Abstract:
An input/output (I/O) and control system for long distance communications and industrial applications having a bus and protocol for communications between field devices and a channel generator for monitoring and control of the field devices. The channel generator produces a pulse train such as an offset square wave with dual scan bus cycles having alternating A and B scan cycles that each comprise a plurality of channel windows assigned to the field devices. One or more channel windows in the A and B scan cycles has an exception interrupt window during which the control unit can detect a low level signal provided by a field device before its corresponding channel window in the dual scan bus cycle, thereby reducing system reaction time.

Claim (Index 9):
A method of implementing a bus protocol for interfacing a control unit to plural devices connected to the bus comprising:\n generating a pulse train comprising a plurality of cycles for transmission on the bus, each of the cycles comprising a first voltage level portion for a designated period of time and a second voltage level portion for a designated period of time that indicates a space, at least some of the cycles corresponding to respective channel windows assigned to respective ones of the plural devices, each of the plural devices being able to indicate a state to the control unit by changing voltage on the bus to a different voltage level during the first voltage level portion of its channel window and the channel unit responding by delaying a rising edge of the second voltage level pulse a selected amount of time in the channel window to indicate a mark; wherein the pulse train employs at least one scan bus cycle comprising the channel windows and at least one of control bits and synchronization bits, the plural devices and control unit are synchronized to ensure that the plural devices transmit and receive during their corresponding channel windows and that, when the control unit samples the pulse train during the channel windows, the control unit associates the samples to the corresponding ones of the plural devices, and the at least one scan bus cycle is employed to indicate in the channel windows corresponding to each of the plural devices any one of two states selected from the group consisting of Device ON, Device OFF, Fault and No Device using binary combinations of a mark and a space in the channel windows of the at least one scan bus cycle that are assigned to a selected one of the plural devices, and the at least one scan bus cycle further comprises at least one exception pulse among the channel windows, the exception pulse providing an interrupt exception window and having a selected voltage level portion during which the control unit can detect a change in voltage on the bus provided by at least one of the plural devices during the pulse train but outside of its assigned channel window.
