Chapter 6 Applied Instructions API 1503 Symbol: S ： Source value Double word D ： Arcsine value Double word Explanation: 1. Arcsine value=sin -1 The relation between sine values and arcsine values are shown below. 2. If the conversion result is 0, SM600 is ON. Example: When X0.0 is ON, the arcsine of the floating-point number in (D1, D0) is stored in (D11, D10). The arcsine value in (D11, D10) is converted into the degree, and the conversion result is stored in (D21, D20). The degree in (D21, D20) is converted into the integer, and the conversion result is stored in (D31, D30).
The integer in (D31, D30) is converted into the binary-coded decimal value, and the conversion result is stored in Y0.15~Y0.0. 6-329 Instruction code Operand Function FASIN P S, D Arcsine of the floating-point number Device X Y M S T C HC D L SM SR E PR K 16# “$” DF S D Pulse instruction 16-bit instruction (5-6 steps) 32-bit instruction AH500 AH500 -
