11.9.1 Editing logic analyzer data
In order to capture trace data, the user must enter the variables or expressions to be
analyzed, the trigger type and conditions as well as the time based to be used to
display the captured values.
To edit this data, select the graphic area of the logic analyzer and press the "Edit view"
softkey to place the cursor on the data editing area.
Definition of variables
Up to 8 PLC variables or expressions may be defined to obtain their trace. The
definition of the expression cannot exceed 80 characters.
When modifying a variable, if there was already a trace of that expression, the trace
will be deleted when validating the new edition.
Trigger condition
A trigger condition is the one used to capture data and may be defined with a PLC
variable or expression. The definition of the expression cannot exceed 80 characters.
If the trigger condition is modified after a data capture, all the traces will be deleted
when validating the new condition.
Trigger type
It sets whether the data is to be captured "before", "after" or "before and after" the
selected trigger condition is met.
Time base
The operator may use this parameter to assign the timeframe to each vertical division.
The size of these divisions, therefore the resolution of these signals will be
determined by this time base. Consequently, the smaller the time base, the greater
the signal resolution.
By default The data capture starts and ends when the operator selects the
option to execute and stop the trace.
Before The data capture starts when the trigger condition is met and ends
when the operator selects the option to stop the trace.
Once the trace has been executed, the trigger signal will be shown
at the beginning of the trace.
After The data capture starts when the operator selects the option to
execute the trace and ends when the trigger condition is met.
Once the trace has been executed, the trigger signal will appear
at the end of the trace.
In the middle The data capture starts and ends when the operator selects the
option to execute and stop the trace.
Once the trace has been executed, the trigger signal will be shown
at the center of the trace.
