10 Application Instructions API 202-313 API 287~ 292 Operands: S 1 : Source device 1 S 2 : Source device 2 Explanations: 1. EH2/SV_V1.9 and versions above, and EH3/SV2 supports the function. EH series does not support the dunction. 2. This instruction compares the content in S 1 and S 2 . Take API287 (FOR =) for example, if the result is “=”, the continuity of the instruction is enabled. If the result is “≠”, the continuity of the instruction is disabled 3. The user can specify the floating point value directly into operands S 1 and S 2 (e.g. F1.2) or store the floating 4. OR ※ ( ※ : =, >, , ≤, ≥) instruction is used for parallel connection with contacts.
point value in D registers for further operation. Program Example: When both X2 and M30 are OFF and the content in D100 (D101) ≥ F1.234, M60 = ON.
