Hi all,

Simple question.

I want trending functionality as in the old e-terminals. So I want to trend values over an extended time, even if the screen reboots or gets updated. And show the last, say hour in the trend viewer.

How can this be achieved?

Hi Ton!

Use the dataloggers for saving data and in the trend you point towards the datalogger as source.
