Okay i am trying to answer your questions. 1. Yes the Picture should be created when there is a bool item that changes from 0 to 1 2. The Image should be downloaded on the Client Browser, because the Server is running on the ctrlX PLC but i need the files on the PC where the HMI is displayed. 3. The HMI is only viewed by one System at the Time and the Trend Object is always on the screen but it is not always in Live Mode 4. I know that there will be a download dialog but unfortunately this is the only solution that i know to get this to work. 5. You are right an OPC UA Item is used but the image saving can be expected through the process of the machine and the user will be given an information that an image of the Trend Display will be created 6. This Case can not happen since it is required to always show the HMI when the machine is running by regularities 7. I dont need that functionalities Another Question would be if I could directly write to the file system of the Computer, if the Server is running on the PC instead of the PLC so that i dont need to download the files from the Browser?
