A recently granted patent (Publication Number: US11906222B2) discloses a method for testing the functional stability of a controller of a refrigerating machine. The method involves connecting the controller to a diagnostic unit for data exchange during operation. The testing method includes a recording step and an execution step carried out by the diagnostic unit. The recording step involves associating a progressive value with a recording cycle identifier and recording a set of reference data, while the execution step involves initializing the controller with the reference data values for input and status variables.

Furthermore, the testing method includes a comparison step where the output variables recorded during the recording step are compared with those recorded during the execution step. The method also involves a preliminary setting step where the controller's memory data is organized in pages and transmitted to the diagnostic unit. The patent specifies the technical specifications of the controller, including RAM capacity, ROM capacity, CPU clock speed, and serial communication port, ensuring efficient testing of the refrigerating machine controller's functional stability.
