	The function MAX3 delivers the maximum value of 3 inputs. Basically, the in standard IEC61131-3 contained function MAX should be equipped with a variable number of inputs. However, since in some systems the MAX function is supported only two inputs, the function MAX3 is offered.

Example:

MAX3(1,3,2) = 3.
