System error messages

Serious system errors are always recognized by the measuring device as a "fault message" and
shown as a lightning flash symbol ($) on the display! Fault messages immediately affect the inputs
and outputs. Simulations and positive zero return, on the other hand, are classed and displayed as
"Notice messages".
Caution!
In the event of a serious fault, a flowmeter might have to be returned to the manufacturer for repair.
Important procedures must be carried out before you return a flowmeter to Endress+Hauser.

Always enclose a duly completed "Declaration of contamination" form. You will find a preprinted
blank of this form at the back of this manual.
Note!
• The error types listed in the following correspond to the factory settings.

9.2.1 Displaying the device status on PROFIBUS DP/PA
Display in the operating program (acyclic data transmission)
The device status can be queried using an operating program (e.g. FieldCare):
Function block SUPERVISION → SYSTEM → OPERATION → ACTUAL SYSTEM CONDITION
Display in the PROFIBUS master system (cyclic data transmission)
If the AI or TOTAL modules are configured for cyclic data transmission, the device status is coded
in accordance with PROFIBUS Profile Specification 3.0 and transmitted with the measured value to
the PROFIBUS master by means of the quality byte (byte 5). The quality byte is split into the "quality
status", "quality substatus" and "limits" segments.

Fig. 68: Structure of the quality byte
The content of the quality byte depends on the failsafe mode error behavior configured in the
corresponding Analog Input function block or totalizer function block. Depending on which failsafe
mode has been set in the FAILSAFE_TYPE function, the following status information is transmitted
to the PROFIBUS master via the quality byte:
• For the selection FAILSAFE_TYPE → FSAFE VALUE :
