1. Add a 'Sub-Sequence' to the Sequence.
![](/servlet/rtaImage?eid=ka03q000000tIMz&feoid=00N3q00000HUsuI&refid=0EM0Z000000SEEP)
2. Add a 'SequenceCall' to the newly created 'Sub-Sequence' in the Main sequence.
![](/servlet/rtaImage?eid=ka03q000000tIMz&feoid=00N3q00000HUsuI&refid=0EM0Z000000SEEF)
3. Change
Execution Options to
Use New Thread in Step Settings for SequenceCall.
![](/servlet/rtaImage?eid=ka03q000000tIMz&feoid=00N3q00000HUsuI&refid=0EM0Z000000SEE5)
4. In the sub-sequence, call the VI that needs to be shown in an action step.
![](/servlet/rtaImage?eid=ka03q000000tIMz&feoid=00N3q00000HUsuI&refid=0EM0Z000000SEEe)
Note, the VI that is being called must have a '
While Loop' with a '
Stop Button'.5. Set "Show VI Front Panel is Off" as "Show VI Front Panel is On" and then it indicates a green symbol like below.
![](/servlet/rtaImage?eid=ka03q000000tIMz&feoid=00N3q00000HUsuI&refid=0EM0Z000000SEEj)
The test sequence can only be terminated by actuating the 'stop button' on the front panel of the open VI.
