A logical program to control a start/stop push button and manage output operations.

• Use a PLC to monitor the state of the push buttons.

• Implement a simple state machine: Idle, Running, Stopped.

• When 'Start' is pressed, transition to 'Running' state and activate output.

• When 'Stop' is pressed, transition to 'Stopped' state and deactivate output.

• Example: Use a relay to control a motor based on the state.

Input and output are signals that are used to communicate between the PLC and external devices.

• Inputs are signals received by the PLC from sensors or other devices.

• Outputs are signals sent by the PLC to actuators or other devices.

• PLC processes the input signals and generates the output signals based on the program logic.

• Examples of inputs include switches, sensors, and analog signals.

• Examples of outputs include motors,...read more
