CHAPTER 3. COMPONENTS AND TECHNOLOGIES USED
3.2
PROFInet Stack
”Softing Protocol IP for PROFINET is a combination of IP cores and Industrial Ethernet
device protocol software designed to offer all required communication capabilities for an
implementation based on the Altera FPGA.” [19] There can be used various industrial
communication protocol with the stack while all use the same programming API called
SDAI-Simple
Device
Aplication
Interface.
According to documentation [3][19] it can be used for:
• Verify the functionality of available protocols.
• To learn about the protocol integration.
• To integrate the protocol into field devices.
• To work as a PROFInet, PROFInet RT/IRT device.
The package contains:
• Documentation
• IP core license
• Real time ethernet switch IP core
• Other utility IP cores
• NIOS II project and source code
• NIOS II software project
• NIOS II demo application
• SDAI code and documentation
There is a 2 hour evaluation period timer, which block the functionality after the timer
expires. This is for the users to test the functionality without buying the product. After
purchase the timer is disabled. For our development we were using this evaluation feature.
According to [19] the stack is compliant with PROFInet version 2.3, GSDML version 2.31
and PROFIdrive version 4.1.
