Using the example project with HY.City.Bremerhaven from the hydrogen industry, we demonstrate in the video how to safely monitor dynamic process values when filling and emptying hydrogen trailers. We show step by step how to set up the user program with the PNOZmulti Configurator software tool. You will learn how to create the hardware configuration in the software tool PNOZmulti Configurator with the safe small controller PNOZmulti 2 with the base unit PNOZ m B1, the analogue input module PNOZ m EF 4AI and the input/output module PNOZ m EF 8DI4DO. We also explain the software configuration and other important topics.
