If you require more than two settings for your measurements, you can either save the individual
settings in the project or export them in *.clg format, and load or import them, if necessary.
You can record individual bits of a parameter (e.g. r0722. 1) by allocating the relevant bit using
"bit track" (
Using the mathematical function (
between the speed setpoint and the speed actual value.
The device trace shows "individual bits" or "mathematical functions" as signal No. 9.
Recording cycle and duration
The device trace records data in a CU-dependent basic cycle clock. The maximum recording
duration depends on the number of recorded signals and the trace clock cycle.
Proceed as follows to extend the recording duration:
1. Multiply the trace clock cycle by an integral number.
2. Accept the displayed maximum duration using
Alternatively, you can also specify the measurement period and then calculate the trace clock
cycle of STARTER using
Trigger (condition to start the device trace)
The device trace starts as soon as you press the
Using the button , you can define another trigger to start the device trace.
The pretrigger defines the time in which the signals are traced before the trigger condition. As
a consequence, the trigger condition traces itself.
Example of a bit pattern as trigger:
You must define the pattern and value of a bit parameter for the trigger. To do so, proceed as
follows:
Using , select "Trigger to variable - bit pattern"
