Devices
When X0 = “OFF” → “ON”, the dividend (D1, D0) will be divided by the divisor (D3, D2), and the quotient will be
stored at the destination device (D11, D10). The components used in the instruction which are all stored in the
BIN oating number format.
S2
This instruction is a 32-bit instruction. Therefore, be sure to input DEDIV or DEDIVP in the program.
If a source operand is assigned to a constant integer K or H, this instruction will automatically convert the number
to BIN oating point number for the calculation. Therefore, could execute the division function.
The format for storing a oating point number will occupy two Registers in the PLC system. Please refer to the
section 2-13 “Numerical System” for the reference of the oating point number.
If the value of divisor is equal to “0”, the PLC will regard that as an operational error.
