Submenu "System information"
In addition to the system information described from Page 63 onwards, the following parameter is
also available in the Expert setup.
Submenu "Measured values"
The menu is only visible in the online mode!
All the measured values with their related status information are displayed in the "Measured values"
Expert menu. Furthermore, the unscaled, unlinearized measured value of the sensor input in ques-
tion can be read out by means of the "Raw value" parameter. For example, in the case of a Pt100
the actual Ohm value that can be used to calibrate and calculate Callendar-Van Dusen coefficients
is displayed.

Description
PV value n
read
Displays the primary output value of the Transducer
Block.
! Note!
The "PV value" can be made available to an AI Block for
further processing.
The quality of the measured value is displayed with the
"Qualtity" and "Status" parameters.
PV value n - Quality read Displays the quality (measured value status) for the PV
value.
For list of options,Page 80
PV value n - Status read Displays the limit (measured value status) for the PV
value.
0x00 - OK
0x01 - Limit underflow
0x02 - Limit overflow
0x03 - Value constant
Process temperature
n
read Displays the measured value of sensor n.
Process temperature
n - Quality
read Displays the quality (measured value status) of the process
temperature for sensor n.
For value, see "PV value n - Quality"
Process temperature
n - Status
read Displays the limit (measured value status) of the process
temperature for sensor n.
For value, see "PV value n - Status"
RJ temperature n read Displays the internal reference temperature.
