Abstract
A process measuring device including: A first processor, which performs a measured value processing with a first algorithm in first processing cycles; and a second processor, which is responsible for coordination and/or communication tasks. The second processor reads, in time intervals which are greater than the first processing cycle, a control data set from the first processor, and executes the first algorithm on the basis of the control data set, in order to verify the correct functioning of the first processor.
Claims10
A process measuring device, comprising:
- a first processor, which performs a measured value processing in first processing cycles with a first algorithm;
- and
- a second processor, which is responsible for coordination and/or communication tasks, wherein:
- additionally, said second processor, in time intervals, which are greater than the first processing cycle, reads a control data set from said first processor;
- and
- on the basis of the control data set, executes the first algorithm, in order to verify correct functioning of said first processor.
