    摘要： Disclosed is a field device adapter for wireless data transfer for connection to a field-device-internal interface provided for a display, comprising: an interface for connection to the field-device-internal interface; a radio module configured to wirelessly transmit a data packet on a low-power wide-area network, wherein the radio module is further configured to only transmit the data packet and not to receive any data packets; adapter electronics configured to limit an energy provided via the field-device-internal interface to a predefined value and to charge a stored energy source with the limited energy. The adapter electronics are further configured to monitor a state of charge of the stored energy source and, based on the state of charge, to provide the radio module with an energy originating from the stored energy source for transmitting the data packet.

    摘要： An input/output module for a programmable controller is provided. The input/output module has a digital input channel, and in order to prevent power losses previously incurred internally within the module, an electrical source is provided internally within the module for evaluating the status of a sensor connected to the digital input channel. The module receives no electrical energy via the digital input channel but outputs it. A reduction is thus achieved in the power loss incurred internally within the module. A method for operating an input/output module for a programmable controller is also provided.

    摘要： An analog input unit as an analog unit attached to a PLC includes an A/D converting unit as a first converting unit performing conversion between an analog value and a digital value according to a first conversion characteristic, a shared memory as a retaining unit retaining a conversion characteristic table indicating a second conversion characteristic of conversion between digital values, and a conversion processing unit as a second converting unit converting a digital value according to the second conversion characteristic by referring to the conversion characteristic table. The conversion characteristic table includes combinations of a first value that is a digital value and a second value that is a conversion result of the first value, the number of which corresponds to resolution of a digital value in the analog unit, and the second value of each of the combinations of the first value and the second value can be adjusted.

    摘要： A programmable controller with an I/O signal converting circuit having an input element and an output element, comprises a signal I/O unit having a plurality of element sockets capable of replaceably accommodating both the input element and the output element; a selecting unit for selecting the type of the accommodated element; and a signal storing and sending unit. Each element socket may accommodate the input and output elements. Therefore, the space required to install the I/O circuits is reduced, and the number of input and output elements can be arbitrarily set.

    摘要： The present invention has the following characteristics.The process input signal input value and engineering unit value scale data are associated and stored inside the control unit. The operation value determined from the input value and the engineering unit value scale data are sent from the control unit to the monitoring unit. Accordingly, the control unit and monitoring unit do not hold separate engineering unit value scale data, so the engineering unit value scale data can be centrally managed.
