3-3-2 Diagnostic User Interface
The Extended Diagnostic tab contains any extended diagnostics reported by the slave device. The fig-
ure below shows an example of Extended diagnostics.
The first row of the Extended diagnostics window contains the raw data as received from the slave
device. Depending on the GSD file, it may provide text strings for each Extended diagnostics events
entry, i.e. if the event occurs and the diagnostics information is received by the DTM it can display a text
string in stead of only the raw bytes.
If the strings are not supported, the user must determine the event from the raw data bytes.
Invalid slave
response
The slave has returned an invalid response to a Master request message.
Function Not sup-
ported
The Master Unit has sent a message to the slave device, which is not supported by the device.
Extended diagnostics The diagnostics message returned by the slave device contains extended diagnostics, i.e. it contains
more than the mandatory 6 bytes.
Configuration fault The last received configuration data from the Master Unit have been rejected. The configuration data
in the slave device differ from the configuration sent by the Master Unit.
Station not ready The slave device is not yet ready for data transfer (the parameters data and the configuration data
have been accepted).
Station not existent The slave does not respond to any of the request messages sent by the master. If set the diagnostic
bits contains the state of the last diagnostic message or the initial value.
Slave deactivated When set to TRUE, it indicates that the slave device has been disabled. The slave device is allocated
to the Master Unit, but removed from cyclic processing.
Sync mode When set to TRUE, the slave device has been set to the Sync mode, using the global command.
Freeze mode When set to TRUE, the slave device has been set to the Freeze mode, using the global command.
Watchdog on The watchdog has been enabled at the slave device (through the appropriate setting in the parameter-
ization message).
Slave device Indicates that the device is a slave device.
Static diagnostics When set, the slave device reports static diagnostics, i.e. the error event is serious enough that the
diagnostics is continuously reported. No data exchange will be performed.
Re-parameterization
requested
When set, the slave indicates that it requires a new parameter setting. The slave device is not in Data
Exchange with the Master Unit. The indicator remains ON as long as the slave device has not been
parameterized successfully.
Extended diagnos-
tics overflow
The slave device has more diagnostics to report than it can fit into its transmission buffer. Diagnostics
information is being lost.
