1. If this is the first calculated signal to be defined, you can directly
start with step 2. If you have already defined a calculated signal,
click .
By default, the name of the new calculated signal is set to "Cal-
culatedSignal". If this name is already in use, it is extended by an
increasing number.
2. In the Name field, you can enter another name instead of the
default name.
Note
Valid characters are a-z, A-Z, 0-9, underscore, point, and square
brackets. Square brackets must always occur in pairs. Other
characters or blank space are not allowed.
3. Optionally, you can enter a unit in the Unit field.
4. Drag and drop one or more input signals into the Formula Defin-
ition field.
Note that enumeration signals can be used as input signals only
in combination with the following functions:
Raw() function for mathematical calculations using the
decimal implementation value
ToString() function for comparing the strings of different
enumeration signals.
For each input signal, the file identifier and the short name of the
signal are displayed. If several signals with the same short name
exist, information about the device and/or the raster is addi-
tionally displayed to distinguish the signals.
If an input signal contains an error or warning, a corresponding
icon is displayed in front of the file identifier. Note that you can
save a calculated signal even if an input signal contains an error.
5. Connect the signals with mathematical operators.
You can drag a mathematical operator from the Toolbox field
into the Formula Definition field. The Help field displays addi-
tional information about the meaning and usage of the operator.
Tip: To quickly navigate through the formula, use the keyboard
buttons.
6. Open the Output Options and define the following parameters:
