Abstract:
1. A method for connecting an AC current detecting device with an automation controller network device via an optical grid of an optical cable for propagating one way optical signals, said network device comprising a CPU, a communication circuit and a first optical receiver, said AC current detecting device comprising a CPU, a communication circuit, a current sensing circuit and a second optical transmitter for detecting an AC current drain by a load and said load status; an optical element of each optical receiver and each optical transmitter is enclosed in an opaque socket with an optical access and a holder commensurate with a size and a shape of a terminated end of said optical cable, said method comprising the steps of: a. terminating one said optical cable at its both ends by a process selected from a group comprising cutting, shaping, polishing, lapping, fitting a plug and combinations thereof for providing a processed surface at both ends of the optical cable; b. attaching and securing the two processed surfaces of each said terminated end one to each said optical element directly via each said opaque socket by each said holder; c. introducing to at least one of said CPU an identification pertaining to at least one of said load and said AC current detecting device; d. connecting said load to an AC power through said AC current detecting device; e. operating said load; f. detecting by said current sensing circuit the current drained by said load and said load status; and g. propagating said one way optical signal including said identification and reporting at least one of the load current drain and the load status via said grid.
