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:
-
-
•
The maximum number of connections (3) to the WBM page has been
exceeded
