A range of automation concepts for gas control is available for thermal-processing facilities and industrial plants producing steel and castings. Possibilities range from data exchange to “conventional” analogue standardized interfaces and digital networking using all common fieldbus protocols all the way to plug-and-play MFC assemblies, as well as complete control cabinets including all components for gas control. For smaller or simpler plants where only small amounts of data need to be transferred, the conventional analogue interface is ideal. Start-up and maintenance are straightforward, and signals can be checked with the help of simple aids. If diagnostic data and device state are to be transmitted in addition to setpoint and actual values, the mass flow controllers can communicate via digital interfaces.
