The Demig prosys/2 process control system

Simple operation with plug and play

prosys/2 is the heart of our process control system. Specially designed in 1987 for the unique requirements of heat treatment, we have consistently adapted and developed our proven software solution to meet changing technical requirements, and to work with new operating systems and modified user interfaces.

In addition, you can access prosys/2 on any device within the IT security architecture of your company.

What problems can prosys/2 solve?

Our process control system offers users support in operating their heat treatment systems. In addition, Demig process controllers can be easily connected and exchanged via auto configuration. Prosys/2 offers all options for data backup and back-ups of relevant process data recording in in-process controlling. System manufacturers benefit by saving time, since prosys/2 is a plug-and-play solution that is quick and easy to integrate.

Are you looking for intuitive software to automate in-process controlling? Then our prosys/2 auxiliary module “prover/2 automation” is the right choice for you.

In-process controlling with prosys/2

Our process control system combines all control systems on the process level, facilitating seamless in-process controlling for you. You can access a complete overview of all ongoing processes, as well as detailed views of all systems. You can start and monitor processes via the operating interface, and control them if necessary.

The software's scope of functions also includes complete process documentation in accordance with CQI-9, redundant measured value recording and a reliable backup/restore scenario.

Customised automation to meet your individual needs.

prosys/2 can communicate with all commonly available ERP systems. Standardised interfaces allow for seamless integration into your company software environment.

Thanks to the open, expandable structure, the process control system grows to meet your needs and requirements, up to full automation of your production line with our prover/2 software.

In addition, our technicians and engineers can develop custom implementation options with you, perfectly tailored to your processes. Since we design and develop our systems in-house, we can react freely and flexibly to new requirements and implement new options at any time.

Easy integration and flexible expansion

One key advantage of prosys/2 is its multi-dimensional scalability. It can be used vertically with one client and control system, as well as horizontally with multiple clients and control systems. If you integrate additional Demig process controllers later on, the respective configuration is transferred automatically, along with visualisation and language files.

Of course, prosys/2 also works with non-Demig control systems. This makes it simple for you to integrate and expand your existing system infrastructure. You enjoy maximum functionality thanks to the combination of Demig controllers and our control system.

Do you want to update your existing control systems? Thanks to excellent compatibility with previous models, prosys/2 can be seamlessly integrated into your existing environment.

We would be happy to inform you about our innovative process control system in more detail during a personal consultation. Just contact us via phone or email.
