Intelligent controller and sensor network bus, system and method including a message retransmission mechanism

A machine automation system for controlling and operating an automated machine, the system comprising:

• a controller and sensor bus including:
• at least one central processing core including one or more root ports each having a root acknowledgment engine;
• one or more transmission networks each including a plurality of leaf nodes and directly coupled to the core via a different one of the root ports, the leaf nodes each including a leaf acknowledgment engine and a leaf node memory;
• and
• a plurality of input/output ports each coupled with one of the leaf nodes;
• and
• a plurality of external machine automation devices each coupled to one of the leaf nodes via one or more of the ports coupled with the one of the leaf nodes;
• wherein:
• one of the root ports transmits a grant message indicating a transmission window to one of the leaf nodes coupled with the one of the root ports;
• the one of the leaf nodes transmits a data message including a plurality of packets having destination information and an acknowledgment request indicator to one of the root ports within the transmission window and the leaf acknowledgment engine of the one of the leaf nodes stores a leaf copy of the data message including the plurality of packets;
• and
• if the one of the root ports receives the data message without any uncorrectable errors, the root acknowledgment engine of the one of the root ports transmits a data-received message to the one of the leaf nodes which removes the leaf copy based on receiving the data-received message.
