Diagnostics levels in PROFINET IO

Concept
The IO device sends all error messages that occur to the IO controller. The scope and volume
of diagnostics information varies according to the level of diagnostics data evaluation and the
PROFINET devices you are using.
Diagnostics levels
You can evaluate diagnostics data at different levels. The number and type of channels is
selected, for example, at the diagnostics level 4.
The following figure shows the diagnostics levels with PROFINET IO.
