Generic Slave Device DTM
Section 2-5
The LED indicators are listed in the table below.
Extended Diagnostics
Tab
The Extended Diagnostic tab contains any extended diagnostics reported by
the slave device. The figure below shows an example of Extended diagnos-
tics.
Name
Description
Master lock
The slave device has been parameterized by another master.
Parameter fault
The last received parameter data from the Master Unit have been rejected. The parameter
data in the slave device differ from the parameter sent by the Master Unit.
Invalid slave response
The slave has returned an invalid response to a Master request message.
Function Not supported
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 configura-
tion 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 ON, it indicates that the slave device has been disabled (i.e. using the STOP
FINS command). The slave device is allocated to the Master Unit, but removed from cyclic
processing.
Sync mode
When set to ON, the slave device has been set to the Sync mode, using the global com-
mand.
Freeze mode
When set to ON, the slave device has been set to the Freeze mode, using the global com-
mand.
Watchdog on
The watchdog has been enabled at the slave device (through the appropriate setting in the
parameterization 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 diagnostics
overflow
The slave device has more diagnostics to report than it can fit into its transmission buffer.
Diagnostics information is being lost.
