Mitsubishi MELSEC iQ-F FX5 series - Twos Complement of 16-Bit Binary Data (Sign Inversion)

282
6 BASIC INSTRUCTIONS
6.5 Data Conversion Instructions
Two's complement of 16-bit binary data (sign inversion)
NEG(P)
These instructions invert the sign of the 16-bit binary data in the device specified by (d), and store the resultant data in the
device specified by (d).
Setting data
■Descriptions, ranges, and data types
■Applicable devices
Processing details
• These instructions invert the sign of the 16-bit binary data in the device specified by (d), and store the resultant data in the
device specified by (d).
• They are used when a positive or negative sign is to be inverted.
Precautions
Note that data is inverted in every operation cycle in a continuous operation type (NEG) instruction.
Operation error
There is no operation error.
