4.10.5 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.
Mnemonics:
MOD_DINT
MOD_INT
MOD_UINT
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.
