Hi,Mikhail
Thank you for your help all the time.
Sorry, I failed to describe my needs clearly before. I want to write the data (data1, data2, data3…) obtained by Modbus into the SQL table at a frequency of once a minute. The columns of the SQL table are arranged in accordance with the (writing time, data1, data2, data3… ).Retrieving data from Modbus has been successful. But I don’t know how to write SQL in the above arrangement.
