Output
Function
When the input is ON, the unsigned data of
A
is divided by the unsigned data of
B
, and the quotient is
stored in
C
and the remainder in
C+1.
The data range of
A
and
B
is 0 to 65535 (unsigned 16-bit data)

Example
When R010 is ON, the data of D0030 is divided by the constant data 300, and the quotient is
stored in D0050 and the remainder is stored in D0051.
If the data of D0030 is 54321, the quotient 181 is stored in D0050 and the remainder 21 is stored
in D0051.
D0030 54321
¸
RW27 181 (quotient)
Constant 300 RW28 21 (remainder)
Note
·
If divisor (operand
B
) is 0, ERF (instruction error flag = S051) is set to ON.
The ERF (S051) can be reset to OFF by user program, e.g.
-
[ RST S051 ]
-
.
·
If the index register K is used as operand
C
, the remainder is ignored.
·
This instruction handles the register data as unsigned integer.
