Current Configuration Name.
Name of currently loaded config file. Does not include the
extension. Each 16-bit register contains a single character.
Stamps contain trigger timing information used for synchronizing PLC's actions. PLC can also use this
information to match up data from multiple Gocator sensors. Stamps are updated after each range data
is processed.
