OR_E
Outline
This function obtains the logical sum of two or more bits, and outputs it.
1. Format
*1.
Output variable
2. Set data
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
1) This function obtains the logical sum 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.
