mod / modLR / modR

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Calculation of modulo.

Inputs

Input	Data Type	Range	Unit	Default	Description
IN	mod = DINT modR = REAL modLR = LREAL				Input value.
BASE	mod = DINT modR = REAL modLR = LREAL				Base of the modulo.

Outputs

Output	Data Type	Range	Unit	Description
Q	mod = DINT modR = REAL modLR = LREAL			Modulo: rest of the integer division (IN / BASE).

Remarks

None

FBD Language

FFLD Language

• In the FFLD language, the input rung (EN) enables the operation.
  • The output rung keeps the state of the input rung.
  • The comparison is executed only if EN is TRUE.
  • ENO has the same value as EN.

IL Language

• In the IL "Instruction list" This is a low-level language and resembles assembly language, the first input must be loaded before the function call.
  • The second input is the operand of the function.

Op1: LD "Ladder diagram"
Ladder logic is a method of drawing electrical logic schematics. It is now a very popular graphical language for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical "rails" and a series of horizontal "rungs" between them  IN
     MOD BASE
     ST  Q    (* Q is the rest of integer division: IN / BASE *)

ST Language

Q := MOD (IN, BASE);
