By using virtual machines, known as workcells, to communicate with other virtual machines over a virtual network, creating complex event driven programs becomes very simple. For example, the USB port interface is completely autonomous and doesn't have an API. Instead, it interacts with other workcells by receiving three request messages, 'Read', 'Write' and 'Query' and transmitting 'Read' and 'Write' status messages.
This is based on the industrial automation programming model where complex machines interact using communication methods as simple as relay contacts.
