Method and device for setting upper limit and lower limit of range dead zone of temperature signal, and DCS (Distributed Control System)

The invention discloses a method and a device for setting the upper limit and the lower limit of a range dead zone of a temperature signal and a DCS (Distributed Control System), and the method comprises the steps: adding a second execution logic after an existing first execution logic, and enabling the second execution logic to comprise a plurality of second sub-execution logics; each second sub-execution logic corresponds to a second sub-range obtained through division based on an initial range and a preset range dead zone, and setting of upper and lower limit dead zones of a temperature signal range is implemented through a second execution logic configuration building and packaging mode. The cost of re-investment in platform research and development is reduced, the expenditure of manpower and material resources is greatly reduced, the working difficulty of logic designers is reduced, and the application scene is expanded. 本发明公开了一种温度信号的量程死区上下限的设置方法、装置及DCS系统，通过在现有的第一执行逻辑后增添第二执行逻辑，第二执行逻辑包含若干第二子执行逻辑，每个第二子执行逻辑
