)
is shifted to the left by three digits
description
When the contact C300 is ON when this
instruction is executed,
Move all bits of address V525 to the left
by 3 bits:
Execution result: . 1 6 # 01 moves to the

10.1.35 ROR (cyclic right shift instruction )
IL programming
language
LD, FBD programming language
Function: The ROR instruction is used to cyclically shift the input value to the right.
LD IN1
ROR IN2
ST OUT
ST programming language
OUT:=ROR ( IN1 , IN2 )
Note : IL, ST language programming needs to insert variables IN1, IN2 and OUT or use
constants in the current POU variable worksheet
Data type processed by ROR instruction

ANY_BIT
Input
IN2 ( N )
ANY_INT
Number of bits shifted right
OUT
ANY_BIT
As a result, when the value of the pin IN or N changes,
it is shifted to the right. As follows : shift two bits to the
right
