LED Signaling

For on-site diagnostics, the fieldbus controller has several LEDs that indicate the
operational status of the fieldbus controller or the entire node (see following
figure).

The diagnostics displays and their significance are explained in detail in the
following section.
The LEDs are assigned in groups to the various diagnostics areas:
