PROFINET Protocol Stack (CC-A / CC-B RT1)

PROFINET is realtime-enabled. It uses IT standards like TCP/IP and makes an integration into fieldbus systems possible. PROFINET was standardized by the IEC specifications IEC 61158 and IEC 61784. port offers an implementation of the PROFINET stack for slave devices with conformance class A / class B together with realtime class 1.

low resource consumption,usability with and without an (OS) operating systemhigh portabilityNEW: supports version 2.31 of the PROFINET specificationProvides the best conditions for the conformance testing of the PNOSupplied with embedded μIP UDP / IP stackSupport for (almost) all the TCP / IP stack by generic and Raw UDP socket connection

Overview

port offers a PROFINET slave stack implementation for conformance class A / class B as well as for Real-Time class 1.

port’s solution offers:

  • extrem low ressource requirements
  • can be operated w/o OS as well as with an OS
  • easy porting to other platforms
  •  Greatly simplified API: modules / slot configurations can be specified by API during initialization easy. 
  • use of a central callback function 
  • Implemented standard callbacks for all stack functions: they only implement desired deviations from the standard behavior. 
  • Better separation of platform-specific and platform-independent code 
  • standardization of the memory configuration for all supported platforms 
  • Platform-independent demonstration Example with data processing, LED and Button Support (if available on hardware) 
  • Numerous improvements in memory management, logging functions, etc.
  • Code Cleanup: You save a few hundred LOC with the same functionality.

Our experienced engineers support you with engineering services for implementation as well as with customer specific adaptations or extensions. port is supporting the customer from the very first trial until the product is certified.

 

 

Application

 

The PROFINET Protocol Stack provides all required services for a PROFINET IO compliant communication according to the IEC standards IEC 61158 and IEC 61784. It facilitates easy and fast development of PROFINET IO devices.

Access to the hardware is carried out via a hardware abstraction layer. Drivers are available for different CPU- and Ethernet controller with and without operating system. For fast bus access the Ethernet drivers are highly optimized.

With port’s multiprotocol FPGA solution also other Industrial Ethernet Protocols, e.g. EtherCAT, EtherNet/IP and POWERLINK can be integrated. An uniform user interface makes it easy to implement different protocols.

The PROFINET Protocol Stack is completely written in ANSI-C and can be compiled with every ANSI-C compliant compiler. Depending on the required scope of functionality the PROFINET Protocol Stack is available in different expansion stages. All versions of the PROFINET Protocol Stack are compatible to each other and are constantly tested with the current conformance test of the PNO for compliance with the standard.

The user application communicates with the PROFINET Protocol Stack through function calls and call-back functions.

Configuration and scaling of the PROFINET Protocol Stack is done with the help of the PROFINET Designtool. With it the PROFINET Protocol Stack can be tailored to an optimum to the available resources of the application. Besides the creation of the object directory all settings for the hardware can be carried out with it.

 

Description

 

The PROFINET Protocol Stack consists of a hardware independent and a hardware dependent part that communicate with message queues. The hardware dependent part consists of controlling software for the Ethernet MAC controller and timer functions.

The application communicates only with the hardware independent part of the PROFINET Protocol Stack. That way it is possible to exchange drivers without any influence on the functionality of the application. The initialization of PROFINET IO services is done with function calls within the application. During the execution of the application the PROFINET Protocol Stack executes all necessary communication tasks autonomously and informs the application about successful received PROFINET IO messages with the help of callback functions.

Communication requests from other devices as well as necessary periodical tasks and time out monitoring is handled within the PROFINET Protocol Stack. All requests are proved for correctness (access rights, data types etc.). The application is notified after completion of the communication and occurrence of failures, respectively, through service oriented callback functions. In these callback functions appropriate actions can be carried out from the application.

The high degree of scalability of the PROFINET Protocol Stack is of particular importance for devices with limited resources. On one hand, this is achieved by the modularity in individual service groups, and on the other hand, through the use of compiler directives in the respective modules. Thus, the code size is proportional to the utilized PROFINET services.

 

Scope of delivery

Delivery of the PROFINET Protocol Stack comprises different example programs that describe the usage of the various PROFINET services. All examples contain a complete implementation of a PROFINET IO device including the object directory as well as application code. These are ready to be compiled and run. Among the detailed documented source code there is the reference manual and a printed user manual as documentation available.

The PROFINET Protocol Stack is constantly improved and adopted to customer requirements. In order to keep up with the latest version of the PROFINET Protocol Stack port provides its customers an update service.

Licensing conditions (excerpt)

PROFINET Protocol Stack for one-time license fee in the form of a product / project or site license is collected. Further license fees do not arise from the deployment of the software within the same company (no runtime licenses). It is not allowed to hand over the software and the implementation, respectively, towards a third party.
