4.31.7.8.8.3 Measured value – Unweighted
Name:
Measurand01 to Measurand04
When using the AsIoAcc library, the unweighted measurement can be accessed via this register. This refers to a
measured value that is within the valid measurement range and has not yet been compared with the user-defined
limits.
Data type
Value
DINT
-2,147,483,648 to 2,147,483,647
Information:
If no user-defined limits are configured, the value of this register does not differ from the temperature
or resistance value.
4.31.7.8.8.4 Cycle counter
Name:
IOCycleCounter01 to IOCycleCounter04
This register is used to provide a continuous counter for the application that is incremented each time a temperature
value is read.
Data type
Value
USINT
0 to 32767 [A/D conversions]
UINT
0 to 65535 [A/D conversions]
4.31.7.8.8.5 Sampling time
Name:
Sampletime01 to Sampletime04
This register is used to provide the application the net time until the temperature will be evaluated.
Data type
Value
INT
-32,768 to 32,767 [µs]
DINT
-2,147,483,648 to 2,147,483,647 [µs]
Information:
The SDC library requires a 16-bit value for the sampling time. It is therefore also prepared as a 16-
bit value.
4.31.7.8.8.6 Status messages
Name:
Status01 to Status04
The register bits are set if an error has been diagnosed and the error remains longer than the delay configured
in the "ErrorDelay0x" register.
Data type
Value
USINT
See bit structure.
