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 WORD 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
WDIV
The WDIV instruction divides a WORD dividend value, S1, by a WORD divisor value, S2, and saves the quotient in an assigned WORD data register, D.
When the contact, M0.0, is powered ON, the WORD data register, D10, is divided by the WORD data register, D12, and the quotient is saved in the WORD data register, D14.
Memory Monitor
WDIVP
The WDIVP one-shot instruction divides a WORD dividend value, S1, by a WORD divisor value, S2, and saves the quotient in an assigned WORD data register, D. Every time this instruction executes, it energizes the output only once.
When the contact, M0.0, is powered ON, the WORD data register, D10, is divided by the WORD data register, D12, and the quotient is saved in the WORD data register, D14.
