Examples of device types are AlphaCom module, RIO, AlphaPro, Control Handler. All such devices have a unique device address when interconnected. The AlphaCom and AlphaPro have fixed device address, while the device address of e.g. a RIO is configured (inside the RIO) for the particular application.

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>.
<Device> is one byte.
Note that devices can both be physical boxes (e.g. RIO) or a function (Router).

Value (decimal) Value (Hex) Device Function
0 0x00 Invalid device (reserved NULL value)
1 - 64 0x01 - 0x40 External boxes. RIOs, PCs etc.
