The invention relates to a sequence control method between scheduling and telemechanics based on an IEC61850 standard and belongs to the electric-power-system telemechanical communication equipment technology field. According to the IEC61850 standard, the method adopts a controllable integer state common data type INC to realize interval state control and adopts an integer state common data type INS to store an interval state value, an operation step value and an operation result. The controllable integer state INC and the integer state INS common data type are combined together so as to construct one sequence control logic node. The sequence control logic node realizes interval four state control conversion. By using the method, a sequence control function between the scheduling and telemechanics based on the IEC61850 standard can be effectively realized.
