Hello,

I would ask You for information about reading data from SD card on PLC HMI.

Program is done, costumer demand is to have possibility to record  and read a trend (with temperature and pressure data) from every machine cycle.   My  V700 does it well, and costumer  read data from SD on one of HMI screens.

Problem is with preview of trends, because first what i see is oldest recordings and ofc (depend of number of recorded cycles), we need a lot of time to find newest trends.

Is there any system solution for previewing, first from the newest trends (last recorded trend) to oldest?

Thank you in advance,
