Type of sequence control

Basic sequence control is divided mainly into three types that are sequence control, condition control and time limit control. Design the target control circuit by a combination of these control types.
1. Sequence control
Sequence control is the most basic of control types. With sequence control, the following operation is started in a predetermined order when the previous fixed operation ends.



2. Condition control
With condition control, an operation is performed when specific conditions are satisfied by combining various information and signals.



3. Time limit control
With time limit control, timers or similar counting devices are used, and the next operation is performed when a fixed time has elapsed.
