The purpose of this document is to specify the Data link, Network and Application layer of the AlphaCom Data Protocol. • The protocol is used for communication in an AlphaCom Network that may comprise several AlphaCom and TouchLine exchanges. • The protocol is also used between the AlphaCom exchange and external devices, such as Remote I/O boxes, PC based Control Handler systems etc. The Data Protocol is made generally available from software version AMC 06.00. Previous AMC softwares are NOT compatible with this protocol document.

The following concepts are commonly used in the document: Module: One AlphaCom “card cage”, contains up to 26 circuit boards (such as ASLT, AMC, APC, AGA). Exchange: Up to 4 AlphaCom modules interconnected in a master/slave configuration. One of the modules plays the role as a master, while the other modules are slaves. Communication with the world outside (if other devices are connected) is via the master. Node: The address of an Exchange. If several exchanges are interconnected (via the AlphaCom Data Protocol), then each exchange will have a unique node number. Device: 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.
