What are the most common types of PLC control systems?

Programmable Logic Controllers (PLCs) are widely used in industrial automation to control and monitor various processes. Consequently, there are different types of PLC control systems based on their architecture, capabilities, and application-specific features. Here are some of the common types:

PLC systems fit any application

PLC Control Panel
  • PLC with Human-Machine Interface (HMI) integrates a graphical user interface for operators.
  • SCADA (Supervisory Control and Data Acquisition) Systems combine PLC control with data acquisition and monitoring capabilities.
  • Robotics Control Systems coordinate the movements and actions of robotic arms and end-effectors.

Types of PLC Control Systems

  • Sequential or Basic Relay Logic Control is ideal for basic sequential tasks, like conveyors.
  • Batch Process Control is for controlling batch processes like mixing, heating, and cooling.
  • Continuous Process Control is used in industries with continuous production processes.
  • Discrete Manufacturing Control is used in discrete manufacturing environments such as automotive manufacturing or electronics assembly.
  • Motion Control Systems offer precise control of motion and are specialized for applications such as robotics or CNC machines.
  • Distributed Control Systems (DCS) are employed in large-scale industrial processes with distributed control.
  • Safety PLCs implement safety functions and ensure safety standards compliance.
  • HVAC Control Systems control temperature, humidity, and airflow in buildings or industrial facilities.
  • Building Automation Systems (BAS) integrate various building systems such as lighting, security, and environmental controls.
  • Pump and Motor Control Systems are designed for the control of pumps and motors.

PLC System for Water Treatment Plant

Use standardized symbols for components, sensors, and actuators in a PLC system diagram when outlining processes for a water treatment plant. Connect them with lines to show signal flow and logic. Try tools like Visio or similar software.

Operation:

Water Intake

Water enters treatment plant, if level is low, PLC activates pumps to bring in water.

Treatment Process

The PLC program controls the dosage of chemicals based on sensor feedback in different treatment stages. Additionally, valves monitor water flow and pressure for efficiency, while directing it through treatment units.

Quality Monitoring

Sensors measure water quality and if parameters deviate from acceptable ranges, alarms trigger via PLC.

Distribution

Water is treated, stored, and distributed based on demand with pump and valve controls by a PLC.

Emergency Response

PLC triggers alarms and initiates emergency procedures for anomalies or emergencies such as pump failures and water quality issues.

Application: Water Treatment Plant

Components of the PLC System:

PLC systems are widely used in various industries for automation and control purposes. Here’s an example of a PLC system in a typical industrial application, such as a water treatment plant:

  1. PLC Hardware:

    • PLC Controller: A CPU executes the control program.
    • Input Modules: Modules monitor water sensors for level, flow, and pressure.
    • Output Modules: They control devices like pumps, valves, and alarms.
  2. Sensors and Actuators:

    • Water Level Sensors: These sensors monitor the water levels in different tanks.
    • Flow Meters: Measure the flow rate of water in various pipes.
    • Pressure Sensors: Monitor pressure levels in the system.
    • Pumps: Actuators that pump water through the treatment process.
    • Valves: Control the flow and direction of water.
  3. Control Panel:

    • Human Machine Interface (HMI): A user interface that allows operators to monitor the system, view status, and make adjustments.
    • Operator Input Devices: Buttons, switches, and touchscreens for manual control and data input.
  4. PLC Programming:

    • Control Logic: The PLC program contains logic to control the operation of pumps, valves, and other devices based on input from sensors.
    • PID Control: Proportional, Integral, and Derivative control algorithms for maintaining optimal process conditions.
