PROFIBUS Communication Module Operating instructions
12 6SE6400-5AV00-0BP0
1.1 Technical data
PROFIBUS is contained within the cover of the Options module attached to the
side of the inverter. The PROFIBUS unit is powered directly from the inverter and
therefore needs no additional external supply during normal operation. Provision
exists on PROFIBUS for the connection of an external control supply, which can be
used to apply power to the Inverter control circuits.
The board is connected to the PROFIBUS system via an 11 – way Communication
Interface connector. All connections to this RS485 interface are short-circuit-proof
and isolated.
1.2 Functionality
Ø Cyclical process data exchange (PZD) in accordance with PROFIDrive Profile,
version 2.0 or version 3.0
Ø Parameter accessing:
Cyclical accessing of parameters (PKW) in accordance with PROFIDrive
Profile version 2.0
or
Acyclical accessing of parameters (data block 47) in accordance with
PROFIDrive Profile version 3.0
Ø Acyclical accessing of parameters (data block 100/data block 47) for the
purpose of exchanging parameter values with a SIMATIC S7 CPU
(Drive ES SIMATIC function block package)
Ø Acyclical accessing of parameters for SIMATIC HMI or SIEMENS Drive
STARTER tool.
Ø Support of PROFIBUS control commands SYNC and FREEZE for
synchronized data transfer between the master and several slaves
Ø Internode communication for direct exchange of process data between
PROFIBUS slaves (only in conjunction with SIMATIC S7 at the present time).

Issue 03/02 DEFINITION
PROFIBUS Communication Module Operating instructions
6SE6400-5AV00-0BP0 13
2 General Definition of PROFIBUS-DP
2.1 Definition
PROFIBUS is an international, open field bus standard widely used in the fields of
production and process automation. The bus is guaranteed brand-neutral and
open by virtue of its compliance with international standards EN 50170 and IEC
61158.
PROFIBUS-DP is a PROFIBUS communication profile optimized for high-speed,
time-critical data transmission at field level using low-cost connections.
PROFIBUS-DP is a suitable substitute for conventional, parallel 24 V signal
transmission systems in manufacturing, as well as for analog 4 to 20 mA signal
transmission systems in process automation.
PROFIBUS is a multi-master system, in other words, it is a bus on which several
automation, engineering or visualization systems can operate together with the
associated distributed field devices. In the context of PROFIBUS, master and
slave devices are defined as follows:
Ø Master devices control data traffic on the bus; they are also referred to as
“active” nodes. A master may transmit messages without prior receipt of an
external request provided that it has bus access authorization (token).
There are two classes of master:
♦ Class 1 master:
These are central automation stations (e.g. SIMATIC S5, S7 and
SIMADYN D), which exchange information with slaves in predefined
message cycles.
♦ Class 2 master:
These are programming, configuring or operator control and monitoring
systems that are used to configure or start up or monitor the plant in
operation.
Ø Slave devices are field devices such as drives (MICROMASTER 4), I/O
devices and valves. They never receive bus access authorization, i.e. they may
only acknowledge received messages or return information to a master on
request. Slave devices are also referred to as “passive” nodes.
2.2 RS-485 transmission system
Criteria such as high transmission speed and simple, low-cost installation are of
critical importance in the selection of the transmission system. The RS-485
requires a screened copper cable with twisted-pair wires.
Transmission speeds can be selected within the 9.6 kbaud to 12 Mbaud range. It is
set globally for all devices on the bus during system start-up.
2.2.1 General information about RS-485 transmission installation
All devices are connected in a bus structure (line). Up to 32 nodes (master or
slaves) can be interconnected within one segment. The bus is terminated by an
active bus terminator at the beginning and end of each segment. To ensure fault-
free operation, both bus terminators must have a voltage supply at all times. The

DEFINITION Issue 03/02
PROFIBUS Communication Module Operating instructions
14 6SE6400-5AV00-0BP0
bus terminators can normally be activated either in the devices themselves or on
the bus termination connectors.
To accommodate more than 32 nodes or increase the scope of the network,
repeaters (cable amplifiers) can be installed to link the individual bus segments.
2.2.2 Bus accessing mode
PROFIBUS operates according to the token passing principle, i.e. the active
stations (masters) receive transmit authorization in a logical ring for a defined time
window. Within this window, the master can communicate with other masters or
exchange data with the relevant slaves in a subordinate master-slave process.
PROFIBUS-DP primarily utilizes the master-slave process for this purpose; in most
cases, it exchanges data with drives such as MICROMASTER 4 cyclically.
2.3 Data exchange via PROFIBUS-DP
Data can be exchanged between the higher-level systems (e.g. SIMATIC,
SIMADYN D, PC/PGs) and the drives very quickly via the PROFIBUS-DP. Drives
are always accessed according to the master-slave principle. Drives are always
slave nodes. Each slave can be identified by its unique address on the bus (MAC).

Figure 3-1 PROFIBUS-DP data channels
3.1 Cyclical data of MICROMASTER 4 via PROFIBUS-DP
MICROMASTER 4 is controlled via the cyclical PROFIBUS-DP channel. This
channel can be used to exchange parameters.
The structure of useful data for the cyclical channel is defined in the PROFIDrive
Profile, version 2.0, and referred to as the Parameter Process data Object (PPO).
PROFIDrive Profile defines for the drives the useful data structure with which a
master can access the drive slaves using the cyclical data communication method.
3.1.1 Useful data structure as defined in PROFIDrive Profile 2.0 and 3.0
Useful data structure according to PPOs
The useful data structure for cyclical data traffic is divided into two areas, which
can be transmitted in each telegram as follows:
Ø Process data area (PZD), i.e. control words and setpoints, or status
information and actual values
Ø Parameter area (PKW) for reading/writing parameter values, reading out
faults, or reading out information about the properties of a parameter
such as, for example, min/max limits, etc.
With which PPO type (see next page) the inverter is addressed by the PROFIBUS-
DP master can be defined in the configuration data for the master when the bus
system is started up. Which type of PPO is selected depends on the function of the

COMMUNICATION Issue 03/02
PROFIBUS Communication Module Operating instructions
18 6SE6400-5AV00-0BP0
drive in the automation network. Process data is always transferred. It is processed
as top priority in the shortest time slice in the drive.
Process data is used to control the drive in the automation network, On/Off
commands, setpoint inputs, etc.
The parameter area enables the user to access all parameters stored in the
inverter via the bus system. For example, to read out detailed diagnostic
information, faults messages, etc.
Telegrams for cyclic data transmission thus have the following basic structure:
Protocol frame Useful data Protocol frame
(header) Parameter (PKW)1Process data (PZD) (trailer)
PPO
1PKW: Parameter identifier value
Five types of Parameter Process data Object (PPO) are defined (see Figure 3.2)
according to PROFIDrive Profile, version 2.0 and these contain:
Ø Useful data without parameter area, with two or six words of process data or
Ø Useful data with parameter area, with two, six or ten words of process data.

Note:
MICROMASTER 4 supports only PPO1 and PPO3 (shaded areas).
The useful data structure has been subdivided into the PKW and PZD areas in
order to satisfy different functional requirements of the communication system.
Parameter data area (PKW)
The PKW (parameter identifier value) telegram section can be used to monitor
and/or change any parameter in the inverter. The request/response identifier
mechanisms required to do this are described in Section 3.4 “PKW mechanism”.
Process data area (PZD)
Control words and setpoints (requests: Master →inverter) and status words and
actual values (responses: Inverter →master) can be transmitted in the process
data area.
The transferred process data do not take effect until the bits used in the control
words, setpoints, status words and actual values have been routed in the inverter
as described in Section “Process data connections” of the reference manual.

COMMUNICATION Issue 03/02

Extended configuration
In addition to the PPO types, cyclical data can also be configured optionally.
Up to four process data words, with a different number of setpoints and actual
values if desired, can be configured on the MICROMASTER 4. The areas of
consistency can be set flexibly.
A parameter area (PKW) can be configured irrespective of the number of process
data.
