M_START

Start of a measurement
Start

Note: The Modbus master must set the register back to 0 after the measurement has started.

The started measurement is indicated as “Busy” in the M_STATUS register

40046

M_DISTANCE

Actual measured distance, in mm
Note: After the unit has finished the measurement, the M_STATUS register states “Ready,

measurement valid” (the Modbus master must read the M_STATUS register).
Then the data on the register M_DISTANCE is valid.

40055

M_VOLUME

Actual measured volume (considering the programmed cone height), in ‰

See note on register M_DISTANCE

40052

M_INHIBIT

Block command (allows to block the unit, so that no measurement can be started)

No block

Block

The unit will remain blocked as long as the register has the value “Block”.

Note: Unit states the blocked status through the M_ STATUS register.

40045

M_STATUS

States the functional status of the unit
Blocked

Ready, measurement not valid

Ready, measurement valid

Busy

Failure present

Temporary not ready
