PROFINET slave stack：profinet从站协议源码
port offers a PROFINET slave stack implementation for conformance class A as well as for
Real-Time class 1 and the Real-Time class UDP. 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.
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.
