1. A clear text operator panel
(OPM2) is required to set the
COMBIMASTER parameters
prior to connecting the
PROFIBUS module.
2. The PROFIBUS Module may only
be connected or disconnected
from the drive when the drive is
powered off.
3. The PROFIBUS module must only
be connected to the drive with the
cable supplied for the purpose.
4. The PROFIBUS module cannot be
used simultaneously with the
Clear Text Display module.
The data structure for communication over
PROFIBUS-DP can be either PPO type 1 or
PPO type 3 as specified in VDI/VDE 3689.
This means in practice that process data
(control words, set-point in the transmitted
telegram and status words, actual values in the
received telegram) is always sent.

Parameter data exchange may, however, be
blocked if bus or PLC memory space is at a
premium. The data structure and thus the
PPO type is normally specified by the bus
master. If no PPO type is specified (e.g. if a
combined DP/FMS bus master is used), then
the default PPO type is type 1 (parameter data
enabled). Parameter write access over the
serial link can be enabled or blocked as
required.
