The invention relates to a system and a method for identifying automation components, particularly sensors, actuators and wiring components. According to the invention, each component (sensor, actuator, cable, compensation box, etc.) that is to be identified is equipped with an identification unit in which a code for identifying the automation component is stored and which outputs said identification code when being activated. Preferably, the identification unit comprises an electronic circuit (e.g. an RFID chip or a discreet circuit) while being provided with galvanically insulating (inductive, capacitive, radio-based) or galvanically conducting coupling to the component that is to be identified. The identification unit can be subsequently mounted on a component or can be inseparably connected thereto already during the production of the component.

System and method for identifying automation components

An automation system and a method for identifying and correcting connection errors of field devices that are connected to an automation system are provided. A connecting unit is used to optionally connect field device connections of an automation system with connections of a feed or measuring component of the automation system.

Automation system and method for identifying and correcting connection errors

In a protective power supply, several isolated D.C. voltages are generated by separate inductive transformers, the primary windings of which are arranged in parallel in the diagonal branch of a bridge circuit which has electronic switches controlled in push-pull manner and arranged in two bridge arms. The transformer windings for the protective power supply provided for transistor pulse converters have a low coupling capacity and a small resistance.

Switched power supply for generating a plurality of isolated power

A method and device for data transmission over several parallel lines, in particular over optical fibers is described for transmitting measured values from a measuring station arranged at a high-voltage line to an evaluating electronic system at a high data rate, a high utilization of the available transmission lines, preferably optical fibers, is desirable. To this end, via a clock line, clock messages are relayed which are separated from each other by a synchronization interval (P2) and which begin at least with a fixed clock message portion (PT), which may preferably be followed by a freely usable clock message portion. The receiver recognizes each message start by the synchronization interval of the clock messages and forms during the fixed clock message portion synchronous sampling pulses, which may be followed by asynchronous sampling pulses for the duration of the free clock message portion. The transmitter can now send via data lines data messages which begin synchronously with the fixed clock message portions and need not contain any fixed programmed pulses for the recognition of telegram messages.
