Description of the function
The mathematic instruction function combines the four operands and three operators to form
an equation. The operator can be any one of the four standard operators: +, -, *, or /. For
each operator, you must set a unique priority of High ("H"), Medium ("M"), or Low ("L"). The
high operation will be performed first, followed by the medium operation, and then by the low
operation. You must have exactly one operation of each priority. The operand values can
reference another previously-defined function to provide the value. The mathematic
instruction function rounds the result to the nearest integer value.
The number of operand values is fixed at four and the number of operators is fixed at 3. If
The number of operand values is fixed at four and the number of operators is fixed at 3. If
you need to use fewer operands, use constructions such as " + 0" or " * 1" to fill the
remaining parameters.
You can also configure the behavior of the function when the Enable parameter "En"=0. The
You can also configure the behavior of the function when the Enable parameter "En"=0. The
function block can either retain its last value or be set to 0.
