8 Application Instructions API 100-149 API 111 Operands: S 1 : Lower bound of binary floating point S 2 : Upper bound of binary floating point S : Binary floating point comparison result D : Comparison result Explanations: 1. D occupied 3 consecutive devices. 2. S 1 ≤ S 2 . See the specifications of each model for their range of use. 3. S is compared with S 1 and S 2 and the result (>, =, D . 4. If S 1 or S 2 is andesignated constant K or H, the instruction will convert the constant into a binary floating point value before the comparison. 5. When S 1 > S 2 , S 1 will be used as upper/lower bound for the comparison. Program Example: 1.
Designated device M0 and M0 ~ M2 are automatically occupied. 2. When X0 = On. DEZCP instruction will be executed and one of M0 ~ M2 will be On. When X0 = Off, EZCP instruction will not be executed and M0 ~ M2 will remain their status before X0 = Off. 3. Use RST or ZRST instruction to clear the result. X0 M0 On when (D1,D0) > (D21, D20) M1 M2 On when (D1,D0) (D21, D20) (D11, D10) On when (D21, D20) > (D11, D10) Remarks: For floating point operations, see “5.3 Handling of Numeric Values”.
