Hello,
I would like store some value and than display on HMI like a trend. The idea is:
Do the process and during this process record value of pressure and storage on the memory card. After the process is finish we stop record value. After each process I would like to creat loggs and later i would like to have chance to access for each trend from last 7 days for example. How can i do this? from PLC logging or use HMI historical data logging?
