Abstract (en)

[origin: WO2020039395A1] An electronic circuit arrangement and a method are described for the remote transmission via wire of a digital signal emitted by an emitting device of an electrical state signal, associated with a plant in the field, to a remote processing unit of said digital signal. At the transmission end of a wired connection between the emitting device and a remote processing unit, a composite signal for transmission via wire is generated, comprising a signal portion representative of the logical state of the digital signal emitted by the emitting device and a signal portion for determining the electrical continuity of the transmission link. At a receiving end of the wired connection, a signal recognition electronic circuit that may be associated with the remote processing unit is arranged to receive the composite signal and to verify the existence of at least one change in the logical state of the composite signal within a time interval corresponding to a signaling period. The existence of at least one change in the logical state of the composite signal within a time interval corresponding to a signaling period is indicative of the integrity of the wired connection.
