Abstract

Background/Objectives: To introduce a novel achievement in distant access to an I/O port using Frequency and Amplitude Modulations in Power Line Communication (FAMPLC) technique. Methods/Statistical Analysis: FAMPLC is a platform for large signal communication over a power line. A Frequency Modulated Power Supply (FMPS) as a power and data gateway to supply and communicate with the remote (slave) module is developed, which is called the Master (or server) module. The transmission procedure from the slave node to the master unit is performed by use of an active resistance as a dummy load to overlay pulses onto the consumer’s current. Results: The experimental outcomes of a full – duplex 16 bits (8× 8) extended remote I/O module without the requirement of any localized power supply and with the distance range enhancement, up to twelve kilometers are presented throughout this paper. Conclusion/Application: A full-duplex development of a remote I/O module is presented. With this development, an unshielded pair of wires may be used and longer distance range can be achieved.
