0x10 Logical/Physical Node

Byte | AIB Field Description
--- | ---
2 | Address Element 0x10
3 | Data Length: 0x05
4-7 | Data[0-3] Physical Node ID (4 Bytes) Enter the hexadecimal value of the last four digits of the serial number on the chassis or EXNET-ONE card. For the CSP 2090 and CSP 2040, you can find the last four digits on the rear of the CSP. EXNET Connect® Because EXNET Connect® is a card within a PC chassis, you assign the physical node ID by: Using the serial number of the EXNET Connect® card for the last four digits of the serial number. Set the two most significant bytes to 0x0001. If the serial number of the user’s EXNET Connect® card was 0x03AD, in the Assign Logical Node ID message (0x10) define the value of the Physical Node ID field as 0x000103AD.
8 | Data[4] Logical Node ID Enter the ID you are assigning to the node. The default logical node ID of any CSP is 0xFF. When you use message 0x0010 to assign a logical node ID to a node, you must use the value 0xFF in the Logical Node ID field in the message header. The new logical ID is the value of Byte 8 in the AIB. To reassign a logical node ID, you must bring the EXNET® ring out of service.
