanted for the applications, so that the symbol used to describe, for example a motor, would be the same in the whole factory. We also defined some basic functions, such as the acknowledgement of an alarm or the way a machine can be switched to manual mode, explains Christian Villedieu de Torcy, head of automation and industrial computing projects in the Bel Group engineering department.

All these graphical objects and basic functions were sent to the suppliers, so that they could implement them in every machine or program developed for the Brookings factory. “And we were there to coach the suppliers whenever they needed help in using the standards or working on our products,” adds Dominique Leroi, sales engineer in charge of consumer packaged goods activities at Rockwell Automation, France. At the request of Bel, a post installation audit was conducted by Rockwell Automation in order to check the correct implementation of the automation standards selected by the steering committee.

Standardisation efforts were defined for the hardware element of the project, too. A large part of the Integrated Architecture portfolio from Rockwell Automation was deployed, starting with an EtherNet/IP network – chosen by Bel for the backbone – and a device level ring (DLR) network for the copper network that links the 40 automation controllers to the equipment.

Allen-Bradley® Kinetix® drives are connected directly onto the EtherNet/IP network, which manages the multiple axes deployed in the cheese-pressing machines. With regards to safety, the French company selected Allen-Bradley GuardLogix® safety controllers. “Each sector of the production line is controlled by a safety controller and all of them are linked through an EtherNet/IP network; this allows Bel to stop a sector while the other areas are still running, which greatly helps to improve productivity,” adds Leroi.

The utilities management system (water, cooling and compressed air networks) is connected to FactoryTalk® View supervision software, via a dedicated controller. “It is the first Bel factory in which we integrate the energy management into the supervision system,” notes Christian Villedieu de Torcy. And thanks to the Allen-Bradley PowerMonitor™ counters installed on the electrical cabinets, Bel automation engineers are able to develop any kind of algorithm they wish to use to reduce their energy consumption.

Production data are also tracked and traced with FactoryTalk Historian Software for quality audits.

Results

By deploying different technologies that help the company leverage the Connected Enterprise, production at the latest Bel factory has started and ramped up without any problem. “We are even ahead of the plan we had established at the beginning of the project,” emphasizes Bagourd. “The unit is already running 24 hours a day, 7 days a week and our objective to reach a capacity of 10,000 tons per year is very close.” The standardisation efforts defined by the steering committee have also been very useful. “The programming standards makes the cheese plant’s maintenance easier” says Christian Villedieu de Torcy. “If a sensor needs to be adjusted, or if a production cell is stopped, our technicians can quickly find the information they need in the programs and the productivity is increased.” And among the evolutions expected for 2015, Bel Group is thinking of using FactoryTalk AssetCenter to manage all the software activities in the factory. Every access, update or modification will be recorded.

Finally, from a hardware perspective, the Bel suppliers have built their solutions with a list of equipment established with Rockwell Automation, significantly reducing the spare parts inventory. Bel has even gone further by signing, for the first time, a Part Management Agreement (PMA) with Rockwell Automation. “With this agreement, we have a consignment of stock of spare parts, which is the property of Rockwell Automation, but is located in the Brookings factory,” explains Christian Villedieu de Torcy. “We can access the parts we need whenever we need them, which saves us costs and, more importantly, we don’t have to handle the obsolescence of parts in our warehouse anymore.”

The results mentioned above are specific to this customer's use of Rockwell Automation products and services in conjunction with other products. Specific results may vary for other customers.
