Slave Diagnostics Byte 4: Master PROFIBUS Address
This byte contains the PROFIBUS address of the Master Unit, which parameterized the slave. If the slave is not
parameterized correctly, the byte contains FF (Hex) or 255 (Decimal).

Byte 2
This bit is set by the Unit and indicates that it needs to be (re-)parameterized.
The Unit 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 Unit. The Master Unit will repeatedly
request diagnostics data. As long as this bit is set, Data_Exchange with the Mas-
ter Unit is not being performed.
This bit is reserved and always set to 1 by the Unit.
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 Unit 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 Unit 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 Unit has been disabled (i.e.
using the STOP FINS command). The Unit is allocated to the Master Unit, but
removed from cyclic processing.

Byte 3
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 Unit 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 diag-
nostic buffer.
