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 FBD
"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 IL "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.
ST Language
Q := IN1 * IN2;
FBD Language
(* the block can have up to 16 inputs *)
FFLD Language
(* The multiplication is executed only if EN is TRUE *)
(* ENO is equal to EN *)
IL Language:
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 *)
