The following tables show the meaning of the LED indicators for communica-
tion via PROFINET.

The
NS
LED (network status) is used to indicate network statuses.

The

Reversible vs. non-reversible error
Reversible errors can be resolved by a reset or by power cycling the supply
voltage (turning it off and then back on).
In contrast, fatal errors can only be reset by power cycling the supply voltage
or by changing the hardware configuration while the supply voltage is off.
