Process automation for the paper industry

Despite automation, OnControl focuses on the papermaker who manages and coordinates technical processes. OnControl interfaces provide user-friendly visualization of the most important information, tailored specifically to the paper industry. Thus, OnControl supports the papermaker in starting different machine sections and maintaining their operating stability.

In addition to machine- and process control, OnControl also integrates our Quality Control System and with OnC.DriveCommand our solution for the coordinated drive controller into one system. The advantage for the user: Where previously two visualization systems with two alarm systems had to be observed and two alarm systems correlated. Now, OnControl carries out all of these functions. This simplifies visualization, troubleshooting, and maintenance for operators and maintenance personnel – right down to the drives.

All safety function are integrated in OnControl according to current standards – without additional hardware. A detailed risk assessment carried out for each project is the basis for the definition of measures to meet highest HSE-standards.

Integrative, object-oriented CAE systems are used for basic and detailed engineering – e.g. hydraulics, pneumatics, and circuit diagrams. At Voith, programming is the exclusive responsibility of engineers who know every last detail of all stock preparation processes. If errors arise, maintenance personnel can remedy them quickly because they have direct access to all documentation via OnControl operating stations.

To minimize troubleshooting and the corresponding downtime, all relevant information is available at the OnControl operating stations. With first-value identification, OnControl displays the original cause of any error message. This guides the operator through the process control system to the origin of the problem, which can often be solved directly. Such analysis is possible even for operators who have no knowledge of the control system technology.

Experience shows that the greatest loss of time in commissioning of new paper machines is due to excess interfaces between different suppliers of operation, drive, control, and measurement technology. We are a full-line-supplier, who offers all technologies. Thus, there is only one contact person for all components in the scope of supply: the Voith project manager. When this service is used, we bear sole responsibility for all performance features of the overall package. This ensures the success of the entire project.
