AND
Logical AND operation
To add an enable input and enable output to the instruction, select [With EN/ENO] from the
"Instructions" pane (LD, FBD or IL editor). To reuse an instruction select "Recently used" from the
context menu or press <Ctrl>+<Shift>+<v> in the programming window.
PLC types Availability of AND (see page 1335)
 All operands must be of the same data type.
 This function can be expanded to a maximum of 28 input contacts.
 Modifying elements
Data type I/O Function
BOOL, WORD, DWORD 1st input element 1 of logical AND operation
BOOL, WORD, DWORD 2nd input element compared to input 1
BOOL, WORD, DWORD output as input result
Input 1 Input 2 Output
0 0 0
0 1 0
1 0 0
Signal
1 1 1
Description
The content of the accumulator is connected with the operand defined in the operand field by a
logical AND operation. The result is transferred to the accumulator.

Example
In this example, the same POU header is used for all programming languages. For an example
using IL (instruction list), please refer to the online help.
POU header
All input and output variables used for programming this function have been declared in the POU
header.
Body
bvar_1 will be logically AND-linked with bvar_2. The result will be written into the output variable
bvar_3.
LD
ST
When programming with structured text, enter the following:
bvar_3:= bvar_1&bvar_2;
