摘要： An irrigation system comprises an irrigation controller that receives user input and provides a power signal and command and message data to an encoder. The encoder encodes the command and message data onto the power signal to provide a data encoded power waveform that is sent over a two-wire path. The irrigation system further comprises one or more decoders in communication with the two-wire path to receive the data encoded power waveform and one or more irrigation valves in communication with the one or more decoders. The data encoded power waveform provides power to the decoders and the decoders decode the command and message data from the data encoded power waveform to control the irrigation valves according to the user input.

摘要： A segment of a two wire combined power and data network for automation has a trunk, a spur mounted thereon and a fault protection device. The fault protection device includes a controller adapted to monitor the spur current, and isolation means to fully or partially isolate the spur from the trunk upon receiving of an activation signal from controller. The controller comprises a failure status determination algorithm comprising an intermittent fault count over time step and a fault duration step. The intermittent fault count step is satisfied if a pre-determined number of separate faults are detected over a first time period. The fault duration step is satisfied if a fault is detected which persists for longer than a second time period. The controller issues the activation signal upon determination of a failure status on the spur which satisfies the intermittent fault count and/or the fault duration step of the algorithm.

摘要： An isolated signal transmission apparatus isolatingly transmits, from a control-side apparatus to a control target apparatus, an electric signal obtained by superimposing a communication signal on a direct-current signal. The apparatus includes a lower limiter circuit configured to output, to the control target apparatus, a direct-current signal, whose value is a predetermined lower limit value, if a value of the direct-current signal from the control-side apparatus is less than the predetermined lower limit value.

摘要： Field devices are commonly used in unprotected environments, which means that these field devices and the conductor pairs connecting the field devices to the input modules/output modules of an automation installation are exposed to significant climatic and environmental factors. These factors have a detrimental effect on the transmission quality of the signals to be transferred between field devices and modules, which may result in erroneous measurements and dangerous operating states during control of a technical process. Measures to simplify monitoring of the transmission medium are proposed.
