METHOD AND APPARATUS FOR BUS FAULT LOCATION |
摘要 |
A bus fault location arrangement for locating the source of a fault condition on a bus connecting a plurality of devices energized by a power supply. When such a fault condition is detected, a bus diagnostic unit included in the arrangement transmits a signal to place a given one of the plurality of devices in a high impedance state. The bus diagnostic unit then transmits a given signal level on the bus. To determine whether the given device is the source of the fault condition, current flow between the device and the power supply is sensed and an error signal is stored when the sensed current exceeds a predetermined magnitude. |
