The logic interface engine 10 includes a logic controller 20 , a command router 30 , a message processor 40 , and a transport layer 50 . The logic controller includes a plurality of object classes that correspond to components of the command-driven device. The command router receives the outbound commands sent by the object classes, and inbound commands sent from the command inQueues of the command router, which the command router duplicates and forwards, as required. The message processor(s) each includes a corresponding host, message builder, and message splitter. The transport layer receives the outbound messages sent by the message processors and sends outbound messages to the logical communication channel. Additionally, the transport layer sends inbound messages to the message processors.
