Connection Errors
In the event of an error connecting to a WBM page, "wbm error" is displayed
instead of any valid data.
Connection errors may occur due to the following factors:
•
The physical ETHERNET connection to the device has been interrupted. In
this case, a PROFINET IO diagnostic message should appear. There may be
a failure of the entire device.
•
The IP connection has been interrupted. Causes may include:
-
Reparameterization of the IP address of the device
-
Failure of the PC network card
•
The maximum number of connections (3) to the WBM page has been
exceeded

In addition to diagnostics via the WBM (see previous chapter "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 chapter "LED Signaling")
•
PROFINET IO diagnostics
by reading the diagnostic data sets (records)
(see chapter "PROFINET IO Diagnostics")
