ETAS 4 Calculated Signals
No. Description
List of all calculated signals
As soon as you have created a calculated signal, it is displayed in
this area. From here, you can perform the following actions:
l To use a calculated signal, drag and drop it into an instrument
of your configuration.
l Select a calculated signal in the list to edit, duplicate, or delete
it. For more information, see " Managing Calculated Signals"
on page55.
Entry fields to define or edit a calculated signal
To define a calculated signal, drag and drop any input signal from
the Variable Explorer or an instrument or an existing calculated
signal into the formula definition field. To complete the formula,
enter mathematical operators via the keyboard. For more inform-
ation, see "Defining Calculated Signals" below.
List of all mathematical operators
When defining a calculated signal, you can select a mathematical
operator in this list and move it into the formula definition field on
the right side of the editor. Alternatively, you can type the desired
operation name or symbol directly into the formula definition field.
More information about the mathematical operators
When you select a mathematical operator in the list above, this
field displays additional information about the meaning and usage
of the operator.
The same detailed information is shown in the Formula Definition
field, when hovering in edit mode with the mouse onto the func-
tion name.
Note
Calculated signals imported from MDA V7 may behave slightly differently in
MDAV8. For more information, see "Import Calculated Signals from XDA
Files:Differences between MDA V7 and MDA V8 " on page125.
