In a method for diagnosing control system of a process engineering plant having a plurality of actuating units for setting a process fluid and a central unit, at least one actuating-unit-specific control raw datum, such as a setpoint value, an actual value, a setpoint-actual difference value, or a control value, is detected; a particularly local diagnosis code is generated by one of the plurality of actuating units based on the at least one detected control raw datum; the diagnosis code is transmitted from the actuating unit to a central unit; a local diagnosis code, is transformed into a global diagnosis codes; a logical condition for a diagnosis deduction logic is defined such that when the logical condition is applied to at least one diagnosis code, the diagnosis deduction logic determines a predetermined deduction result; and a deduction result is determined based on the at least one diagnosis code.
A method for diagnosing a control and/or regulation system of a process plant having a central unit and a plurality of control devices configured to adjust a process fluid, the method comprising:
