Production process control and SCADA systems which based on computer usually handle some complex control process, such as concurrent execution control process, multi-path and multi-condition control process. Based on the current computer and communication technology development level, this paper realizes mixed flow sequential control by provides a method by using full configuration with daemon through upper computer in dispatch center. So that sequential control in lower computer can effectively reduce the shutdown time and operation accidents to achieve much higher reliability, and considerable economic and social benefits.
