Background/Objectives: In this paper a novel approach using the FAMPLC technique is presented as a solution for point to multipoint control and monitoring. A mathematical method for frequency optimization is also discussed. Methods/Statistical Analysis: A dedicated DC to AC inverter as a large signal integrated gateway for power and data in one side and multiple nodes each containing an active resistance as a dummy load on the other sides are considered to establish a distant bidirectional communication platform. A method in which the master unit is programmed to control and monitor the multipoint is discussed. Results: A mathematical approach for determination of the required frequency and the pulse width ranges are also offered. A compensative calibration sequence and a recommended communicating protocol are also presented. Conclusion/Application: The herewith presented model has been successfully developed and installed in the campus using 8 nodes in order to control and monitor the fire alarm system.
