Condition for Start trace
With "Start trace" softkey The recording is started immediately after pressing the "Start
trace" softkey.
If variable The recording is activated after pressing the "Start trace"
softkey when the selected variable clearly satisfies the con‐
dition and the specified value.
The following conditions are offered:
● Positive edge
● Negative edge
● With bit mask
The "Bit mask" softkey is displayed when the "Bit mask" con‐
dition is selected in order to select the desired bits. Irrespec‐
tive of the maximum value (hexadecimal) which is possible
through the bit mask, a "Value" (decimal) can be entered at
which the trace recording starts precisely.
Example:
The trace recording is started when the following bits are set:
Bit 0 = 0; bit 1 = 1; bit 2 = 0; bit 3 = 1
Bit mask = fH Condition Value (decimal)
Variable: CU/
r722/3.3.1
With bit mask
☑ Bit 0
☑ Bit 1
☑ Bit 2
☑ Bit 3

Preprocessing time [s]: The input of a preprocessing time corresponds to the func‐
tional parameter p4722 "Trace trigger delay":
● A positive preprocessing time starts the recording before
the trigger event.
● A negative preprocessing time starts the recording after
the trigger event.
When entering a preprocessing time, the entire duration of
the recording must be taken into account:
● If the preprocessing time is greater than the entire
duration of the recording, the entry is rejected.
● If too large a preprocessing time is entered, the trigger
event may not be recorded.
Data storage on CU
Drive trace rate [μs]: Enter a factor with the "Sampling rates" softkey to set the
effective sampling rate. With a higher sampling rate, the re‐
cording duration is also longer.
Condition for Stop trace
If the time has expired Defines the period which after expiry, the recording is exited.
If the memory is full The recording is terminated when the specified data volume
(KB) is reached.
