A method for operating an automation field device comprises connecting a two-conductor line with an input terminal of the field device; setting a minimum electrical current value at the input terminal of the field device in an initializing phase; measuring a maximum voltage value at the input terminal in the initializing phase; ascertaining a minimum supplemental power supplied to the field device at the input terminal and which is available to the field device for performing at least one supplemental functionality; and activating/switching on a supplemental module by the processing unit when the ascertained minimum supplemental power is greater than or equal to an operating power needed for operating the supplemental module, wherein by the activating/switching on of the supplemental module a corresponding supplemental functionality is performed by the field device in measurement operation.

Method for operating an automation field device

A synchronous data transmission system for transmission of data between two communication partners, of which one serves as a transmitter and one as a receiver, comprising a clock signal producer which produces a transmission clock signal with a transmission clock signal rate from the transmitter to the receiver, which during the occurrence of one of the events equals an event specific transmission clock signal rate associated with the arising event and during an event free period of time equals a fundamental clock rate different of all event specific transmission clock signal rates.

Synchronous data transmission system

An electronic device, and a method for executing a plurality of processes with the electronic device, wherein, in a resource-conserving manner, rapid response times are achievable, in that the electronic device, during operation, executes first and second processes (P, P), of which the first processes (P) are executable as approximate solutions (P-A) and as detailed calculations (P-C). The electronic device includes a processor for executing processes (P, P) and an electronic unit or a multitasking-capable operating system. The electronic unit includes a component, which recognizes whether the processor is active, and serves, while the processor is active and a simultaneous execution of at least two processes is required, for executing the first processes (P), in that it, itself, determines the approximate solution (P-A) and sets such in the place of a detailed calculation (P-C) determined with the processor.

Electronic device and method for performing multiple processes with the electronic device

A method for start-up and/or operation of a communication system composed of at least one multivariable sensor, at least one converter unit and at least one receiving unit, which are connected with one another via a two-wire line. A wherein a primary measured value in the form of an analog signal and extra measured values in the form of an encoded digital signal modulated on the analog signal are provided from the multivariable sensor via the two-wire line, wherein only analog signals are received by the receiving unit. The extra measured values are scaled in the multivariable sensor into formatted values by means of a conversion algorithm, wherein at least the formatted values are requested and received by the converter unit, and wherein corresponding analog signals of the extra measured values are produced from the formatted values in the converter unit by a fixedly predetermined, unconfigurable, reconversion algorithm. The analog signals of the extra measured values are transmitted via respective separate electrical current lines to the receiving unit.
