Hello Denilson, As a follow-up of you post, I have a use case which needs your further assistance. We have a S7 1212 which controls a water treatment demo in our lab, we collect process variables and plan to send them to Mindsphere for data analytics applications. We woud like to buuild this demo to show Mindsphere to customers. At this moment, we want to - 1. Collect process variables and save to memory card; 2. Build up TCP/IP to TCP server (in our lab now) once a day; 3. PLC reads log data and send the historian data of the entire day to the TCP server. 4. PLC deletes the log data which has been sent to the TCP server I saw that your sample is very helpful for the first step. However, I am not sure how to read log data from memory card and how to delete it from memory card by running PLC application program. Your assistance is highly appreciated.
