3 Basic Instructions Program Example: Ladder diagram: Instruction code: Operation: X0 X1 Y1 LD X1 Loading in contact A of X1 OUT Y1 Driving Y1 coil Note: DVP-EH3 series PLCs whose version is 1.40 and DVP-SV2 series PLCs whose version is 1.20 support the operands X, Y, M, and S. These operands can be qualified by E or F, e.g. ANI X0E1. Explanations: The OR instruction is used in the parallel connection of A contact. The functions are to read out the status of present designated parallel connection contacts and perform the “OR” operation with the logical operation result obtained. The final result will be store in the accumulative register. Program Example: Ladder diagram: Instruction code:
Operation: LD X0 Loading in contact A of X0 X1 Y1 X0 OUT Y1 Driving Y1 coil Note: DVP-EH3 series PLCs whose version is 1.40 and DVP-SV2 series PLCs whose version is 1.20 support the operands X, Y, M, and S. These operands can be qualified by E or F, e.g. OR X1E1. Explanations: The OR instruction is used in the parallel connection of B contact. The functions are to read out the status of present designated parallel connection contacts and perform the “OR” operation with the logical operation result obtained. The final result will be store in the accumulative register.
