wincc flexible trend view of array value's

[frank_1988]

At the moment I’m working on a project to log a PID input (weight sensor) within a sample period of 20ms.

Because Wincc cannot read value's every 20ms,(maximum for the pc is 100ms and max of a screen is 1s) I did make a FB witch put very 20ms a INT value into an 600 INT long array.

In the tags of Wincc flexible I read the db as an array.
I did put 200 small ellipse on my screen and connect them to array[0] -> array[199] when I test the program it is working fine, but the max of tag's on a screen is 400.

Is there a way to edit corner points of an polyline with scripts?
Or can I load the array into a trend view?
Or can I load the array into a data log and then into a trend view?

I hope you can help me,

Look into bit-triggered buffered trends.

JesperMP,

Thank you for your very quick replay!

But I don't know how to fill in the 'buffer bit triggered' trend.
Trend buffer: array
Switch buffer: activate?
Bit: 16? because I read a INT
Trend request: array?
Trend transfer1: I cannot select a INT form the array, or the array

I have a array with 600 INT value's witch all the information.
