Slave Diagnostics Byte 3
A layout of Byte 2 is shown below. This byte is mapped to the high-byte of Word D + 1.
This bit is set by the Master Unit if the slave has returned an invalid response to a
Master request message. The slave device will set this bit to 0.
Set by the slave device, this bit indicates that 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.
This bit indicates that the slave device has been parameterized by another mas-
ter. The bit is set by the Master Unit, if the address in byte 4 differs from 255 and
from the Master Unit's own address. The slave device sets this bit to zero.

Byte 2
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 (i.e. using the STOP FINS command). The slave device is allocated to the
Master Unit, but removed from cyclic processing.
