An Addressable Electronic Switch (AES) is disclosed together with unique S/W (software) procedures for a system control to detect, locate, and isolate shorts, overloads, and other troubles, such as temporary breaks or disconnects, on a Vplex or similar 2-wire polling loop. The addressable electronic switches are placed at strategic locations throughout the polling loop, and are individually commanded by the system control to either connect or disconnect its respective branch from the rest of the polling loop, to locate and isolate a troubled area from the rest of the polling loop.
