Chapter 6 Applied Instructions Symbol: S ： Source value Word D ： Result Word Explanation: 1. The source value specified by S is a degree, and the instruction is used to get the tangent of the source value specified by S . After the tangent value is gotten, the sign is stored in D , the integer part is stored in D +1, and the fractional part is stored in D +2. 3. The operation result is rounded off to the fifth decimal place. 4. If the conversion result is 0, SM600 is ON. 2. The range of degrees: 0° ≦ Degree ＜ 360° Example: The instruction is used to get the tangent of the value in D0.
After the tangent value is gotten, the sign is stored in D10, the integer part is stored in D11, and the fractional part is stored in D12. BTAN D10 D0 Binary-coded decimal value Binary-coded decimal value D11 Binary-coded decimal value D12 Binary-coded decimal value Additional remark: 1.
If the value in S is not a binary-coded decimal value (The binary-coded decimal value is represented by the hexadecimal number, but one of digits is not within the range between 0 6-355 API Instruction code Operand Function 1521 BTAN P S, D Tangent of the binary-coded decimal 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 steps) 32-bit instruction AH500 AH500 - 0 0 6 0 0 0 0 0 0 0 0 1 7 3 2 0
