how to use ethernetip_adapter code transfer data (am3359 icev2)

Other Parts Discussed in Thread: AM3359, SYSBIOS

Hi Guys,

I want to use the am3359 ice v2 board to transfer data through ethernet/ip protocol and get the command from upper level app also through ethernet/ip protocol. Now all the low level code has been finished(such as ADC sample, digital input/output and so on) and now it's time to transfer the data. But it seems I totally lost these days(I am a new man in the ethernet/ip communication field). Can anyone give me some suggestions, any documentation or any application notes? Can anyone point me to the right direction? 

For example, I added the ADC sample code into the ethernerip_adapter example code and want to send the measured data from ADC through ethernet/ip protocol. How can i modify the ethernetip_adapter code so that I can send the data through the ethernet/ip protocol?

I am very appreciate your help and thank you so much!

Regards,

Aaron

    Hi Aaron,

    Could you provide some more details ? EtherNet/IP is just CIP implemented over plain EtherNet and TCP/IP. You can find lots of resources on the web, especially if you go to ODVA's website.

    Are you talking to some EtherNet/IP controller or node using the AM3359 ? Otherwise you can send data using just TCP/IP as well, it's a lot simpler if the usage is outside an industrial setup.

    To send data through EtherNet/IP you will have to use the EtherNet/IP stack (from Molex) for creating IO data packets. Since the stack provided with the SDK is a third party stack and only an evaluation version, to get more information you will have to go to Molex's website and download all necessary documentation.

    Hi Vineet,

    Thank you so much for your help. Am3359 is used to talk to eWON which is an industrial router. The eWON's document said it support the Ethernet/IP protocol. Now I think I know the direction. By the way, are there any sample code or open resource code for sending data using TCP/IP by am3359?

    Thanks and have a good day!

    Hi Aaron,

    as Vineet pointed out, using TCP/IP would be less complicated.

    Providing that would suite you, there is a link in the user's guide of the ICEv2 board (the one that mentions Ethernet/ip) how to strip the EthernetIp example.

    The following threads cover problems that arised when the Ethernetip example was adapted to plain Tcp/Ip in a TIRTOS project:

    e2e.ti.com/.../1404124
    e2e.ti.com/.../406303
    e2e.ti.com/.../395190

    Hope that helps.

    Hi Martin,

    Thank you so much for your help. I followed the introduction to strip the EthernetIp example and used the XGCONFIG to configure the NDK. The NDK was set to use the static IP address: 192.168.1.2 and I build it and I tested it.  I connected the board to my PC and ping the address and It seems that it work, result showed below:

    Now, I want to move forward. I want to make a simple test that send the AD sample result to my PC through the ethernet. Here are my XGCONFIG for NDK:

    Here are questions:

    1) what kind of terminator do I need for the test?

    For example, if I test the UART communication with my PC, I use the terminator:  Tera Term, so that I can see the data sent form my board to PC and also I can use it to send data to my board.

    2) How to modify the code? What kind of API  functions can i use? 

    For example, I have a global variable to store the AD sample result. If I use the UART, I use the function UARTPutChar() to send data to my PC and use UARTGetChar() to get data from my PC.  And also do I need to add the hook functions? 

    3) Do you have some sample code for this? And where can I find the EchoTcp() example code? It is not in the SDK package.

    P.S.: Now i just want to build a very simple test, using the AD module to sample a analog input and then send it to my PC so that I can see the data.

    Thanks and have a good day and hope to hear from you! 

    Regards,

    Aaron

    Hi Aaron,

       You can make use of NDK sockets to send data to PC. Industrial SDK does not provide basic TCP/IP  examples. Please refer to the sample applications in   NSP (NDK Support package) to get more info on basic NDK examples.

    "Hercules SETUP utility by HW-Group.com" is a program I am quite happy with when it comes to checking connections. It is freeware.

    The EchoTcp example can be found in
    "User's Guide, TI Network Developer's Kit (NDK) v2.24", Literature Number: SPRU523I

    Good luck!

    Download this file "AM335x SYSBIOS Industrial SDK 01.01.00.06 User Guide.pdf" and there is introduction on how to modify Ethernet/IP to work as switch application.
