10 Application Instructions API 202-313 API 221~ 223 Operands: S 1 : Data source device 1 S 2 : Data source device 2 Explanations: 1. See the specifications of each model for the range of operands. 2. This instruction compares the content in S 1 and S 2 . If the result is not “0”, the continuity of the instruction is enabled. If the result is “0”, the continuity of the instruction is disabled. 3. OR# is an operation instruction used on parallel contacts. 4. &: Logical “AND” operation 5. |: Logical “OR” operation 6. ^: Logical “XOR” operation 7. When 32-bit counters (C200 ~ C255) are used in this instruction for comparison, make sure to adopt 32-bit instruction (DOR#).
If 16-bit instructions (OR#) is adopted, a “program error” will occur and the ERROR indicator on the MPU panel will flash. Program Example: 1. When X1 = On and the result of logical AND operation of C0 and C10 ≠ 0, Y10 = On. 2. M60 will be On when X2 = On and M30 = On, or the result of logical OR operation of 32-bit register D10 (D11) and 32-bit register D20 (D21) ≠ 0, or the result of logical XOR operation of 32-bit register D200 (D201) and 32-bit counter C235 ≠ 0.
