■ PROFIBUS-DP communication board CBP2
PROFIBUS-DP message
frame
Data are exchanged in mes-
PKW PZD
sage frames. Each message
frame contains useful data
which are divided into two
groups:
PKE IND PWE
PZD1
STW1
ZSW1
PZD2
HSW PZD3
HIW
PZD4 PZD5 PZD6 PZD7 PZD8 PZD9 PZD10

2. Process data (PZD)
The PKW area contains all
PPO1
transfer data which are needed
to read or write parameter val-
PPO2
ues or read parameter properties.
PPO3
The PZD area contains all the information
needed to control a
variable-speed drive. Control
PPO4
information (control words) and
setpoints are passed to the
PPO5
slaves by the PROFIBUS-DP
master. Information about the
status of slaves (status words)
PKW: Parameter ID value
PZD: Process data
PKE: Parameter ID
STW: Control word 1
ZSW: Status word 1
HSW: Main setpoint
as well as actual values are
IND: Index
HIW: Main actual value
transferred in the opposite direction.
PWE: Parameter value
The length of the PKW and PZD
components in the message
frame as well as the baudrate,
Fig. 4/25
Useful data transfer according to “PROFIBUS profile for variable-speed drives PROFIDRIVE”
are determined by the master.
Only the bus address and, if
Pin assignments on X488 connector
necessary, the message frame
failure time are set on the
Pin Designation Meaning
slaves.

1) For the installation of the CBP2 board in the
SIMOREG unit, the Local Bus Adapter ADB
and the adapter board ADB are additionally
required. These must be ordered separately.
