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>.
