In automation sensor and application data from machines are transmitted from the field level to a central control unit. Moving parts, e.g. in sewage treatment plants or cranes, require wireless communication solutions for the different protocols (fieldbus). Therefore, radio links are used. The modules of the DATAEAGLE 3000 series “speak and understand” PROFIBUS with or without support from PROFIsafe. The patented data pre-processing including filter function ensures a particularly high level of system stability and availability.
