Device status (structure of the second byte)

If a communication error is indicated in the first byte (bit 7 = "1"), the second byte described here has no
significance (always 0).
In the other case, it contains the status of the field device in full, i.e. independent of commands.
The individual bits have the following meaning:
Bit Description
7 Error function of the field
device
(malfunction)
6 Configuration changed
(Configuration changed)
5 Start-up sequence is running The power supply has been con-
4 Extended device status
available
3 Analogue output current
fixed (primary variable)
2 Analogue output current has
reached its limit (primary
variable)
1 Variables (not the primary
one) outside the range
0 Primary variable outside the
range
Subject to reasonable modifications due to technical advances.

Description
Here (137): SCAN value has not been chan-
ged, since it is identical.
The device is executing a function, which
cannot be interrupted by this command.
cannot be executed.
This error message is also output if an error
occurs that cannot be accurately specified
by the device.
Parameter not in the permissible range.
Hardware fault. The extended
device status may provide further
information (see section 5.4).
A write command has been execu-
ted.
nected or a reset has been activa-
ted. Transient data are reset to the
preset values.
Further status messages are
available and can be called up; see
section 5.4.
The primary variable is fixed at the
requested value and no longer fol-
lows the process.
The primary variable lies outside its
limit value and therefore no longer
corresponds to the process value.
The values detected by the sensor
(not for the primary variable) lie out-
side the operating range. The
extended device status may yield
additional information (see section
5.4).
The measured value detected by
the sensor lies outside the opera-
ting range.
