Operands
| Operand | Description |
|---|---|
| S1 | The first operand. Entries are WORD data registers or constants. This is the dividend. The signed value range is -32,768 ~ 32,767 (216). The unsigned value range is 0 ~ 65,535 (216-1). The Hexadecimal value range is H0000 ~ HFFFF. |
| S2 | The second operand. Entries are WORD data registers or constants. This is the divisor. The signed value range is -32,768 ~ 32,767 (216). The unsigned value range is 0 ~ 65,535 (216-1). The Hexadecimal value range is H0000 ~ HFFFF. |
| D | The third operand. Entries are only DWORD data registers. D is where the quotient is saved. D+1 is where the remainder is saved. |
Notice
Error Flag (F11.0) Notice
The error flag, F11.0, will be ON for one scan when the address of the data register assigned by @D exceeds the range of the data register, D. The range of the data register, D, is dependent on the CPU type. F11.0 turns ON when the value of the data for dividing exceeds the data register assigned to S1 or S2. F11.0 turns ON when the value of the divisor, S2, is 0.
Tip: Operand Division Format
S1 is divided by S2. (S1 ÷ S2)
Ladder Diagram Examples
DIV
The DIV instruction divides a WORD dividend value, S1, by a WORD divisor value, S2, and saves the result in an assigned DWORD data register, D. The quotient is saved in the data register, D, and the remainder is saved in the data register, D+1.
When the contact, M0.0, is powered ON, the WORD data register, D1, is divided by the WORD data register, D3, and the result saved in the DWORD data register, D5. The quotient is saved in the data register, D5, and the remainder is saved in the data register D6.

DIVP
The DIVP one-shot instruction divides a WORD dividend value, S1, by a WORD divisor value, S2, and saves the result in an assigned DWORD data register, D. The quotient is saved in the data register, D, and the remainder is saved in the data register, D+1. Every time this instruction executes, it energizes the output only once.
When the contact, M0.0, is powered ON, the WORD data register, D1, is divided by the WORD data register, D3, and the result saved in the DWORD data register, D5. The quotient is saved in the data register, D5, and the remainder is saved in the data register D6.
