Length
Defines the size of the mapped numeric variable or constant in bits. If a string is mapped
this defines the length of the string in bytes.
Mapped length can be shorter than the length defined for the variable but not longer. By
default the variable length is used.
Is Constant
Enable this checkbox to define a constant. Depending on the mask constants can be
used to fill gaps or recognize multiplexers in receive mappings. In transmit mappings
constants are required for every part of the message not filled with a variable.
Uncheck this property to map a variable.
Constant Value
Although appearance does not change this property is only valid and editable for
constants i.e. lines where "Is Constant" property is set.
If valid this defines the numeric value of the constant. Please note that constants are
always expected to be numeric - there is no option to define string constants.
Group
Variable group containing the variable to be mapped. Does not apply to constants.
Variable
The variable to be mapped.
Mask
Variable or constant are bitwise ANDed with mask before they are applied.
See receive condition on how this can be used to receive multiplexed mappings.
See section mapping calculations for details about how this property applies to
receive and transmit mappings.
Mask is not used for String variables.
Offset1
Offset1 is a floating point value applied to the received value after mask and shift factor
but before scale and offset 2.
See section mapping calculations for details about how this property applies to
receive and transmit mappings.
Offset 1 is not used for String variables.
Values can be entered in decimal form or in scientific notation / floating-point
representation.
Shift X Bits
Shift received value to the right by as many bits as defined here. Negative values shift to
the left.
This value is applied after the mask but before offset and scale.
See section mapping calculations for details about how this property applies to
receive and transmit mappings.
Shift is not used for String variables.
