To enable self-reconfiguration, we propose a modified segment insertion bit (SIB) compliant to IEEE 1687. In this article, we propose a self-reconfiguring IEEE 1687 network in which all instruments that have detected faults are automatically included in the scan path, and a fault detection and localization module in hardware that detects the configuration of the network after self-reconfiguration and extracts the error codes reported by the fault monitoring instruments. Efficient handling of faults during operation is highly dependent on the interval (latency) from the time embedded monitoring instruments detect faults to the time when the fault manager localizes the faults.
