value table to the signal in the database, you can use the relevant symbolic descriptor
instead of a numeric value. You can select this from the signal value table in the
middle column.
Physical dimensions are stored in discrete form in the CAN messages. However, it
may not always be possible to represent the numeric value entered in the Value box
as a discrete value. In such cases, when exiting the line or activating the [OK] button,
the two next possible physical values are displayed in a dialog. Then the entered value
is rounded to the next possible closest value.
Example:
The signal EngineData.RPM is defined as a 16 bit unsigned with an offset of 0
and a factor of 10. If the value to be compared is entered as 1015, the raw
value would have to be 1015/10 = 101.5. Since only discrete values may occur,
either 101 or 102 must be used, which correspond to the physical values 1010
or 1020. It is these two numbers which appear in the dialog.
In spite of discrete memory storage, quantities which have digits after the decimal
point can be valid. In the example above, if a factor of 10.5 is used for calculation
1008 and 1018.5 are recommended as possible values.
4.1.4 Entry of Mode-Dependent Signals
Generally there is a direct, fixed assignment of a message's data segment to a signal.
However, for multiplex messages different signals are transmitted in the data
segments, depending on a mode signal. Only a subset of all possible signals of the
message is defined for a mode value.
In the dialog for inputting signal values, the standard signals and mode-dependent
signals are shown in two separate list boxes for ease of input. Additionally, all those
signals not defined in the active mode are filtered out in the mode-dependent list box.
The Mode signal and the Mode are displayed in the associated Edit boxes. If the
mode value is changed, the list with mode-dependent signals is reconstructed. The
mode signal itself cannot be changed here.
4.1.5 Function Generator for the Transmit List
It is often the case that the user wishes not only to place certain signal values on the
bus, but rather entire signal responses. The generator block has a signal response
generator for this purpose, which you configure with the [Response...] button.
