8.2 Ethernet Error Messages
ErrInternetor messages or warnings that are generated when a device is mounted, are stored in
plain language in an ERROR file.
When the control is switched off and on, the contents of this file is deleted.
The entries in this file can be viewed by entering the code number "NET123" and pressing the
soft key "SHOW ERROR".
Structure of an Error Message
A message starts with the program part that detected the error; this element is terminated by a
colon. Then the name of the device to be mounted can follow in <> angle brackets. The software
differentiates between errors (E) and warnings (W). In the event of an error the network cannot
be activated and the device cannot be mounted. When a warning is generated, the network
could be activated or the device mounted, however, inappropriate entry values were corrected.
Errors reported by the link layer:
LL: (W) CONNECTION "error string" UNKNOWN USING DEFAULT 10BASE2
An unknown name was entered for the connection.
10BASE2 (Thin Ethernet) is used.
LL: (E) PROTOCOL "error string" UNKNOWN
