Diagnosis of Physical-Layer Bus Parameters in a Filling Level Measuring Device

A filling level measuring device for connection to a field bus, comprising:

• a processing unit being adapted for monitoring a signal which is intended for being one of (a) transmitted from the device to a further device connected to the field bus and (b) received by the device from the further device,
• wherein the processing unit is further adapted for determining at least one physical layer parameter of the signal.

A pressure measuring device for connection to a field bus, comprising:

• a processing unit being adapted for monitoring a signal which is intended for being one of (a) transmitted from the device to a further device connected to the field bus and (b) received by the device from the further device,
• wherein the processing unit is further adapted for determining at least one physical layer parameter of the signal.

A flow measuring device for connection to a field bus, comprising:

• a processing unit being adapted for monitoring a signal which is intended for being one of (a) transmitted from the device to a further device connected to the field bus and (b) received by the device from the further device,
• wherein the processing unit is further adapted for determining at least one physical layer parameter of the signal.

A method for monitoring a signal by a device, the device being one of a filling level measuring device, a pressure measuring device and a flow measuring device, the signal being intended for being one of (a) transmitted from the device to a further device connected to the field bus and (b) received by the device from the further device, the method comprising the steps of:

• monitoring the signal;
• and
• determining at least one physical layer parameter of the signal.
