Unistream Trend & Data Sampling


Emrah AKAY

Recommended Posts

Hi Support, I am Emrah at TESAN from Istanbul,
I wrote a program with UniStream and insert a memory card. But there is a problem; PLC is saving random data sampling.

for example I saw the trend history, it keep in memory different time or didn't keep in memory sometimes. before it saved three hours and later didn't save two days.
an other time when I saw it saved five hours but didn't save three days. I used trend start bit with 'General ON'. But it can't keep in memory every time.

What is your solution?

Thanks for your help.
