Mathematic instruction
Short description
The mathematic instruction block calculates the value AQ of an equation formed from the
user-defined operands and operators.
Connection
Description
Input En
A positive edge at input En enables the mathematic instruction function block

Output AQ
The output AQ is the result of the equation formed from the operand values and
operators. AQ will be set to 32767 if a divide by 0 or overflow occurs, and -32768
if a negative overflow (underflow) occurs.
