Can umati lead us out of the "interface jungle"? Under the umati (universal machine technology interface) brand, a working group of the glass technology forum of the VDMA is advancing the development, dissemination, and use of open, inter-company machine interface standards. GLASWELT asked Dr. Klaus Mühlhans of A+W Software exactly what this involves and what the significance of umati is for the OPC UA standard and its dispersion. Dr. Mühlhans leads the VDMA working group together with Dr. Markus Schoisswohl (Hegla). GLASWELT – Why is the umati standard so important for the flat glass industry? What are the specific benefits for processors and insulated glass manufacturers?
