SQRT Function Block 

Description 

The 

SQRT

 label stands for 

Square Root

.  

 

 

 

This block is part of the 

Calculations

 category. 

Function 

Extracts the square root of the analog input (X) as long as the input is greater than the configured 
DROPOFF value. 

•

 

If X > DROPOFF, then: OUT = square root of X. 

•

 

Otherwise, OUT = 0. 

Input 

X

 = Analog value for square root extraction 

Output 

OUT

 = Square Root value 

Block properties 

 

 

 

Double click on the function block to access the function block properties dialog box.
