MOD(_E)
Outline
This function performs division using two values (A / B = C
…
remainder), and outputs the remainder.
1. Format
*1.
Output variable
*2.
Refer to the Cautions
2. Set data
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
This function performs division (
/
) using word [signed]/double word [signed] data stored in devices
specified in
and
, and outputs the remainder to a device specified in
using the data type of
data stored in devices specified in
and
.
Example: When the data type is word [signed]
Cautions
1) Use the function having "_E" in its name to connect a bus.
2) 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.
3) Note that the "MOD" description method is different from other function description methods in the ST
language.
