Which protocol is commonly used for communication between FANUC robots and PLCs?

Ethernet/IP is a widely used protocol for communication between FANUC robots and Programmable Logic Controllers (PLCs). This protocol operates over standard Ethernet networks, enabling fast and efficient data transmission between devices. Its popularity stems from its ability to support a large number of devices on a network while facilitating real-time data exchange, which is crucial for industrial automation applications that require precise coordination between robots and PLCs.

Using Ethernet/IP allows for easy integration of robots into existing network infrastructures, making it a preferred choice for manufacturers looking to implement advanced automation solutions. Additionally, this protocol supports both I/O messaging and explicit messaging, offering versatile communication options that enhance the functionality of robotic systems in industrial settings.

In contrast, other protocols like CANopen are primarily used in automotive and industrial applications requiring different architectures, while RS232 is an older serial communication standard that lacks the speed and versatility of Ethernet/IP. Bluetooth, while useful for short-range wireless communications, is generally not suitable for the real-time demands and data volume required in industrial robotics applications.
