Operands
| Operand | Description |
|---|---|
| S1 | The first operand. Entries are DWORD data registers or constants. This is the dividend. The signed value range is -2,147,483,648 ~ 2,147,483,647 (232). The unsigned value range is 0 ~ 4,294,967,295 (232-1). The Hexadecimal value range is H00000000 ~ HFFFFFFFF. |
| S2 | The second operand. Entries are DWORD data registers or constants. This is the divisor. The signed value range is -2,147,483,648 ~ 2,147,483,647 (232). The unsigned value range is 0 ~ 4,294,967,295 (232-1). The Hexadecimal value range is H00000000 ~ HFFFFFFFF. |
| D | The third operand. Entries are only DWORD data registers. D is where the quotient is saved. There is no remainder. |
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.
WORD Result
There is NO remainder.
Tip: Operand Division Format
S1 is divided by S2. (S1 ÷ S2)
Ladder Diagram Examples
DWDIV
The DWDIV instruction divides a DWORD dividend value, S1, by a DWORD divisor value, S2, and saves the quotient in an assigned DWORD data register, D.
When the contact, M0.0, is powered ON, the DWORD data register, D2, is divided by the DWORD data register, D4, and the quotient is saved in the DWORD data register, D6.

DWDIVP
The DWDIVP one-shot instruction divides a DWORD dividend value, S1, by a DWORD divisor value, S2, and saves the quotient in an assigned DWORD data register, D. Every time this instruction executes, it energizes the output only once.
When the contact, M0.0, is powered ON, the DWORD data register, D2, is divided by the DWORD data register, D4, and the quotient is saved in the DWORD data register, D6.
