Designed with EdrawMax, this template illustrates the operation flow of a manual mode control system. Starting from "Start Manual Mode", it reads signals from a PLC via a push button, HMI, or web app. Based on the signal, actions such as turning on the cooling fan, heating and lighting, or using a motor to close the curtain are executed. Afterward, the device status is updated. The system then enters a loop, waiting for a new signal to repeat the cycle. This visual guide is useful for understanding the logic and operation sequence of a PLC - based manual control system.
