2.1 Components of Industrial Communication Systems

Industrial automation systems consist of four main elements:

  • PLC Controller: The brain of the system, providing logic control, motion control, and process control functions
  • HMI Panel: Human-machine interface for operator command input and feedback output
  • Industrial Drives: Motor controllers that execute motion and action commands
  • Sensors: Real-time monitoring of system status and providing feedback data

These elements work together through communication networks to achieve efficient automated production.
