摘要： A polling loop system provides all products to be prewired to the polling loop by technically unskilled labor followed by a plug and play enrollment process. The system combines the advantages of DIP switch zone addressing with smart serial number (S/N) addressing, which simplifies installation and replacement requirements. The system is fully backward compatible and is intended for a next generation of commercial polling loop systems.

摘要： 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.

摘要： A Vplex polling loop device is disclosed which can automatically detect and isolate shorted or overloaded sections of a polling loop, before or after polling loop power and signaling is switched to the output of the device, permitting normal operation of the remaining portion of the polling loop. The Vplex short and overload isolator (VSOI) is usable on former, existing, and future polling loop systems without the need for any software or hardware changes to the associated controls, and may also be used on 2-wire DC voltage distribution systems within the voltage and current limits of the VSOI. It is capable of multiple use anywhere on a polling loop while requiring minimum power from the polling loop. Finally, in the process of detecting and isolating a short or overload on its output, it prevents that short or overload from causing other VSOI devices on the loop to erroneously disconnect their protective branches of the loop.
摘要翻译：公开了一种Vplex轮询环路设备，其可以在轮询回路功率和信令切换到设备的输出之前或之后自动检测和隔离轮询回路的短路或过载部分，从而允许轮询回路的剩余部分的正常操作。 Vplex短路和过载隔离器（VSOI）可用于前一个，现有和未来的轮询回路系统，而不需要对相关控制进行任何软件或硬件更改，也可用于内部，电压和电流极限的VSOI。它能够在轮询循环的任何地方多次使用，同时需要轮询循环的最小功率。最后，在检测和隔离其输出端短路或过载的过程中，可以防止短路或过载导致环路上的其他VSOI设备错误地断开环路的保护支路。
