A measuring arrangement for redundantly determining a quantitative value of a current flow includes a first and second current-measuring modules connected in parallel, where the first current-measuring module includes a first analogue input and a first current measurement resistor and a voltage-measuring unit to determine the value of current flowing into the analogue input and through the first current measurement resistor, the second current measuring module includes a second analogue input and a second current measurement resistor and a voltage-measuring unit to determine the value of current flowing into the second analogue input and through the second current measurement resistor, and includes a control unit that detects a gradual change in voltages determined by the voltage-measuring units, and when gradual changes in the voltages that are counter to each other occur, a current-measuring module is excluded from the determination of the quantitative value of the current flow.

Redundant current-measuring arrangement with detection of interruptions of an electric circuit

An apparatus, method for operating an automation device which includes a processor for directly executing function modules, where a function module selected as a component of an automation solution via a development environment, is converted into a code block via the development environment, where the code block includes a type identifier corresponding to the type of the particular function module, where inputs and outputs of the particular function module are mapped to simultaneously usable processor registers in the code block, a plurality of code blocks is processed by reading-in a particular code block by the processor and subsequently executing the code block to execute the automation solution, and where execution of the code block includes selecting a function unit from a plurality of function units based on the type identifier of the code block and activation of the selected function unit with the processor registers specified in the code block.
