Transducer block
The transducer block contains the parameters required to calibrate the device. These parameters can
also be addressed by using the VU 331 display module. The calibration of the device is described in
Chapter 5.5.5 to Chapter 5.5.7
Operation
The resource block is opened by a click on the resource line.
Parameter changes from the tool are made off-line while the device is operating. The changes are
downloaded by first setting MODE_BLK = OOS then pressing the WRITE CHANGES button. Press
the READ ALL button to check the values stored in the device. Normally operation is resumed as
soon as MODE-BLK is set to AUTO.

Configuration parameters
The transducer block also contains the configuration parameters, which are used to commission and
calibrate the instrument. They are identical to the functions of the operating menu, except for the
service parameters which are not accessible on the bus. Thus, the calibration procedure via the
display module (Chapter 6.4) is equally valid for a calibration via a network configuration tool.
A complete list of the configuration parameters can be found in the "Description of Instrument
Functions", BA 221F/00/en.
