Such devices or units can be attached to form an homogenous systems called stack. The invention provides a set of rules to handle such stack. The rules are controlled by the architectural component named Unit Manager. The Unit Manager uses a protocol to discover the units that are entering or leaving the system/stack. The protocol's data provides a unique way of identifying the units that belong to the system stack.
