The Concurrent Teaching Station (CTS) can be used off-line for creation and modification of inspection programs, and in-line for program tuning during inspection without stopping or slowing down the production line. Working in this way the machine is never a bottleneck, even if some tuning is being made or not during inspection mode. The optimization of the programs on the off-line programming station during inspection ensures implementation time and the uploading of programs from the inspection results is as fast as possible. Recommended feature on all RNS machines for both in line and desktop models.
