Trigger condition: Trigger on variable
1. Select a trigger parameter from the "Trigger variable" field. The following options are
available:
– Click on the icon
– Enter the name or the parameter number into the input field for the trigger parameter.
Additional specific setting options are shown in accordance with the data type of the selected
trigger variables. If a trigger variable of the FLOAT data type was selected, for example, a drop-
down list, a diagram and an input field for a threshold value appear. The following settings
can be selected in the drop-down list for the "result":
2. Select the required event in the "Event" drop-down list.
Depending on the selected event, additional settings may be required (see input fields to the
right of the curve diagram). Make the specific event settings.
3. In order to record a time period before the trigger event, enter a value greater than "0" in the
input field for the pre-trigger.
4. Enter the recording time under "Recording duration". The maximum possible recording
duration is displayed to the right.
5. Should you wish to set the maximum recording time, activate the option "Use max. recording
duration".
6. Enter a recording cycle under "Cycle" The possible cycle settings depend on the number of
signals.
Trigger condition: Trigger on alarm
1. Select a trigger parameter from the "Trigger variable" field (see "Trigger on variable").
2. In order to record a time period before the trigger event, enter a value greater than 0 in the
input field for the pre-trigger.
3. Enter the recording time under "Recording duration". The maximum possible recording
duration is displayed to the right.

for the trigger parameter and select a parameter.
"Rising signal" The recording starts if the falling value of the trigger reaches or exceeds the
configured value. After activating the trace, at least 2 cycles are required in
order to identify the signal edge.
"Falling signal" The recording starts if the falling value of the trigger reaches or falls below the
configured value. After activating the trace, at least 2 cycles are required in
order to identify the signal edge.
"Within the toler‐ Recording starts as soon as the value of the trigger lies within the configured
ance band" value range.
"Outside the toler‐ Recording starts as soon as the value of the trigger lies outside the configured
ance band" value range.
"= TRUE" Recording starts when the status of the trigger is TRUE.
"= FALSE" Recording starts when the status of the trigger is FALSE.
"= Bit pattern" The recording starts when the value of the trigger coincides with the bit pattern
configured for this event. The individual bit allocation is displayed using a tool‐
tip, which means that the relevant bits can be more easily identified.
Further information
You can find further information on the setting options for the trigger event "
= bit pattern" in the information system of the Startdrive.
