gfos.MES | Production data acquisition The production data acquisition (PDA) provides the user with a starting package that can easily be configured and expanded to meet your requirements. This is because the PDA system can be expanded by further modules, linking together in an intelligent manner all the influential factors for an optimized manufacturing process. gfos.MES thus fulfills not only VDI (Association of German Engineers) directive 5600, but the system is also compelling thanks to its flexibility and intuitive user guidance.
