Industrial Automation Protocols and Technologies

Industrial Automation

• Modbus is a industrial protocol that uses a master-slave communication architecture.
• CANbus is a wired communication protocol commonly used in industrial automation.

Communication Protocols

• Zigbee is a wireless communication protocol commonly used in IoT applications.
• Modbus is a widely used industrial communication protocol.
• HTTP is not an industrial communication protocol.
• OPC UA is a protocol that offers high-speed data transfer capabilities.

Industrial Automation Systems

• A Human-Machine Interface (HMI) is used to monitor processes in industrial automation.
• A Programmable Logic Controller (PLC) is a device used in industrial automation.
• A SCADA system is used for data acquisition, control of industrial processes, and alarm generation, but not for secure web browsing.

Controllers and Protocols

• A PID controller is used to regulate temperature, pressure, and flow rate in industrial automation.
• OPC UA is an open protocol that offers advantages in industrial communication.
• MQTT is a communication protocol commonly used for real-time control in industrial automation.

OSI Model and Communication

• The Physical Layer of the OSI model is responsible for defining the physical characteristics of the communication media.
• TCP/IP is a protocol that stands for Transmission Control Protocol/Internet Protocol.

Raspberry Pi

• The Raspberry Pi 4 Model B has the most GPIO pins.
• GPIO pins on a Raspberry Pi are used for digital input/output operations.
• The Raspberry Pi Zero has a small form factor and is suitable for industrial applications.
• The Raspberry Pi 3 Model A+ has more GPIO pins than the Raspberry Pi 1 Model A.

Thingworx

• Thingworx is a platform used for managing and analyzing data from connected devices.
• The Analytics Builder is a component of Thingworx used for managing and analyzing data.
• Thingworx is not an open-source platform.
• Thingworx is scalable, flexible, and secure.

Industrial Communication Protocols
