14.1.3 Division of the aloha data into individual data fields
#aloha up
BatVoltage s16 title="Battery Voltage" decpl=2 units="V" vscale=0.001
InputVoltage s16 title="USB Voltage" decpl=2 units="V" vscale=0.001
The first line in the example above specifies the container to be used for the aloha data:
#aloha:
The measurement data should be stored in the aloha data container.
up:
The data is only transmitted from the device to the server.
Note:
After specifying the direction of transmission other attributes (e.g. "title") could be added.
The second line in the example above describes the first measurement value in the aloha data container
used:
BatVoltage:
"BatVoltage" should be used as the name for the measurement value.
s16:
The data type used for the measurement value should be a 16-bit signed integer.
title:
Name of the measurement value that is displayed on the server
decpl:
Number of decimal places that should be displayed
units:
Unit of the measurement value that is displayed on the server
vscale:
Virtual scaling of the value (see "Attributes of the field definition" on page 238).
Note:
Name and data type must always be specified. Attributes are optional. Further attributes can
also be added.
The third line in the example above describes the second measurement value in the aloha data container
used.
14.1.4 Attributes of the field definition
title
Alpha-numeric. Title of the field. This title is then used in all of the reports, graphics, etc. for this channel.
The length of the title should not exceed 16 characters if possible, otherwise this can cause display
problems on the interface.
units
Alpha-numeric. Units of a value.
The length of the units should not exceed eight characters if possible, otherwise this can cause display
problems on the interface.
bitmask
Hexadecimal, without leading "0x". Bit mask to mask the actual bits to be used out of the data block,
hexadecimal. The extracted value is aligned to the LSB following the masking process.
Example: An u16 field is generated out of two bytes with the 0xF3A7 content. 0FF0 is specified as the
bit mask. The bits are extracted and aligned with the LSB. The subsequent HEX value is therefore
0x3A (=58 decimal).
