5.5 Standard Bitwise Boolean Functions
5.5.1 AND_E
Outline
This function obtains the logical product of two or more bits, and outputs it.
1. Format
*1. Output variable
2. Variable
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
1) This function obtains the logical product using each bit of bit/word [unsigned]/bit string [16-bit]/double
word [unsigned]/bit string [32-bit] data stored in devices specified in and , and outputs the
operation result to a device specified in using the data type of data stored in devices specified in
and .
Example: When the data type is word [unsigned]/bit string [16-bit]
2) The number of pins in can be changed.
Cautions
When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different from
simple projects. Use labels when handling 32-bit data. You can specify 32-bit counters directly, however,
because they are 32-bit devices.
Use global labels when specifying labels.
