Bitmeldungen im TIA Portal im HMI projektieren

In this video, Michael Grollmus shows you how to configure bit messages in the HMI within the TIA Portal. The initial situation: In the plant model, there are two variables that provide information about the fill level of a pallet. The observed value of one variable changes to "TRUE" as soon as the pallet is almost full. The observed value of the second variable changes to "TRUE" as soon as the pallet is full. The goal is to display a bit message on the HMI as soon as a TRUE message appears for each of the variables. In the first step, a word variable is created that combines both bit variables. This is loaded into the PLC controller. In the next step, a message class is created in the HMI. To display the bit messages in the HMI, a new screen is added. The message display is inserted into this screen via drag and drop from the controls, and the message classes to be displayed are defined. In addition to the message display, a new message should also be displayed on the global screen of the HMI.
