Abstract: This paper implements a design of time-sequence control system based on PC104 by using below PC104 embedded controller in combination with an upper industrial computer. In the design, PC104 controller works black-box mode to finish the time-sequence task which has higher real-time demand. Ethernet communication is applied between the upper computer and the PC104 controller, and remote monitor is achieved by the upper computer. Application results show that this system has the features of high reliability, high real-time, flexible configuration and strong function restructure, and it can provide reliable time-sequence control for sub-system.
