5.7 Measuring point information
The following information about the measuring point can be read:
All blocks
Resource block
Transducer block
Analog input block
Parameter
Significance
PV
The input value of the analog input block or a value associated with it (%)
FIELD_VAL
Output of transducer block in % of set range.
OUT
The value output by the analog input block
XD_SCALE...
The scaling values and engineering units for FIELD_VAL and PV
These are always 0% and 100% for L_TYPE = DIRECT.
For L_TYPE = INDIRECT they should be correspond to the range values set
for the transducer block output value, e.g. during a linearization.
OUT_SCALE
The scaling values for the OUT value.
These are always 0% and 100% for L_TYPE = DIRECT.
For L_TYPE = INDIRECT they can be adjusted the desired OUT range.
L_TYPE
Type of linearisation: must always be set to DIRECT or INDIRECT
HI_HI_ALM
Flags status of upper alarm limit
HI_ALM
Flags status of upper warning limit
LO_ALM
Flags status of lower warning limit
LO_LO_ALM
Flags status of lower alarm limit
Parameter
Significance
WRITE_LOCK
Indicates position of write protection DIP-switch WP
Parameter
Significance
MODE_BLK
Indicates current operating mode of block
Parameter
Significance
PRIMARY_VALUE
Primary value output by transducer block, here it is pressure
SECONDARY_VALUE
Secondary value output by transducer block, here it is temperature
Measured Value
Pressure displayed by the device after calibration and any
scaling/linearization.
Sensor pressure
Actual sensor pressure (Unit selectable with "Select Pressure Unit")
Lower Sensor Limit
Lower range-limit of sensor (Unit selectable with "Select Pressure Unit")
Upper Sensor Limit
Upper range-limit of sensor (Unit selectable with "Select Pressure Unit")
Lower Range Value
Lower range-value – zero (affects bargraph)
Upper Range Value
Upper range-value – span (affects bargraph)
Int. Counter high
Counter for pressure values above the upper range-limit, max. value = 255,
Options: # – no action, clear – counter is reset to "0"
Sensor Temperature
Actual sensor temperature (Unit selectable with "Select Temperature Unit")
Unbiased Pressure
Current pressure value without bias correction
Biased Pressure
Current pressure value with bias correction
Transducer_sw_vers
Sofware version of the device
Diagnostic Code
Code with associated message of current device alarm
Last Diagnostic Code
Code with associated message of previous device alarm
