PROFINET

IO-Link is the smart concept for the standardized connection of sensors and switching devices to the control level by means of a low-cost, point-to-point interface. This enables a central diagnosing and locating of errors down to the sensor/actuator level. Commissioning and maintenance are considerably easier to implement since parameter data can be dynamically changed directly from the application.
Using the ET 200eco PN IO-Link Master, intelligent IO-Link devices can be easily connected directly to the distributed ET 200eco PN IO without the need for a control cabinet.

The new PROFINET Truck is on a tour of Europe. You can get to know the Truck in a film that is available for download in English and German from our homepage. If you want to learn more about the PROFINET Truck, please contact your Siemens partner in the region.

PROFINET IO also allows safety-related signals (e.g. emergency-stop motor) to be exchanged between the ET 200 distributed IO and a SIMATIC S7-CPU. For some applications, wireless communication (IWLAN) is the more cost-effective solution. In some cases, it is the only option, e.g. for communication between mobile or difficult-to-access areas in an automation system. A new use case describes this solution. To this end STEP 7 code can be downloaded free of charge.

Many SIMATIC controllers, e.g. CPU 319-3 PN/DP, the PROFINET-CPUs of the S7-400, the new PROFINET-CPU of the ET 200S and the new SIMATIC S7 modular embedded controllers, now communicate by means of high-speed IRT (isochronous real time). High-speed communication is used predominantly in larger machines and process cells, if numerous nodes are interconnected on a linear basis with very short update times. Or if the same network is used for PROFINET communication and parallel standard communication, e.g. TCP/IP, with a high volume of data.

The PNIODiag diagnostics package simplifies the analysis of distributed IO modules with SIMATIC S7-CPUs – both for PROFIBUS DP systems and for PROFINET IO systems. The diagnostics package contains a function block for the S7-CPU and visualization for WinCC flexible in German and English.
