Device status symbols

The device status is displayed on the display with the help of symbols. Alarms are displayed on
the display in the measurement view as symbol in the bottom line of the display. If multiple
diagnostic states are pending at the same time, the symbol for the most critical status is
displayed. The table below shows the possible causes for the device status and measures for the
user or service. The order of the symbols in the table corresponds to the priority of the device
status, starting with the most critical message.

Meaning
Priority * Priority *
1 Cause: Output signal invalid due to fault in the field device or in the pe‐
ripherals.
Measure: Maintenance is required immediately.
2 Cause: Output signal temporarily invalid (e.g. frozen) due to work being
performed on the device.
Measure: Manual mode over HMI or disable the engineering system.
3 Cause: Deviations from permissible ambient or process conditions detected
by the device (by means of self-monitoring or based on warnings/errors in
the device) indicate that the measured value is unreliable or that deviations
from the set value in the actuators are most likely greater than anticipated
under normal operating conditions.
Process or ambient conditions can damage the device or result in unreliable
results.
4 Cause: The output signal is still valid but the wear reserve is coming to an
end and/or functional restrictions will occur soon.
Measure:Maintenance is recommend as soon as possible.
