*   Multiply

Operator - Performs a multiplication of all inputs.

Inputs

IN1 : ANY_NUM  First input
IN2 : ANY_NUM  Second input

Outputs

Q : ANY_NUM    Result: IN1 * IN2

Remarks

All inputs and the output must have the same type. In FBDClosed "Function block diagram" A function block diagram describes a function between input variables and output variables. A function is described as a set of elementary blocks language, the block can have up to 16 inputs. In FFLD language, the input rung (EN) enables the operation, and the output rung keeps the same value as the input rung. In ILClosed "Instruction list" This is a low-level language and resembles assembly language, the MUL instruction performs a multiplication between the current result and the operand. The current result and the operand must have the same type.

Op1: FFLD  IN1
     MUL IN2
     ST  Q    (* Q is equal to: IN1 * IN2 *)
Op2: FFLD  IN1
     MUL IN2
     MUL IN3
     ST  Q    (* Q is equal to: IN1 * IN2 * IN3 *)
