Diagnostics
Status 2
Byte 1, Status 2
Bit
Meaning
0
Prm_req
The DP Device always sets the bit to 1 if it needs to be reconfigured and
parameterized. The bit remains set until parameterizing is done.
1
Stat_Diag
(statistic diagnostic)
The Device sets the bit to 1 if for example it can not send valid data. In this case the
DP Master retrieves diagnostic data until the bit is reset to 0.
2
Fixed at 1
3
WD_On
Monitoring activated/deactivated (Watchdog on).
4
Freeze_Mode
The Device sets the bit to 1 if it has received the Freeze command.
5
Sync_Mode
The Device sets the bit to 1 if it has received the Sync command
6
Not_Present
The DP Device always sets the bit to 0. The DP Master sets it to 1 for the DP Device
which are not contained in the Master parameter set.
7
Deactivated
The DP-Device always sets the bit to 0. The DP-Master sets it to 1 if the DP-Device
is removed from the Master parameter set.
Status 3
Byte 2, Status 3
Bit
Meaning
0 ... 6 reserved
7
Ext_Diag_Overflow
If this bit is set, there is more diagnostics information than indicated in
Ext_Diag
_
Data.
For example the DP Device sets the bit to 1 if there is more channel-specific
diagnostics information than the DP Device can enter in its send buffer.
A DP Master sets the bit to 1 if the DP Device sends more diagnostics information
than the Master can hold in its diagnostics buffer.
Address
Byte 3, Address of the Master
Bit
Meaning
0 ... 7
Master_Add
After parameterizing the address of the DP Master which has parameterized the DP
Device is entered. If the DP Device has not be parameterized by a Master, it sets
address FFhex.
Ident_Number-
_High_Byte
Byte 4, Ident High
Bit

0 ... 7 BNI PBS-507-.....: 0Chex
Ident_Number-
_Low_Byte
Byte 5, Ident Low
Bit
Meaning
0 ... 7 BNI PBS 506-...: 65hex
0 ... 7 BNI PBS 507-...: 64hex
