17.2 Measured value in extended float format
(0082
hex
: Measured Value Float)
You can read the IN process data in IBIL or S7-compatible
format with the 0025
hex
object.
The 0082
hex
object is also available.
This object provides the measured value in the highest inter-
nal accuracy of the terminal in the float format.
Measured value channel 1 ... channel 4
Structure of the float format according to IEEE 754 in the bit
representation:
Some example values for conversion from floating point to
hexadecimal representation:
Extended Float Format
Extended Float Format is a specially defined format. It con-
sists of the measured value in float format, a status, and a
unit.
Status is necessary because the float format defines no pat-
terns providing information on the status of the numerical
value.
The status corresponds to the LSB of the diagnostic code in
IBIL format (e.g., overrange: status = 01, diagnostic code =
8001
hex
). If status = 0, the measured value is valid.

17.3 Minimum process data value
(0083
hex
: PD Min)
Object 0083
hex
can be used to read the minimum process
data values.
The values are initialized after each parameterization. The
highest value is assigned for the minimum process data
value.
PD Min = 7FFF 7FFF 7FFF 7FFF 7FFF
hex
On every analog conversion, the PD Min value is compared
with the current measured values and overwritten if neces-
sary.
17.4 Maximum process data value
(0084
hex
: PD Max)
Object 0084
hex
can be used to read the maximum process
data values.
The values are initialized after each parameterization. The
lowest value is assigned for the maximum process data
value.
PD Max = 8000 8000 8000 8000 8000
hex
On every analog conversion, the PDMax value is compared
with the current measured values and overwritten if neces-
sary.

17.5 Local adjust values (008F
hex
)
This object supports a channel-specific path calibration function for maximum accuracy. This means, forexample, that you
can finely tune the tolerances by means of the TC connecting cables and the sensors.
The calibration data is permanently stored on the module.
The object contains the temperature offset of the cold junction with reference to each channel in IBIL format with a resolution
of0.1°C.
Example:
Channel1 is measuring+2.0°C too high.
A negative offset of-2.0°C is required to correct this error.
In IBIL format, -2°C corresponds to a value of -20
dec
= FFEC
hex
.
17.6 Channel Scout (0090
hex
)
This object is used to quickly find a channel.
The function is terminated automatically after five minutes if
you do not deactivate the Channel Scout processes. The
flashing overrides all diagnostic messages of the selected
channel. When a channel is parameterized, the Channel
Scout function is aborted.
