9.2.1.1 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
F
Failure. A device error has occurred. The measured value is no longer valid.
C
Function check.
The device is in service mode (e.g., during a simulation).
S
Out of specification. The device is operated outside its technical specification limits (e.g., outside the process
temperature range)
M
Maintenance required. Maintenance is required. The measured value remains valid.
9.2.1.2 Diagnostic behavior
Symbol Meaning
Alarm. Measurement is interrupted. Signal outputs assume the defined alarm condition. A diagnostic message is
generated.
Warning. Measurement is resumed. The signal outputs are not affected. A diagnostic message is generated.
