A detection system for an agricultural header includes a belt that has at least one physical feature driven by a roller at a roller rotational speed. The detection system also includes a sensor that detects a physical feature as it passes the sensor during rotation of the belt. The detection system further includes a controller that receives a signal indicating a first pulse of a first time a physical feature passes the sensor during the rotation of the belt and a second pulse of a second time a physical feature passes the sensor during the rotation of the belt. The controller further determines a pulse frequency based on the first and second times and calculates a belt rotational speed based on the pulse frequency. The controller compares the belt rotational speed to the roller rotational speed and provides an output if the roller rotational speed exceeds a threshold.

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 an offset square wave of configurable frequency on the bus, and sends a synchronization pulse of selected duration at the start of each bus scan cycle in a pulse train cycle to reset counters in the field devices before the bus scan cycle is repeated, to ensure field devices are synchronized, transmitters transmit on the correct channel, and receivers sample the pulse cycle at the correct time. Changing the synchronization pulse length increases bandwidth for shorter, less noisy and more stable systems and inversely decreases bandwidth for increased noise immunity and distance for longer, noisier and less stable systems.
