$2 = F100H

$4 = NOT $2

Store the result of $4 in 0EFFH

 << Operand

Bit Shift-left operation

Equation: V1 = V2 << V3

Shift V2 (WORD/DWORD) data to left (number of bit is V3). The result of this calculation is

stored in V1.

Example:

$2 = F100H

$1 = $2 << 4

$2 shift-left 4 bits and the result (1000H) is stored in $1.

$2 = 11111000

$1 = $2 << 3

$2 shift-left 3 bits and the result (11111000000) is stored in $1.

 >> Operand

Bit Shift-right operation

Equation: V1 = V2 >> V3

Shift V2 (WORD/DWORD) data to right (number of bit is V3). The result of this calculation is

stored in V1. If the shift number of bit is more than the address itself, the excess part will be

ignored.

Example:

$2 = F100H

$1 = $2 >> 4

$2 shift-right 4 bits and the result (0F10H) is stored in $1.

$2 = 00011111

$1 = $2 >> 3

$2 shift-right 3 bits and the result (00000011) is stored in $1.

 Data Transfer

There are five commands for data transfer, including =, BMOV, FILL, CHR and FMOV. Please refer to

following table 4.3.3 and examples below for more information.

Command Equation: Description Remark

V1 = V2

Transfer data

V1 only can be PLC address

or internal memory.
