Function Code 7 – Square Root
GENERAL DESCRIPTION
This function computes the square root of the input signal in engineering units. The
output equals a factor (k) times the square root of the input. The equation for this
function is:
S1 = Input value.
S2 = Gain value (k) in engineering units.
Y = Output value (Y = 0 if S1 <= 0).
Y = S2

UTILIZATION
The MOD 30ML/MODCELL compound FC3 used here has an EX function block
(Expression block).
Figure 7 .1.
Function Code 7
The Expression block FC7 has an input called S1. The input for which Square root is
required is connected to this. The result of the EX block FC7 is the final result.
In the EX block FC7, enter the constant S2 in floating point units. The final result is the
square root of S1 scaled by S1.
