Limit Scaling trick
To get a direct precise reading from an analog input with 2 digits behind the decimal fraction
A little trick.
A sensor from -20 °C. to +70 °C.
I needed at least 1 digit behind the decimal fraction
So this is what I came up with.
I increased the sensor values in the LS by 10 or by 100 and looked at the actual output.
See example : Scaling_Trick.zip
In the Easy Soft simulation the value (0-1023) goes up by 10 points at the time, BUT :
In REAL TIME the digital (0-1023) values go up a point at the time so it's very accurate.
The tag conversion in Winlog Lite with a division by 100, and the template output with accuracy of 00.00
Works as a charm.
Just a little tip.
