3. PROFINET FAQ

3.1 Does PROFInet provide intelligent field devices only on Ethernet?

In PROFInet structures, intelligent field devices, such as Simatic ET 200X with a CPU, can be connected not only to Ethernet but also to PROFIBUS.

 

3.2 Who supplies the Engineering Tool for PROFInet?

The multi-vendor engineering model of PROFInet allows automation manufacturers to develop their own engineering tools that can be used to configure components and devices from different manufacturers.

 

3.3 What is the difference between PROFInet and the concepts of IDA, IAONA and Ethernet/IP?

In general, all these concepts strive to achieve a distributed automation solution based on Ethernet.

PROFInet places the emphasis here on

 

- Reducing the time to market for mechanical engineers and plant construction companies by means of
  plant-wide engineering

- Integrating the fieldbus and Ethernet for the purpose of protecting customer investment

- Using IT mechanisms for supporting vertical integration

 

PROFInet not only specifies a communications model for totally integrated communication over the fieldbus and Ethernet but also a multi-vendor model for distributed automation with plant-wide, multi-vendor engineering.

 

Engineering model

The individual stations are programmed for PROFInet as before using the appropriate manufacturer-specific tools. This protects customers' investment in their own application software.

The distributed applications are then interconnected using a separate multi-vendor engineering tool.

The multi-vendor engineering model of PROFInet allows automation manufacturers to develop engineering tools for plant-wide engineering that can be used to configure components and devices from different manufacturers.

Fieldbus and Ethernet

PROFInet supports both pure Ethernet applications and combined fieldbus and Ethernet applications. The advantage of this is that in cases in which technical solutions do not exist for Ethernet, PROFIBUS can be used without the need to adapt the fieldbus protocol or field devices. An example of this would be Motion Control tasks or safety-related applications.The proxy concept means that other fieldbuses can, in general, also be integrated.

 

IT mechanisms

PROFInet uses the standard IT communication mechanisms in general use in the office environment. The use of the same communication mechanisms in the automation and office environments permits total integration of the different corporate levels (vertical integration).

 

Real-time for Ethernet, Web technologies

The further development of PROFInet is being pursued in PROFIBUS User Group working groups by, for example,

 

- Generating a real-time concept for Ethernet

- Integrating Web technologies for HMI

- Integrating process technology

- Defining interfaces to FDT

- Network management

 

3.4 Does PROFInet also function with other operating systems, such as Linux and Java?

The PROFInet concept is independent of the operating system. PROFInet stations can be implemented in any form provided that they comply with the PROFInet specification.

 

Extract from iee 11/2000:

"The runtime software was developed under the stringent requirement of operating system neutrality, to enable easy integration of the PROFInet core software in a wide range of embedded PLCs and systems by adapting it to the individual system - a specific operating system is not a prerequisite."

3.5 How can PROFInet be adapted to the current Microsoft developments (.NET)?

.NET is the Microsoft concept for future e-business applications and does not meet all the requirements of automation. COM/DCOM is well-proven in automation for communication applications (e.g. OPC).

The current Microsoft concepts will be taken into account during the further development of PROFInet.

3.6 With PROFInet, is it always necessary to install two bus systems locally, i.e. Ethernet & PROFIBUS?

Other concepts propagate distributed automation with a single communication medium connected from the office level through to the field level.

The PROFInet specification does not specify the physical characteristics of the transmission network. Pure Ethernet solutions as well as combined Ethernet and PROFIBUS solutions are possible. The strengths of PROFInet lie in the integration of both bus systems in a common concept.

The advantage of this is that in cases in which technical solutions do not exist for Ethernet, PROFIBUS can be used without the need to adapt the fieldbus protocol or field devices. An example of this would be Motion Control tasks or safety-related applications.

3.7 Is PROFInet a concept solely applicable to the field level?

PROFInet is a multi-vendor concept that ranges from the management level down to the field level which defines both the communication and a model for plant-wide engineering.

3.8 What is a proxy and how does the proxy concept operate in the case of PROFInet?

The proxy principle is part of the PROFInet specification and enables standard PROFIBUS slaves to be integrated into PROFInet concepts. The proxy acts as an intermediary in the communication process between stations on PROFIBUS.

It acts as a converter in the case of communication between stations on PROFIBUS and stations on Ethernet.
