1. A method for data communication between a management level and a field level of an industrial system, the management level controlling processes of the industrial system, comprising:
providing a data communication module, the data communication module connected to both a management level application on the management level and a field device on the field level such that data communication takes place between the management level application and the data communication module and between the field device and the data communication module;
receiving, by the data communication module, a data query from the management level application on the management level to the field device on the field level;
transferring, by the data communication module, the data query from the management level application to the field device;
receiving, by the data communication module, response data from the field device to the data query;
checking, by a checking module of the data communication module, a data quality of the response data, wherein checking the data quality includes considering whether the response data corresponds to the data query and/or whether the response data is in a predetermined data format in which the response data should be structured;
performing, by the checking module, a corrective measure in order to correct the response data when an insufficient data quality is ascertained in the checking; and
transferring, by the data communication module, the response data or the corrected response data to the management level application for use in controlling processes of the industrial system;
wherein checking by the checking module of the data communication module occurs prior to transferring by the data communication module the response data or the corrected response data to the management level application, and
wherein the checking the data quality of the response data further comprises comparing, by the checking module, the response data with a set of rules, wherein the set of rules define individually tailored quality requirements for response data from respective field devices, and wherein response data from the respective field devices that deviate from the individually tailored quality requirements defined in the set of rules are interpreted as response data of insufficient quality.
