Levelflex M FMP43 with FOUNDATION Fieldbus
1) If MODE_BLK refuses to be changed to AUTO, an error is present. Control all parameters, perform the required changes and try again to change MODE_BLK
to AUTO.

5.5.6 Sensor Block
The Sensor Block contains the parameters required to calibrate the device. These parameters can
also be addressed by using the VU331 display module. The calibration of the device is described in
Chapter 6.
Operation
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. In
order to resume operation, change MODE-BLK to AUTO
Block administration parameters
Parameter Description
MODE_BLK See description in Resource block. The possible operating modes of the Sensor block are:
– AUTO: the block is operating as normal
– OOS: the block is out of service.
TAG_DESC User description of the intended application of the block.
BLOCK_ERROR Shows error status of software and hardware components
– Out-of-Service: the block is in OOS mode
Output values
Parameter Description
PRIMARY_VALUE Main value (level or volume).
SECONDARY_VALUE Measured distance.
Configuration parameters
The Sensor 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", BA245F/00/en.
Methods
The FOUNDATION Fieldbus specification provides for the use of so-called methods to simplify the
operation of the device. A method is an interactive sequence of steps that must be followed in order
to obtain a particular function from the device.
The Levelflex M has got the following methods:
• Basic setup
• Safety settings
• Acknowledge alarm
• Length adjustment
• Linearisation
• Extended calibration
• Output
• System parameters
• Lock TB Manufacturer parameters
