Communication TCP/IP via SPI et ENC28J60H Ethernet

[buissonth]

Bonjour à tous,

Je cherche à ajouter un port Ethernet à ma SB-RIO 9605 et dialoguer en Modbus TCP avec un appareil sur un autre réseau que celui de ma SB-RIO.

J’ai donc acheté un ENC28J60-H qui communique via le protocole SPI sur le FPGA de la SB-RIO.

Comment puis-je rendre le protocole de communication SPI transparent sous LabVIEW et donc dialoguer en TCP/IP sur mon réseau sur lequel le module ENC28J60-H est branché ?

Je souhaite en quelque sorte réaliser un tunnel entre ma SB-RIO connectée au réseau A et mon réseau B.

Merci par avance pour votre aide

Cordialement

My apologies for responding in English, but my French is limited to Google Translate 🙂

Currently, I'm not aware of a method to tunnel a virtual NIC through the FPGA via a SPI interface to a PHY or any other means.  With a good bit of work, you may be able to get the SPI interface to your PHY working, but it won't be possiblet to get a native (yellow block) TCP/IP function to speak to your driver on the FPGA.

As you have worked with the RMC connector, you have probably seen a number of reserved pins. It may be possible to use some of these reserved pins to route processor Ethernet pins to a PHY on your RMC.  This wouldn't be a direct off the shelf solution, and it would require invesitgation and development on both your end and from NI.  I recommend you contact your local sales engineer to determine if this would be a good solution for you to pursue.  Because of the complex nature of this custom solution and the work that NI would have to do to support this, it may require a large minimum purchase commitment from you or NRE to fund the development.

Hope this helps.
