Profibus Master Mode

[ragıpselçuk]

I aim to design a controller with QorlQ . Controller feature shall be Profibus Master Support, Ethernet comminucation for remote control and other requirements. I searched all document But I found only profibus slave support for QorlQ devices.Feature list define Profibus Master but it is not enough.I have some question listed below.
      1- is QorlQ family support profibus master mode.?

      2- is it need a certificate or permission from Siemens A.G ?.

      3- How can I configure Profibus Master Nodes ?.

      4- is it possible a referance design for Profibus Master?.

      5- If I purchase TWR-P1025-KIT , can I make Profibus Master configuration and comminucation ?.

      6- What is the count of Profibus Master Nodes?

      7- is it support linux kernel profibus stack ?

      8- I know that it is possible to make with Profibus Master/Slave Card from third party companies compatible PCI-Express and a computer. It is very high cost solution.

I'd appreciate it if someone give answer my questions.thanks a lot.

1. 1. Look at the AN4877.pdf using the following link (http://cache.freescale.com/files/32bit/doc/app_note/AN4877.pdf).

3 and 5. Use the "Getting Started With Freescale PROFIBUS for PowerQUICC and" link on the page (http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=QORIQPROFIBUS&fsrch=1&sr=4&pageNum=1#).

3 and 4. The AN4877.pdf recommends using the TWR-P1025 and P1025 devices for PROFIBUS evaluation purposes only.

1. 6. Look at the following documents (http://een.iust.ac.ir/profs/Shahri/Computer%20Buses_84/PROFIBUS/PIC%20PROFIBUS%20Cabling%20Guide.pdf) and (https://w3.siemens.com/mcms/industrial-communication/en/support/ik-info/Documents/profn2_e.pdf).

1. 7. Look at the following document about Profibus stack (http://www.freescale.com/files/32bit/doc/fact_sheet/PROFIBUSFS.pdf)

1. 8. We do not have information about PCI express Profibus cards.

I am very grateful to you for detailed answer. I will check the documents.

I have last question. I know that molex , green hills, dogav are business partner. I wonder that is it need any certificate from this companies ?.

Do you know any community or group working about fieldbus low level driver ( profibus, profinet, ethernetIP ) for linux kernel, I want to join a group or community.

I look forward to hearing from you soon.

Thanks a lot.

Freescale offers the PROFIBUS master software. This software does not require any certificates..

Look at information about Linux driver for Profibus using the following documents (http://cache.freescale.com/files/training/doc/dwf/DWF13_AMF_NET_T0379.pdf) and (http://cache.freescale.com/files/32bit/doc/fact_sheet/MPC83XXECOMFS.pdf)

Hello Ragip SELCUK,

I just found some information about PROFIBUS for QorIQ and PowerQUIC.

QorIQ processors can be configured as either Master or Slave, and up to 125 slaves per master(one chip).

PROFIBUS Reference Platform supports

• PROFIBUS Slave certified by ComDec,  PROFIBUS certification lab hosted by Siemens AG
• PROFIBUS Master

P1025KIT contains image of complete PROFIBUS slave run-time software(including the layer 7 stack from TMG TE).

For detailed information about Profibus resolution, please refer to https://www.freescale.com/files/training_pdf/WBNR_FTF11_IND_F0376.pdf.

Thanks,

Yiping
