Only by confirming the register "Reset counter" by pressing the "Reset
maintenance counter" key will the following maintenance counters be
reset:
Number of 100% strokes (STRKS)
S
Number of changes of direction (CHDIR)
S
Number of fault messages (\CNT)
S

The following target modes (operating modes) are available:
Automatic
S
Manual
S
Local overlay (LO))
S
Not in service (OS)
S
Note that the target modes refer to the operating modes of the function
blocks in the PROFIBUS PA block model and are not interchangeable
with the positioner operating modes "Automatic" and "Manual".
The above target modes take effect when the positioner is in automatic
operation (AUT). If the positioner is in manual mode (MAN) they will
take effect only after a local changeover to automatic operation (AUT).
These target modes are saved in the positioner and are non-volatile in
the event of power loss.
Provided the positioner has not yet been linked in as a slave in cyclical
operation, a cyclic setpoint can be sent to it using PDM.
Perform the following settings:
Open the "Operating mode" register
S
Set the target mode to "Automatic"
S
Enter a value between 0 and 100% for the setpoint, quality "Good"
S
and status "OK".
Upload the settings into the positioner.
S
The positioner will now control to the desired setpoint until a cyclic
master takes up communication with this slave or the positioner is lo-
cally set to manual mode.
