Abstract

The invention relates to a device ( 10 ) for at least one industrial automated process ( 110 ), in particular a weighing and/or packing and/or arranging and/or packing process, comprising: at least one sensor ( 30 ) for determining at least one process data value which is relevant to the entire process by detecting at least one partial process parameter of the device ( 10 ), which parameter is relevant to the entire process, a processing device ( 40 ), which is electrically connected to the sensor ( 30 ) for processing the process data value, an interface device ( 50 ) for data connection and for forwarding the process data value to at least one individual machine ( 2 a, 2 b, 2 c ) located upstream and/or downstream in the process ( 110 ), wherein the total process ( 110 ) can be evaluated with reference to the process data value by comparison with a pre-defined process instruction ( 130 ).

a sensor for determining an overall-process-relevant process data value, relevant to the process, through a detection of an overall-process-relevant sub-process parameter of the device, wherein the overall-process-relevant sub-process parameter is a measured variable on the device,
a processing device which is electrically connected to the sensor for the processing of the overall-process-relevant process data value, and
an interface device configured for a data connection and forwarding of the overall-process-relevant process data value to an upstream individual machine located upstream in the process,

wherein
the processing device of the device is configured to evaluate the process through a comparison of the overall-process-relevant process data value with a predefined process default in order to detect deviations or errors based on the overall-process-relevant process data value,
the device comprises a data storage unit that is non-volatile and configured for persistent data storage in order to store the determined overall-process-relevant process data value permanently,
the predefined process default comprises a comparison value for the overall-process-relevant process data value,
the comparison value defines a range of values, and
wherein the processing device of the device is configured to control the entire process adaptively, such that:
the processing device of the device is configured to initiate a warning sequence, if, according to plausibility checks, a deviation of the overall-process-relevant process data value from the range of values is determined, and
the processing device of the device is configured to initiate the warning sequence upon determination of a negative evaluation result, and configured to request or evaluate an operator input to adjust the comparison value.

2. The device according to claim 1 ,

a) determining the overall-process-relevant process data value in a downstream sub-process, and
b) checking the plausibility of the overall-process-relevant process data value outside of an upstream sub-process such that the overall-process-relevant process data value is compared with the comparison value, whereby an evaluation result specific for the process is established in order to detect deviations or errors based on the overall-process-relevant process data value,
c) evaluating the upstream sub-process based on the evaluation result adaptively,
d) permanently storing the overall-process-relevant process data value in a process recording, and
