Name
This bit is set by the slave device and indicates that it needs to be (re-)aparame-
terized. The slave device is not in Data_Exchange with the Master Unit. The bit
remains on as long as it has not been parameterized successfully.
This bit indicates static diagnostics at the slave device. The Master Unit will
repeatedly request diagnostics data. As long as this bit is set, Data_Exchange
with the Master Unit is not being performed.
This bit is reserved and always set to 1 by the slave device.
If the watchdog has been enabled at the slave device (through the appropriate
setting in the parameterization message) this bit will be set.
If the slave device has been set to the Freeze mode, using the global command,
this bit will be set to on. The bit will be set to off, if an Unfreeze command has
been received.
If the slave device has been set to the Sync mode, using the global command,
this bit will be set to on. The bit will be set to off, if an Unsync command has been
received.
This bit is reserved.
This bit is set by the Master Unit, indicating that the slave device has been dis-
abled. The slave device is allocated to the Master Unit, but removed from cyclic
processing.

Name
These bits are reserved and always set to 0 by the slave device.
If set, this bit indicates that there exists more diagnostic information than speci-
fied in Ext_Diag_Data. This bit will, for example, be set if the slave device has
more diagnostics available than it can enter in its send buffer. This bit will also be
set if the Master Unit receives more diagnostic information than it can enter in its
diagnostic buffer.
