1. A method for operating a filling system, wherein the filling system has at least one first filling point and at least one second filling point, wherein the first filling point has at least one first filling valve, at least one first flow or fill level sensor and at least one first control and evaluation unit for controlling and monitoring the filling process of the first filling point, and wherein the second filling point has at least one second filling valve, at least one second flow or fill level sensor and at least one second control and evaluation unit for controlling and monitoring the filling process of the second filling point, wherein a valve curve of the first filling valve is stored in the first control and evaluation unit, and wherein a valve curve of the second filling valve is stored in the second control and evaluation unit, and wherein the first control and evaluation unit and the second control and evaluation unit are connected to one another via a communication channel, the method comprising:
in the operating state of the filling system, switching the first filling point to diagnostic mode;
reporting, by the first control and evaluation unit, the diagnostic start to the second control and evaluation unit;
outputting, by the first control and evaluation unit, substitute flow rate or substitute filling level values during the diagnostic mode;
transmitting, by the second control and evaluation unit, a deviation message to the first control and evaluation unit in the event of detection of a deviation of the current flow or level value from the flow or level value expected on the basis of the valve curve; and
after receipt of the deviation message, interrupting diagnostic mode and switching to normal operation, or outputting corrected substitute flow or substitute level values, by the first control and evaluation unit.
