ABSTRACT:
A control system uses a wireless mesh network to provide communication between a host computer and field devices. The host and the field devices communicate with one another using wireless messages containing requests and responses that are routed through the wireless mesh network. The wireless messages include sequence information that allow the receiving device to identify and reject messages that are received out of order.
