Profinet IO

PROFINET is an open industrial Ethernet communication protocol proposed by the PROFIBUS & PROFINET International Association. PROFINET applies TCP/IP related standards and is a real-time industrial Ethernet. PROFINET has a modular structure, and users can choose cascading skills according to their needs.

The PROFINET IO system includes several parts: IO controller, IO device, and IO monitor. The IO controller is used to control the automation task; the IO device is generally a field device, controlled and monitored by the IO controller, and an IO device may include several modules and sub-modules; the IO monitor is a PC software that can set parameters and diagnose the status of individual modules.

TIP

Because the PROFINET IO real-time message uses the Ethernet protocol defined in PROFINET (real-time message is transmitted based on Ethernet frames), when using the PROFINET driver, you need to deploy Neuron directly with physical devices, and cannot use virtual deployment, such as Docker image or virtual machine.
