Plugfest is a popular opportunity for members to test their FDI Devices and FDI Hosts together in an organised but informal environment as part of the FDI Working Group activities during the FCG meetings. Twelve member companies tested 15 Devices (Pressure, Temperature, Flow, Level, Analytical and Positioner) on 5 different automation hosts, plus the FDI Reference Runtime Environment. Profibus, HART, FF and Modbus protocols were covered. PNO was represented at the Working Group meetings by Peter Wenzel and Alexander Kaiser. This was the 3rd FDI Plugfest, stay tuned for information about the next ones.
