 Precautions for Correct Use

The input variables are not allowed to omit. An error will occur during the compiling of the software if
any input variable is omitted. But the output variable is allowed to omit.

The value of Out is the same as In when the value of Num is 0.

The number of bits by which the bits of data are rotated to the right is equal to the value of Num
MOD In when the value of Num is greater than the number of bits of the value of In.
For example, if the data type of In is BYTE, the value of out when Num=USINT#1 is the same for
when Num=USINT#9.

Programming Example

The data types of ROR_In and ROR_Num are UINT and USINT respectively and their values are
300 and 3 respectively. The data type of Out1 is BYTE and the value of Out1 is 32805 when
ROR_EN is TRUE.
