Rockwell Automation’s PlantPAx process control system is providing system integrator Enfasi with an integrated automation solution for paper manufacturing
F
or the pulp and paper sector (which is still an industry with a strong
footprint in the Lucca area, in Tuscany, Italy where Enfasi is based), the company delivers complete automation systems and offers its own Quality Control System (QCS), a solution designed to fit the increasing demand of quality in the paper manufacturing sector. “A couple of years ago we decided to propose a QCS, which is entirely designed and developed by us,” said Marco Nieri, Enfasi co-founder together with Paolo Morselli, Antonello Lisi and Gabriele Campesan. “In 2012 we focused on the QCS development, exploring the very specific sector of quality control systems, which represented something different from our traditional Distributed Control Systems (DCS) field.” Enfasi’s customers in the pulp and paper industry are both machine builders and paper manufacturers. As Nieri added, “In those cases where our customer is the paper manufacturer and the end user of the control system, we can say it’s easier to understand each other as we speak the same language.”
KEEPING THE END USER IN MIND To provide end users with a user friendly interface, which allows them to monitor and manage the paper manufacturing process and the paper quality specifications, Enfasi decided to base its automation solution on the Rockwell Automation process control system. “We selected Rockwell Automation
because we wanted to go to the pulp and paper market offering a state of the art automation system, which could give added value to the customer and could

represent a differentiating key factor for us,” said Morselli. The Rockwell Automation PlantPAx system allows Enfasi to offer an integrated solution, on a single platform, which manages both the production line and the quality control system. “According to this approach, our customer is provided with an efficient single tool to manage its plant and to fit the increasing demand of quality for the final product,” said Morselli.
A SINGLE PLATFORM The QCS has been designed to inline measure and control the paper quality specifications (weight, moisture, ashes, etc). Enfasi decided to build the hardware and software architecture of its system using only Rockwell Automation components. Enfasi’s aim was to create a single control, visualisation, development and diagnostics platform, which had to include the QCS, the DCS and the drives. In the solution, three programmable automation controllers (PAC) manage the QCS, the DCS and the Allen Bradley drives - the process measurement devices, the control system and the visualisation platform communicate via Ethernet. The operator can monitor the plant using the FactoryTalk View software. PlantPAx, the Rockwell Automation process control system, manages the signals coming from the measurement devices in the plant and the data coming from the paper making industrial process. Based on the Rockwell Automation Integrated Architecture, PlantPAx, with its standard database, makes the data generated in the system immediately available and accessible for the different

software modules in the overall system. The single interface and the common
software environment are the peculiarities of the Enfasi automation solution - all the systems in the plant use the same instructions, are connected on the same network and share the same development and visualisation platform. According to this system architecture, the paper manufacturer can rely on a single platform to have access and to supervise the entire plant, and can include all the devices it needs on it.
SUMMARY Using a common programming environment and the high data processing capacity of the PACs, Enfasi can save time in system engineering and can focus on the interface customisation. Enfasi adapted the PlantPAx library to the requirements of plant floor operators in the pulp and paper industry, which usually need a small amount of information and are not interested in having the big quantities of data required in more complex process industries. The Factory Talk View Studio software
also helped Enfasi to implement advanced graphic controls for production trends analysis, which can be organised according to pulp and paper industry specifications. Morselli concluded, “Thanks to Rockwell Automation and to the technical support provided by the Rockwell Automation guys, we hit our target and can approach the pulp and paper industry as a system integrator with a unique offer.”
