Configurable data blocks
Data Blocks is used to transfer data from the
instrument to the master. Up to 12 data
blocks can be used. Each block consists of
16 bytes. The data blocks have fixed
positions in memory, see list below.
Last byte is no. 223. A total of 224 bytes
data can be mapped from the instrument to
the master. Of the maximum 224 bytes are
32 bytes the mandatory base block.
Type of data blocks
•
Gross Weight data, floating point or integer format
•
Net Weight data, floating point or integer format
•
Displayed Weight data, floating point or integer format
•
Flow Rate data, floating point or integer format
•
Input Signal (transducer mV/V) data, floating point or integer format
•
Level status, floating point format
•
Setpoint status, floating point format
•
Input status, floating point format
•
Output status, floating point format
•
Input and output status, integer format
•
Level and setpoint status, integer format
•
Analog output value 1 to 4, floating point format
•
Analog output value 1 and 2, integer format
•
Analog output value 3 and 4, integer format
The offset in the left column, in the following descriptions of the data block types,
is the starting byte number (see table above) for the actual data block number.
The Weight data blocks (floating-point and integer formats) below are a common
description of the five different types that can be selected: Gross Weight, Net Weight,
Disp. Weight, Flow Rate and Input Signal.
See chapter ‘Communication – Modbus protocol’ for a description of the contents
of the different data blocks and the integer and floating-point data formats.
