Diagnostics
Menu
DiagnosticsM0022
can be used to check the different states of the Profibus
DP interface.
The <Information on Profibus DP 1> tables shows the menus for the 1st DP interface.
In case a second, redundant DP interface is installed, this table may be used as well.
In the menu,
DP2
is displayed instead of
DP1
.

Value and description
Indication in display
Bus address (slave address)
DP1 slave address M0547
Baud rate
DP1 baud rate M0099
Watchdog status
DP1 watchdog status M0411
The Profibus DP interface searches a baud rate. If no baud rate was
found:
●
Connect bus cables.
●
Check bus cables.
●
Switch on DP master.
Baud search
The detected baud rate is monitored. The DP watchdog within the master
is not activated. In this case, the failure function is not available.
Baud control
The DP communication is monitored, the DP watchdog within the master
is activated. Therefore, the failure function is also available.
DP control
Profibus status
DP1 Profibus status M0554
The Profibus DP interface is waiting for correct parameter data.
Wait Prm
The Profibus DP interface is waiting for correct configuration data.
Wait Cfg
The Profibus DP interface is currently exchanging data with the master.
Data Ex
Global Control Clear Status
DP1 GC clear M0556
GC Clear inactive
The Profibus DP interface has received the Global Control Clear telegram
and is waiting for the Global Control Operate telegram. In this mode, DP
communication works perfectly, however the actuator cannot be operated
via PLC. If the safety function is activated it will be initiated.
GC Clear active
Data length 0 status
DP1 data length 0 M0557
Data length 0 inactive
The Profibus DP interface receives data telegrams of the length 0. In this
mode, DP communication works perfectly, however the actuator cannot
be operated via PLC. If the safety function is activated it will be initiated.
Data length 0 active
Global Control Freeze Status
DP1 GC freeze M0558
With
Unfreeze
Global Control telegram the
Freeze
state is deactivated
again.
GC Freeze inactive
The
Freeze
Global Control telegram can be used to freeze the Profibus
DP inputs (feedback signals).
GC Freeze active
Global Control Sync Status
DP1 GC sync M059
With the
Unsync
Global Control telegram is the
Sync
state is deactivated
again.
GC Sync inactive
The
Sync
Global Control telegram can be used to freeze the Profibus DP
outputs (operation commands).
GC Sync active
Configuration data (number of input and output bytes) set by the master.
