Paper Abstract

The local monitoring station is located in the bottom of Distributed Control System (DCS), which is connected to the producing objects directly and has high demand for real-time. The real-time of the local monitoring station can be improved from the point of communication subnet. Simplifying protocol is an important way to improve the real-time of communication subnet. The local process data of DCS is very short, and each basic controller in local layer is a relatively independent system, so the information that needs to be exchanged between controllers is not large. According to this characteristic, a kind of local monitoring station is designed in this paper, in which the communication mode is a master-slave mode and the protocol used is simplified. This type of communication subnet can perfectly improve the real-time of the local monitoring station.
