This instruction compares the content in S 1 and S2. Take API232 (AND =) for example, if theresult is “=”, the continuity of the instruction is enabled. If the result is “≠”, the continuity of theinstruction is disabled.2. AND※ (※: =, >, <, <>, ≤, ≥) instruction is used for serial connection with contacts.API No. 16 -bitinstruction32 -bitinstructionContinuityconditionDiscontinuitycondition232 AND＝ DAND＝ S1＝S2 S1≠S2233 AND＞ DAND＞ S1＞S2 S1≦S2234 AND＜ DAND＜ S1＜S2 S1≧S2236 AND＜＞ DAND＜＞ S1≠S2 S1＝S2237 AND＜＝ DAND＜＝ S1≦S2 S1＞S2238 AND＞＝ DAND＞＝ S1≧S2 S1＜S23. When the MSB (16-bit instruction: b15, 32-bit instruction: b31) of S1 and S2 is 1, the comparisonvalue will be viewed as a negative value in comparison.4. When 32-bit counters (C200 ~ C254) are used in this instruction, make sure to adopt 32-bitinstruction (DAND※). If 16-bit instruction (AND※) is adopted, a “program error” will occur andthe ERROR indicator on the MPU panel will flash.Program Example:1. When X0 = ON, and the content in C10 = K200, Y20 = ON2. When X1 = OFF and the content in D0 ≠ K-10, Y21= ON and latched.AND= K200 C10 Y20AND<> K-10 D0 SET Y21X1X0
