ROR (rotate right)

The ROR instruction rotates the DINT type input by NbR bits to right in a circular form and fills the bits on the left with the bits that are rotated.
Languages supported: Function block diagram, ladder diagram, structured text.
This instruction applies to the Micro810, L20E, L50E, and L70E controllers.

Description
EN
Input
BOOL
When set to true, the instruction is enabled.
  • TRUE: Execute the current computation.
  • FALSE: There is no computation.
Applies to ladder diagram programs.
IN
Input
DINT
Any integer value.
NbR
Input
DINT
Number of 1-bit rotations (in set [1..31]).
ROR
Output
DINT
Right rotated value. There is no effect if NbR <= 0.
ENO
Output
BOOL
Enables output. Applies to ladder diagram programs.
