A control program for an industrial technical control system is created via a planning tool, wherein the control program includes program data that are assigned names by the planning tool, where beforehand, the planning tool checks the names of the program data of the control program via a checking routine for compatibility with the data processing device, and if the planning tool identifies an incompatibility by means of the checking routine, then it outputs a corresponding error message to the user, otherwise it outputs to the user either no message or a message indicating that no errors have been identified, and the planning tool receives an assessment of the control program from the data processing device and post-trains the checking routine based on the relevant control program and received assessment such that the checking routine gradually learns which names for the program data are compatible with the data processing device.
