I think you mention about a part of value except for node ID. In my former example (0xFFC74567), it's 0x4547. You mean that Fireface 400 ignores the part and sends transactions to the fixed local address (i.e. 0x'0001'0000'0000). Although, this is against the fact that I got in my experiences with Fireface 400. The model can reasonably send transactions to the address which the driver registered. Regards Takashi Sakamoto
