Control unit for a machine

摘要

A control unit for a machine includes a processor and a memory for program instructions and parameter values. A first portion of the program instructions defines a first process which accesses the parameter values in order to ascertain control information and to transmit same to the machine, and a second portion defines a second process which evaluates the quality of the application data, and either permits or prevents the execution of the first process based on the evaluation results. The second process checks whether the value of at least one first physical parameter specified by the application data is valid and does not permit execution of the first process using these application data unless the value of the parameter has been determined to be valid.
