What protocol is commonly used for Siemens communication between devices?

The protocol commonly used for Siemens communication between devices is PROFINET. PROFINET is an industrial Ethernet standard specifically designed to facilitate communication for automation engineering and control systems. It is widely adopted within Siemens products and offers robust functionality, such as real-time communication, high data transfer rates, and the ability to integrate various devices and systems seamlessly.

PROFINET enables devices from different manufacturers to communicate efficiently, promoting interoperability within the industrial environment. Its support for both standard Ethernet and real-time control enhances its usability for various applications. This makes it a preferred choice in Siemens’ automation solutions, where reliable and fast communication between controllers, sensors, and actuators is critical for maintaining operational efficiency.

While other protocols like Ethernet/IP, MODBUS, and CANopen also serve their specific purposes in industrial communication, PROFINET stands out in Siemens ecosystems due to its comprehensive features tailored for automation processes, making it the most relevant choice in this context.
