Operating elements
If two or more diagnostic events are pending simultaneously, only the message of the
diagnostic event with the highest priority is shown.
Other diagnostic events that have occurred can be displayed in the Diagnostics menu:
• Via parameter →  141
• Via submenus →  142
Status signals
The status signals provide information on the state and reliability of the device by
categorizing the cause of the diagnostic information (diagnostic event).
The status signals are categorized according to VDI/VDE 2650 and NAMUR
Recommendation NE 107: F = Failure, C = Function Check, S = Out of Specification, M
= Maintenance Required
Symbol Meaning
Failure
A device error has occurred. The measured value is no longer valid.
Function check
The device is in service mode (e.g. during a simulation).
Out of specification
The device is being operated:
• Outside its technical specification limits (e.g. outside the process temperature range)
• Outside of the configuration carried out by the user (e.g. maximum flow in parameter
20 mA value)
Maintenance required
Maintenance is required. The measured value remains valid.
