在对实验模型的攻角控制中,使用可编程控制器PLC-200将常规半模控制与位置检测程序内置其中,通过EM277通讯模块,将该系统上挂于某型风洞PROFIBUS总线,使其升级为某型风洞DCS集散控制系统中的一个子系统,实现了某型风洞DCS系统中主控算机IPC对半模机构的远程控制与管理。
In the control of the attack angle of the experimental model, PLC-200 is used to integrate the conventional semi-mold control and position detection program into the PROFIBUS bus of a wind tunnel via the EM277 communication module It is upgraded to a subsystem in DCS distributed control system of a wind tunnel and the remote control and management of the half-mold mechanism by the main computer IPC in a wind tunnel DCS system is realized.
