All ACDP data messages are addressed to a device. A device is always related to (owned by) a node. A full device address consists of <node> <device>.
<Node> is one byte.
| Value (decimal) | Value (Hex) | Node Type |
|---|---|---|
| 0 | 0x00 | Node 0 is interpreted by the exchange which receives it as "own node", and it will replace the value 0 with it’s own node number before processing takes place.
Response messages will thus NOT contain any node 0 references |
| 1 - 254 | 0x01 - 0xFE | Exchanges in AlphaNet |
| 255 | 0xFF | Broadcast to all nodes
- All AlphaNet nodes will re-send messages addressed to 0xFF to all other AlphaNet signaling links. - The Network layer manages broadcast messages to avoid excessive signaling traffic and discards messages that has jumped too many times. |
