In addition to diagnostics via the WBM (see previous section “Web-based
Management”), there are two other options for diagnostics for the fieldbus
coupler.
The listed diagnostic options are described below:
•
LED signaling
for onsite diagnostics
(see section “LED Signaling”)
•
PROFINET IO diagnostics
by reading the diagnostic data sets (records)
(see section “PROFINET IO Diagnostics”)

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