PROFINET is an open Industrial Ethernet standard developed by the PROFIBUS Organisation (PI). Based on Ethernet versatility, PROFINET make vertical integration of field level with Enterprise level easily. PROFINET is automation in real time, so it can cover all requirements of the Automation Industry. PROFINET is fit for factory automation, process automation, safety applications and motion control applications, etc.

PROFINET allows existing field bus systems such as PROFIBUS DP, PROFIBUS PA, AS-Interface, INTERBUS and DeviceNet to be integrated without changes to existing field devices. It means the investments of field devices and applications are all protected.

The PROFINET standard defines three different performance levels which cover the various requirements from different applications.

PROFINET NRT (Non Real Time): It uses standard protocols as UDP/IP. With response time approx. 100 ms PROFINET NRT targets for applications in process automation.
PROFINET RT (Real Time): For applications with higher requirements on cycle time like factory automation, it directly uses the Ethernet protocol to exchange I/O data, while diagnosis and configuration uses standard UDP/IP. PROFINET RT enables applications with response time approx. 10 ms.

PROFINET IRT (Isochronous Real Time): The highest requirements come from the control of complex industrial drive systems, like packaging machines or robotics. With applications with cycle time < 1 ms and jitter < 1 μs are possible.

Lead time: 5-7 working days from receipt of order.
