Modulus

When the Modulo Division (MOD) function receives power flow, it divides
input IN1 by input IN2 and outputs the remainder of the division to Q.
All three operands must be of the same data type. The sign of the result is always the same as the
sign of input parameter IN1. Output Q is calculated using the formula:
Q = IN1-((IN1 DIV IN2) × IN2)
where DIV produces an integer number.
The power flow output is always ON when the function receives power flow, unless there is an
attempt to divide by zero. In that case, the power flow output is set to OFF.

Parameter Description
IN1 Dividend: the value to be divided to obtain the remainder;
shown to the left of MOD in the equation IN1 MOD IN2=Q.
IN2 Divisor: the value to divide into IN1; shown to the right of MOD
in the equation IN1 MOD IN2=Q.
Q The remainder of IN1/IN2.
