Abstract:
A method for a plug and play polling loop system comprised of a plurality of product devices such as sensors in different zones of the polling loop system which are controlled by a system control, comprising:prewiring all of the product devices to the polling loop, wherein during installion a zone address for each product device, which is derived from a polling loop site plan, is set by a person installing the device by setting an n-bit DIP switch; enrolling all of the prewired product devices connected to the polling loop, during which the system control uses serial number (S/N) group global polling protocols for global polls of the S/Ns of a number of product devices at one time; for each of the unique S/Ns thus obtained, the system control follows with a S/N unit poll to receive from the product its associated zone address, such that the control automatically enters all of the unique S/Ns and their associated zone addresses into its data base.
