Description
Callendar Van Dusen A
(CVD_COEFF_A)
OOS
Sensor linearization according to the Callendar Van Dusen
method.
The CVD_COEFF_XX parameters are used to
calculate the sensor characteristic curve if "RTD-
Callendar Van Dusen" is set in the SENSOR_TYPE
parameter. Both Transducer Blocks make a wizard
available for configuring the parameters according to
the "Callendar Van Dusen method".
Callendar Van Dusen B
(CVD_COEFF_B)
OOS
Callendar Van Dusen C
(CVD_COEFF_C)
OOS
Callendar Van Dusen R0
(CVD_COEFF_R0)
OOS
Callendar Van Dusen
Measuring Range Maximum
(CVD_COEFF_MAX)
OOS
Upper calculation limit for Callendar Van Dusen
linearization.
Callendar Van Dusen
Measuring Range Minimum
(CVD_COEFF_MIN)
OOS
Lower calculation limit for Callendar Van Dusen
linearization.
Polynom Coeff. A
(POLY_COEFF_A)
OOS
Sensor linearization of copper/nickel resistance
thermometers (RTD).
The POLY_COEFF_XX parameters are used to
calculate the sensor characteristic curve if "RTD -
polynomial nickel" or "RTD - polynomial copper" is set
in the SENSOR_TYPE parameter. Both Transducer
Blocks make a wizard available (Sensor Polynomial)
for configuring the parameters according to the
"Polynomial method".
Polynom Coeff. B
(POLY_COEFF_B)
OOS
Polynom Coeff. C
(POLY_COEFF_C)
OOS
Polynom Coeff. R0
(POLY_COEFF_R0)
OOS
Polynom (Nickel/ Copper)
Measuring Range Maximum
(POLY_COEFF_ MAX)
OOS
Upper calculation limit for the RTD polynomial (nickel/
copper) linearization.
Polynom (Nickel/ Copper)
Measuring Range Minimum
(POLY_COEFF_ MIN)
OOS
Lower calculation limit for the RTD polynomial (nickel/
copper) linearization.
Device temperature
(DEVTEMP_ VALUE)
Dynamic / read
only
Internal device temperature measurement:
• VALUE
• STATUS
Reference junction type
(RJ_TYPE)
OOS
Configuration of reference junction measurement for
temperature compensation:
• NO_REFERENCE:
No temperature compensation is used.
• INTERNAL:
The internal reference junction temperature is used for
temperature compensation.
• EXTERNAL:
RJ_EXTERNAL_VALUE is used for temperature
compensation.
Device temperature value unit
(DEVTEMP_UNIT)
Read only
Unit of the internal device temperature. This always
corresponds to the unit set in SENSOR_RANGE →
UNITS_INDEX.
Reference junction external
value (RJ_EXTERNAL_VALUE)
OOS
Value for temperature compensation (see the RJ_TYPE
parameter).
Device temperature max.
indicator (DEVTEMP_
MAX_INDICATOR)
AUTO - OOS
Max. indicator for the internal device temperature, is
stored in the non-volatile memory in intervals of 10
minutes.
Device temperature min.
indicator (DEVTEMP_
MIN_INDICATOR)
AUTO - OOS
Min. indicator for the internal device temperature, is
stored in the non-volatile memory in intervals of 10
minutes.
