D
This instruction inverts a BIN oating point format number which is designed by into its negative value and
stores the result back into .
When X0 = “OFF” → “ON”, this instruction performs the positive/negative inversion operation on the BIN oating
point number in (D1, D0), and then the result will be stored back into (D1, D0).
This instruction is a 32-bit instruction. Therefore, be sure to input DENEG or DENEGP in the program.
D
The operand must assign to a BIN oating point number for the calculation.
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.
