(1) Divides BIN 16-bit data designated by
the result in the device designated by
(2) If a word device has been used, the result of the division operation is stored as 32 bits, and
both the quotient and remainder are stored; if a bit device has been used, 16 bits are used
and only the quotient is stored.
Quotient:
Remainder:
(3) Values for
S1
(4) Judgment whether values for
basis of the most significant bit (b15). (Sign is attached to both the quotient and remainder.)
• 0: Positive
• 1: Negative
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
the corresponding error code is stored into SD0.
• Attempt to divide
Program Example
(1) The following program divides "5678" by "1234" when X5 goes ON, and stores the result at
D3 and D4.
[Ladder Mode]
(2) The following program divides BIN data at X8 to XF by BIN data at X10 to X1B, and outputs
the result of the division operation to Y30 to Y3F.
[Ladder Mode]
(3) The following program divides, when X3 is turned ON, the data at X8 to XF by 3.14 and
outputs the operation result at Y30 to Y3F.
