Automation and Ethernet Communication09 Feb 2011 06:00 am

Wecome to Omron PLC Center ,Today i would like to present about PROFINET,PROFINET falls under the umbrella of the Ethernet communication.

In the world of information technology, Ethernet has almost 40 years and the concept of Ethernet has developed into what we today take for granted has grown as a common technology in our daily lives.

But in recent years, we have the migration of Ethernet communication in process control and motion control applications seen. This new technology allows for faster communication, strict control circuits, and advanced diagnostics, which ultimately lead to higher productivity. Although there are still lines in the sand, between the worlds of IT and industrial automation, these lines fade, when the two domains that have started their experiences and knowledge. It is extremely important for the company to enhance cooperation between the two organizations to promote, because there is much to learn and many financial benefits that may arise.

PROFINET IO is designed for Real-Time (RT) and Isochronous Real-Time (IRT). It is designed to exchange data between Ethernet field devices, encoders, sensors and laser sensors and industrial controls, drives and SCADA systems easier. The following example shows that the position and speed information generated by an encoder. This information is then made available to be consumed on the network of PROFINET controller or other devices that need this information. Only devices that consumers can request information, ignoring other critical IT and process packages just for her. The use of general Station Description (GSD) files, the characteristics of a given device. This makes the construction of communication packets to pass parameters, cyclic data exchange and alert updates. (more…)

This information hasn’t attack or partial with products and company but we presents information for your benefit.
In automation, there is no standard for communication today.
Each manufacturer uses its own protocol. Now start with TCP / IP as a means of exchanging data.
They developper to the design of protocols based on TCP. I do not know what one will be widespread. One criteria for openness.
Before comparison between Modbus/TCP,Ethernet/IP and ProfiNet ,we should be to understand for each communication standards.
PROFINET is the open Industrial Ethernet standard of PROFIBUS and PROFINET International (PI) for automation. PROFINET uses TCP / IP and IT standards and are, in reality, real-time Ethernet.

The Profinet concept is modular, so users can freely choose overlapping functions. They differ primarily because of the nature of the exchange of data with the sometimes very high speed. (more…)
