Hello,

I m working on a process control project. I have controlled the system according to temparature, pressure, and weight(by measuring with loadcells). I have used S7-1200 PLC and TIA portal V13 for the programming, and KP1200 for the monitoring. But now I need to call the sensor value or any tag value according to the time. I want to type the time on HMI and see the values of the sensors or tags data at this time. Is it possible?

hi yeliz,

you need to save the data in a DB, or better in a datalog-file. 

Maybe the following Application-sample can help you:

Process Data Acquisition and Monitoring with SIMATIC S7-1200 (Data Logging)

hope this helps,

Thanks mopS04 for your suggestion.

 But in this link they use internet and computer to log data. I want it to see the data on HMI screen. I just want a field where i can type time and to see what was the the data at this time.
