-   Subtraction

Operator - Performs a subtraction of inputs.

Inputs

IN1 : ANY_NUM / TIME First input
IN2 : ANY_NUM / TIME Second input

Outputs

Q : ANY_NUM / TIME      Result: IN1 - IN2

Remarks

All inputs and the output must have the same type. 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 SUB instruction performs a subtraction 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

FFLD Language

(* The subtraction is executed only if EN is TRUE *)
(* ENO is equal to EN *)

IL Language:

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