Embodiment Construction
[0049] The present invention is very suitable for centralized real-time process controllers / regulators or relay protection systems with strict response time requirements and real-time processing systems using redundant configurations. The typical system architecture is as follows:
[0050] 1. Composition of multi-node acquisition and control system based on Ethernet
[0051] like figure 1 as shown, figure 1 It is a typical distributed acquisition control, data processing is centralized, control commands are issued centrally, and there is no data exchange between different data processing devices (hereinafter referred to as DPE). Data processing devices can perform independent functions or redundant configurations, depending on High-level application configuration and reliability considerations.
[0052] In the system, the acquisition and control device (hereinafter referred to as DAE) is responsible for process quantity acquisition and execution of input and output or mani...
