In traditional factories, machines and operators communicate using simple protocols such as Gantt charts. However, these methods of communication are often ineffective, leading to errors and delays.

On the other hand, smart factories use cutting-edge technology such as radio frequency identification (RFID) tags and sensors to communicate in real-time. This means information can be passed between machines and operators instantaneously, which helps avoid errors and increase efficiency.

By implementing the following communication technologies, smart factories can further increase the output of smart manufacturing lines:

• RFID tags are used to identify and track products and materials as they move through the factory.

• Sensors collect data on every aspect of production, from machine performance to operator productivity.

• IP cameras can monitor the production process in real-time, which helps to identify errors and optimize operations.

• Wireless networks provide a fast and reliable portal for machines and operators to communicate with each other via systems and wireless devices.
