Hi,
We are using Anybus on our Xilinx based embedded systems to communicate with PLC. We may have up to 7 of these systems on the same ethernet segment. I’ve looked thought the code and it seems that FW on all our systems using the same MAC address. It does not create any problems so far, but I’m just wondering what is best way to handle MAC addresses in this case?
Thank you,
Mike
Hi @makopyan ,
This question might be better suited for a case on mysupport.hms.se so we can check with some of the developers. I am not well versed in the Xilinx IP, but the standard host application allows you to set the MAC ID in the Ethernet Object (0xF9) object in abcc_identification.h.
Hi,
Just to clarify: my question is not “How to set MAC address in Xilinx SW”, but rather: “Should we set different MAC address on each Xilinx systems if they connected to the same PLC?”
Thank you,
Mike
Yes, a MAC should be unique. A general ethernet networking rule is that the MAC addresses for each device on a LAN is unique.
