Errors can occur during startup of the VersaPoint station as well as during
operation. There are basically two ways of detecting errors. One way errors can be
detected is by using local diagnostics with the help of the Profibus NIU LEDs and
those on the VersaPoint I/O modules. Alternatively, all types of errors can be sent
from the Profibus NIU to the Profibus master via the Profibus diagnostic telegram
so that errors can also be diagnosed and corrected using software in the
controller.
