When Num =2, all bits of the value of In are shifted by two bits to the left and the values of Bit0~Bit1 are
supplemented with 0 and Bit6~Bit7 are discarded as shown in the following figure.

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.

Programming Example

The data types of SHL_In and SHL_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 2400 when
SHL_EN is TRUE.
