Action 7
Some switches are buffering data that needs to be present. This buffering time
might be too long. Try to switch to a simple hub or to decrease this buffer time.
Make sure that you have the newest software running on the hub/switch. Make
sure that there are no infinite loops in the RAPID code because it will affect the
robot network communication .
Action 8
Debug the implementation of the external sensor.
Action 9
For external sensors there might be a small constant delay between the strobe
pulses and the recording of time stamps (For example, if the trigger signal is cross
connected with the strobe). Modify the Position Source parameter Synchronization
tune to modify all time stamps sent to PickMaster with a constant time value.
