1 Description of the MICROMASTER
PROFIBUS Option module.
The function of the PROFIBUS-DP communication board (PROFIBUS optional
board) is to provide a communications link between inverters of the
MICROMASTER 4 product range and a higher-level automated system. This
PROFIBUS variant is specific to the MICROMASTER 411 and COMBIMASTER
411 Inverters.

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

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 faultfree operation, both bus terminators must have a voltage supply at all times. The
Page 14
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 PROFIBUSDP 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
Page 18
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:

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.

milliseconds.
This represents the period of time between “setpoint arrives at DP slave” and
“updated (and referencing) actual value is made available on PROFIBUS-DP“.
The reaction time of the MICROMASTER 4 with respect to a parameter
modification (PKW) is approximately 50 milliseconds.
3.2 Acyclic data transmission
Extended PROFIBUS-DP functions (DPV1)
The PROFIBUS-DP extensions DPV1 include the definition of an acyclic data
exchange which can take place in parallel to cyclical data transmissions.
Acyclic data transfer mode allows
Ø large quantities of useful data (up to 240 bytes) to be exchanged
Ø simultaneous accessing by other PROFIBUS masters
(class 2 master, e.g. start-up tool)
Ø omission of I/O address in the SIMATIC and reduction of bus cycle time
through relocation of PKW area from the cyclical to the acyclical transmission
channel
Conversion of extended PROFIBUS-DP functionality
The different masters, or different modes of data exchange, are represented by
appropriate channels in MICROMASTER 4:
Ø Cyclical data exchange with one class 1 master
Use of DATA-EXCHANGE and PPO types according to PROFIDrive Profile.
Ø Acyclical data exchange with the same class 1 master
Use of DPV1 functions READ and WRITE
The content of the transferred data block corresponds in this case to the
structure of the parameter area (PKW) as defined in the USS specification
(with data block 100)
or
the structure of the acyclical parameter channel according to PROFIDrive
Profile, version 3.0 (with data block 47).
Ø Acyclical data exchange using a SIEMENS start-up tool (class 2 master)
The start-up tool can acyclically access parameter and process data in the
inverter.
Ø Acyclical data exchange with a SIMATIC HMI (second class 2 master)
The SIMATIC HMI can acyclically access parameters in the inverter.
Ø Instead of a SIEMENS start-up tool or SIMATIC HMI, an external master (class
2 master) as defined in the acyclical parameter channel according to
PROFIDrive Profile version 3.0 (with data block 47) can access the inverter.

HIGH LOW
Array subindex MICROMASTER 4-specific
15 8 7 0
Subindex 0- 255 Bit 7=PARA PAGE SEL
The array subindex (referred to simply as “subindex” in the PROFIDrive Profile) is
an 8-bit value which is transferred in the high-order byte (bits 8 to 15) of the
parameter index (IND) when data are transferred cyclically via PPOs. The loworder byte (bits 0 to 7) is not defined in PROFIDrive Profile version 2.0. The loworder byte of the parameter index is used on MICROMASTER 4 to be able to
address additional parameters with a number of >1999.

The array subindex is an 8-bit value which is always transferred in the low-order
byte (bits 0 to 7) of the parameter index (IND) in acyclical data exchange mode.
The Parameter Page Selection task for additional parameters is performed in this
case by the high-order byte (bits 8 to 15) of the parameter index. This structure
conforms to the USS specification.

Function of the subindex in IND
Subindex = 0 .. 254
If the subindex is transferred with values between 0 and 254 in a request, the
relevant parameter index is transferred in the case of an indexed parameter. For
the meaning of the individual indices of a parameter, please refer to the “Parameter
List” in the inverter operating instructions.
In the case of a descriptive element, the number of the required element is
transferred. The meaning of descriptive elements can be found in the PROFIDrive
Profile, version 2.0.
Subindex = 255
A value of 255 for the array subindex is a MICROMASTER 4-specific, special
function. If the array index is transferred with 255, all the indices of an indexed
parameter are transmitted simultaneously in one data block.
The function is meaningful only for acyclical data exchange mode. The structure of
the transferred data block complies with the USS specification. The maximum data
block size is 206 bytes.
Function of PARA PAGE SEL
The bit for parameter page selection functions as follows:
If it is set to 1, an offset of 2000 is applied in MICROMASTER 4 to the parameter
number (PNU) transferred in the PKW request before it is passed on.

P2000 – P3999 0 – 1999 0 – 7CF = 1
Parameter value (PWE) 3rd and 4th word
The parameter value (PWE) is always transmitted as a double word (32-bit). Only
one parameter value at a time can be transferred in a PPO telegram.
A 32-bit parameter value comprises PWE1 (high-order word, 3
rd
word) and PWE2
(low-order word, 4
th
word).
A 16-bit parameter value is transferred in PWE2 (low-order word, 4
th
word). PWE1
(high-order word, 3
rd
word) must be set to 0 on the PROFIBUS-DP master in this
case.

Rules for processing requests/responses
Ø A request or a response can only ever refer to one parameter.
Ø The master must repeat a request continuously until it has received the
appropriate response.
Ø The master detects the response to a request it has sent by
♦ evaluating the response identifier,
♦ evaluating the parameter number PNU,
♦ evaluating the parameter index IND if necessary, or
♦ evaluating the parameter value PWE if necessary.
Ø The complete request must be sent in one telegram. Request telegrams
cannot be split. The same applies to responses.
Ø In the case of response telegrams which contain parameter values, the drive
always returns the momentary parameter value when repeating response
telegrams.
Ø If no information needs to be fetched from the PKW interface in cyclical
operation (only PZD data are relevant), then the “No request” request telegram
must be issued.

!
!
Warning
♦ Make sure that the MICROMASTER 411/COMBIMASTER 411 inverter is
isolated from the electrical supply before you install or remove the
PROFIBUS-option module.
Cautions
♦ Do not
knock out cable gland blanking plates unless inverter ‘electronics’
(Filter & I/O boards) have been removed!
♦ The inverter and PROFIBUS module electronics contain static sensitive
devices therefore precautions must be taken against electrostatic discharge
(ESD) when handling the separated inverter assembly. These include not
touching the internal surfaces of the inverter and ensuring that personnel
are earthed while handling the unit. The terminal housing, including Filter
and I/O modules, contain no sensitive components and therefore no special
handling precautions are required when separated.

4.1.4 Connection of an external 24 V voltage supply
The PROFIBUS module has been designed to allow an external 24 V Power
Supply to be provided to the Profibus Module.
If this arrangement is required, it is necessary to make use of a ‘Hybrid’ Cable
which provides both communications and power supply cable cores, which is fed
into the PROFIBUS module through the module gland holes.
Recommended cable type :
PROFIBUS Cable (hybrid) : Siemens Type : 6ES7 194 -1LY10-0AA0-Z
Due to the larger cross section of this hybrid cable to standard PROFIBUS Cable, it
is recommended to use the following cable gland arrangement (not included with
PROFIBUS Module) :
a. Cable Gland M20 x 1.5 (Suggested Type : Lapp Group :
Part Nr : 53112630).
b. Gland adapter ring : M20x1.5 to M16x1.5 (Suggested type : Malux :
Part nr. : CA-740274)
This arrangement is required for each cable gland hole.
A +10 V to +24 V DC external power supply can be connected via the 11-way
terminal block, see Section 4.2.

4.2 Connecting the bus cable using RS485 bus connectors
Warning
An inverter can be switched on unintentionally if the serial bus installation is not
performed correctly. The bus must be started up by personnel who are qualified
and trained in installing systems of this type.
Terminal assignment of PROFIBUS terminals
The Options Interface board has an 11 way terminal block to provide for
connections on to the PROFIBUS system. Terminals are short-circuit-proof and
isolated.

4.2.1 Maximum cable lengths
RS-485-compliant transmission is the transmission mode used most frequently on
PROFIBUS-DP. This requires a twisted, screened copper cable with one conductor
pair.
A total of 124 devices can be connected to one PROFIBUS line. Up to 32 devices
can be interconnected in a linear structure within one bus segment. If the
configuration includes more than 32 nodes, repeaters (cable amplifiers) must be
installed to link the individual bus segments.
Maximum cable lengths are dependent on the baud rate (transmission speed).
Cable lengths specified in the table below can be guaranteed only with approved
PROFIBUS bus cables (e.g. Siemens PROFIBUS cable available under order
number (MLFB) 6XV1830-0EH10).

RS485 repeaters can be installed to increase the length of a segment.
NOTE
Observe the following cable installation rules:
Ø The bus cable must not be twisted, stretched or compressed during
installation.
Ø Supplementary constraints as regards electromagnetic compatibility must
also be observed.
Further relevant information can be found, for example, in Chapter 3 of the
Compendium (6SE7080-0QX50 Edition AE, MASTERDRIVES Document).
4.2.2 Comms Link Connector
To connect the PROFIBUS module to the inverter it will be necessary to insert the
Comms Link cable bus connector between the Inverter I/O board and the
PROFIBUS module.
The cable screening lead on the cable should be connected to the I/O board (see
Figure 4-7).
4.2.3 Connecting the Bus Cable
PROFIBUS connections to the module are made via cable glands. The cable
should be stripped back and made-off as shown in Figure 4-8.
Figure 4-8 PROFIBUS Cable Strip Lengths
PROFIBUS cables must be routed at least 20 cm (7.87 inches) from any power
cables.

4.2.4 Bus terminator
For interference-free operation of PROFIBUS-DP, the bus cable must be
terminated at both ends with bus terminating resistors. For the correct operation of
a PROFIBUS network, the first and last PROFIBUS nodes of the network must be
terminated.
Correct termination is achieved by setting the Terminator Switch to the ‘ON’
position marked on the Options Interface PCB as shown in Figure 4-9.
Figure 4-9 Switch Positions for Bus Terminating Resistors
If these bus terminators are not used, the user must ensure that a bus terminating
network is installed on the first and last bus nodes as shown in Figure 4-10.
Figure 4-10 Bus terminating network
WARNING
All stations on which a terminating resistor is activated must be supplied with power
at all times, otherwise incorrect termination will result in possible communications
errors.
4.2.5 Screening the Bus Cable / EMC precautions
The following EMC-related precautions must be taken to ensure interference-free
PROFIBUS-DP operation, particularly in RS-485 data exchange mode:
Screening
The screen of the PROFIBUS cable must be made-off within the cable gland.

!
Caution
Crossovers between bus and power cables must be laid at an angle of 90°.
Equipotential bonding
Differences in potential (e.g. due to different mains supplies) between the inverters
and the PROFIBUS-DP master must be avoided.
Ø Recommended equipotential bonding cables:
♦ 16 mm
2
Cu for equipotential bonding cables up to 200 m long
♦ 25 mm
2
Cu for equipotential bonding cables of over 200 m long
Ø Equipotential bonding cables must be routed as close as possible to signal

5 Configuration of the PROFIBUS
WARNING
Disconnect the inverter supply when installing the PROFIBUS Module.
NOTE
Before the inverter (with PROFIBUS module connected) is switched on, either a
Basic Operator Panel (BOP) or ‘Advanced Operator Panel’ (AOP) should be
inserted into the MICROMASTER 411 communications socket.
5.1 PROFIBUS address
A minimum requirement for configuring the PROFIBUS module is to establish the
PROFIBUS address setting within the network.
There are two methods of setting the PROFIBUS address; these are as follows:
Ø via jumpers on the module interface board
Ø via parameter P0918.
Figure 5-1 Jumpers and Termination switch
The PROFIBUS address can be set from 1 to 125, as shown in Table 5-1.
Table 5-1 PROFIBUS Jumper Settings
Jumper number: 1 2 3 4 5 6 7
Add to address: +1 +2 +4 +8 +16 +32 +64

Important NOTE
The inverter power supply must be switched off before any jumper settings are
changed. The changes to jumper positions do not take effect until the PROFIBUS
has been power cycled.
5.2 PROFIBUS Parameters
The parameters shown in Table 5-3 must be set to correctly configure the
PROFIBUS Module:

P0927 Modification source for parameters
r2054 (Read-only) Communication board diagnostics (see Section 8.2)
P0918 – PROFIBUS address
If address 0 is set on the option interface board (default setting), then the
PROFIBUS address can be changed using P0918.
Valid settings are 1 to 125 (default = 3).
Once a valid PROFIBUS address has been set on the jumpers, P0918 can no
longer be changed. In this case, the parameter displays the jumper set PROFIBUS
address.
The “Reset inverter parameters to factory setting” function also resets the
PROFIBUS address to 3 if it has been set originally via P0918.

P0719 – Process Data Master Control
For simple applications, P0719 can be set to 66 to select the setpoint source.
Control Word 1 and the Master Setpoint are then accepted by the PROFIBUS
optional board.
Status Word 1 and the actual main value are output via the PROFIBUS optional
board regardless of the setting in P0719.
P0719 has priority over P0700 and P1000.
P0700 and P1000 – Fast Selection
The control word and setpoint sources can be selected quickly in P0700 (select
command source) and P1000 (select frequency setpoint) respectively.
P0719 must be set to 0 when BICO technology is used with P700 and P1000.
r2050 and P2051 – BICO
Much greater flexibility is afforded by the interconnection of process data using
binectors/connectors, see description “Use of binectors and connectors” in the
reference manual.
Detailed connection of setpoints and actual values to and from the PROFIBUS
optional board is parameterized in r2050 and P2051.

Process data monitoring
Two parameters determine how process data is monitored:
Ø Threshold monitoring on the PROFIBUS optional board (standard slave
function according to PROFIBUS)
Ø Monitoring of the telegram failure time in the inverter with parameter “P2040”
The threshold monitoring function on the PROFIBUS optional board is normally
activated. It can be deactivated via the PROFIBUS master configuring tool.
NOTE
The threshold monitoring function should not be deactivated!
P2040 – Telegram Failure Time
Parameter P2040 is set to determine whether setpoint transmission via PROFIBUS
should be monitored by the inverter.
Ø P2040 = 0 means: No monitoring
Ø P2040 > 0 means: The value of “P2040” is the telegram failure time in
milliseconds. (The default setting of the parameter is a value of >0!)
Fault 0070 is activated if no new setpoints are received by the PROFIBUS optional
board within the telegram failure period.
Important NOTE
Shutdown on faults only take place if both monitoring functions are activated!
When the PROFIBUS optional board is in operation, P2040 should also be set to a
value of > 0. The process data monitoring function is thus activated/deactivated
solely via the PROFIBUS threshold monitor. Monitoring time then corresponds to
the threshold monitoring time setting + the setting in P2040.

22. Select the appropriate bus address from the scroll-down list.
23. Choose the appropriate data format; PPO3 or PPO1, or one of the custom
options for MICROMASTER 4.
PPO3 allows two process data words (PZD) corresponding to the control word and
frequency reference (outputs from the PLC to the inverter) and the status word and
actual frequency (inputs to the PLC from the inverter). PPO1 has four additional
data words that allow the inverter parameters to be read and changed. Other
formats allow additional PZD data to be sent and received, for example, if you want
to be able to read the motor current directly.
For non PPO formats word consistency is recommended. If whole consistency is
required the PLC program has to use the standard function blocks SFC14/SFC15
to read data from the inverter. The S7 commands L PIW, T PQW etc, are only
allowed with word consistency.

If required you can change the automatic assignment. In the example, the 4 PKW
words are in bytes 256 to 263 and the 2 PZD words are in bytes 264 to 267.
In Step 7, the control word and frequency reference can be represented as
PQD 264 (peripheral output double word) and the status word and actual
frequency as PID 264 (peripheral input double word).

6.2 Setting Parameters
The following parameter settings assume that the user is starting from the default
parameter settings. If you are not starting from the default parameter settings then
use the following parameters to reset all parameters to the default settings:
P0010 = 30
P0970 = 1
The parameters that require setting are as follows:
1. Set the User Access Level using P0003 = 3. This gives the user access to
all parameters in Level 1, 2 and 3.
2. Set the PROFIBUS address using P0918. Possible settings are between 1
and 125. 0, 126 and 127 are not valid addresses (2 is normally used for the
PLC).
3. The PROFIBUS address can also be set using the Jumpers as described
in Section 5.1 on page 42. The jumper settings will take effect when the
inverter is next powered up. These settings will override the settings in
P0918.
4. Set the Command Source using P0700 = 6. This sets the Command
Source to the PROFIBUS on the Comms Link.
5. Set the Frequency Setpoint using P1000 = 6. The sets the Frequency
Setpoint to the PROFIBUS on the Comms Link.
6. On completion of steps 5 and 6 full PROFIBUS control is established.
6.3 Confirmation of PROFIBUS Communications
It is recommended that you check the correct operation of the PROFIBUS control
before it is engaged to drive a motor. The following procedure should confirm the
correct functioning of the PROFIBUS control:
1. Send the following PZD words:
047E 1000
2. Monitor the frequency setpoint (0 – 12.5 Hz) using an Operator Panel.
6.4 Controlling the Inverter with a PLC
If you have chosen PP03, you will have 2 output words (PZD1 and PZD2) from the
PLC, which correspond to the inverter control word and frequency setpoint. You will
also have two input words which are the inverter status word and actual frequency.
If you chose PPO1, the first 4 input and output words are for parameter read/write
data (PKW data). The PKW output words can be set to zero at this time. The
frequency setpoint and actual value are normalized such that 4000 hex
corresponds to 50Hz. The maximum value that should be sent is 7FFF. The
normalization frequency can be changed in P2000.
Here are some typical control and status words to get started. The status words
assume the inverter has ramped up to its frequency setpoint (where applicable).
The data sequence is: control word — frequency setpoint — status word — actual

7.1 General
PROFIBUS slaves have different performance characteristics.
To ensure that each slave with its individual properties can be correctly addressed
by any master, the characteristic features of a slave are listed in its device master
data file (GSD).
Device master data file (GSD)
The device master data file for the MICROMASTER 4 PROFIBUS optional board
(SIEM80B5.GSD) is stored on the documentation CD for MICROMASTER 4.
Alternatively, it can be downloaded from the Internet (www.profibus.com).
7.2 Operation on SIMATIC S7
PROFIBUS-DP interfaces in SIMATIC S7
Suitable S7 masters are, for example, the CPUs with integrated PROFIBUS-DP
interface such as CPU315-2DP, CPU413-2DP, CPU414-2DP or CPU416-2DP etc.,
or corresponding interface boards (CPs).
The master station as well as the entire PROFIBUS network are configured in the
STEP7 hardware manager.
MICROMASTER 4 as PROFIBUS-DP slave on S7
The MICROMASTER 4 can be operated on a SIMATIC S7 as two different slave
types:
Ø As a DP slave with standard functionality
Ø As a DP slave with extended functionality for SIMATIC S7
MICROMASTER 4 as DP slave with standard functionality
The MICROMASTER 4 with standard functionality is based on the GSD. It is
displayed directly below the SIMOVERT folder in the STEP 7 HW Catalog.
The GSD file (SIEM80B5.GSD) for MICROMASTER 4 will be integrated in future
versions of STEP 7; it can be imported to other versions.
The communication board based on the integrated GSD can utilize the following
functions:
Ø PPO type 1 or 3
Ø 4 PZD for process data
Ø Acyclical communication with a SIEMENS start-up tool (e.g. STARTER) and
SIMATIC HMI
MICROMASTER 4 as DP slave with extended functionality
The extended scope of functions includes:
Ø Acyclical communication with a SIEMENS start-up tool (e.g. STARTER) and
SIMATIC HMI
Page 60
LINKS TO PROFIBUS MASTER SYSTEMS Issue 03/02
PROFIBUS Communication Module Operating instructions
60 6SE6400-5AV00-0BP0
Ø Optional configuration of process data
Ø Utilization of internode data communication
The MICROMASTER 4 with extended functionality is based on an S7-specific
configuring software add-on called the “Slave Object Manager”.
After the Slave Object Manager has been installed in STEP 7, the MICROMASTER
4 is displayed as a separate folder in the STEP 7 HW Catalog (under the
SIMOVERT folder).
The Slave Object Manager replaces and extends the functionality of the GSDbased, STEP 7-integrated option.
The Slave Object Manager is an integral component of the following products:
Ø “Drive ES Basic V5.1” 6SW1700-5JA00-1AA0
Ø “Drive ES SIMATIC V5.1” 6SW1700-5JC00-1AA0
Ø “Drive ES PCS7 V5.1” 6SW1700-5JD00-1AA0
(these products require STEP 7 version 5.1 or PCS7 version 5.1.)
Further information about configuring the data exchange between a
MICROMASTER 4 and a SIMATIC S7 can be found in the description of block
package “Drive ES SIMATIC“ or in the online help of the Slave Object Manager.
Optional configuration
Up to four process data, separated according to setpoints and actual values, can
be configured in each telegram.
The data exchange can be optionally configured for all DP masters configured with
STEP 7.
Utilization of internode data communication
This mode permits slaves to intercommunicate directly, instead of indirectly via the
PROFIBUS-DP master.
Internode communication can be utilized only if the installed PROFIBUS-DP master
supports this functionality. This includes, for example, all S7-CPUs with
“equidistance” (“clocking”) capability.
Optional configuration and internode data communication are programmed
completely on the “Configuration” card in the Slave Object Manager. The setpoints
and actual values need only be interconnected correctly in the drive.
Standard blocks for data exchange with MICROMASTER 4
The “Drive ES SIMATIC“ package contains standard function blocks which
implement the exchange of data between the drive and SIMATIC S7 in accordance
with DRIVEProfile, version 2.0 or 3.0. These blocks make it easier to write the user
program.

7.3 Exchanging data using internode communication
function
The “Internode communication” function is described in detail in PROFIDrive
Profile, version 3.0.
Internode communication enables slaves to communicate directly with one another
instead of routing data indirectly via the DP master. This function can be utilized
only in conjunction with a DP master as “synchronizer” or an S7 CPU with
“equidistance” capability.

The data is generated by the transmitter (Publisher) and received by one or several
receivers (Subscribers).
Transmitter
All input data of a DP slave with internode communication capability constitute
transmit data with respect to internode exchanges. They can be received by the DP
master or by internode-capable DP slaves. (“Input data” in the context of
PROFIBUS-DP are data output by the DP slave in the direction of the DP master).
It is not necessary to configure internode communication transmitters explicitly.
Receiver
The sources for setpoints are parameterized. The following can be selected as
sources:
Ø The output data of the DP master
Ø The input data of a DP slave as an internode communication transmitter
(actual values in the case of drives).
Master output data and slave input data can be mixed as required (with word
granularity). (“Output data” in the context of PROFIBUS-DP are data which the DP
slave receives from the DP master).

62 6SE6400-5AV00-0BP0
Logical communication relationships with internode communication
You can configure the communication relationships between DP slaves using the
internode communication function, e.g.:
Ø “Broadcast principle”: One master drive specifies a master setpoint for all slave
drives.
Ø “Peer-to-peer principle”: A setpoint is forwarded from one drive to the next.
A communication relationship is also referred to as a “channel” or “link”.
Quantity framework from slave viewpoint
The MICROMASTER 4 has a total of 4 words of receive data (setpoints) and 4
words of transmit data (actual values).
A source-destination relationship can be defined for this type of data word, e.g.
setpoint 1 is sent by DP master; setpoint 2 is sent by an internode-capable slave
and not by the DP master.
Number of transmit channels:
A broadcast channel which the DP master and any number of DP slaves can
receive, i.e. a maximum of 4 data words on MICROMASTER 4
Number of receive channels:
Maximum four, i.e. the four setpoints could come from four different sources on the
PROFIBUS.
Prerequisites
Ø STEP 7, version 5.1 and later
Ø Drive ES SIMATIC V5.1
Ø S7 PROFIBUS master system with “Equidistance” capability (clocking)
Ø Internode-capable DP slaves as communication partners
(e.g. drives or ET200)
Internode communication is programmed with the SlaveOM in the "Configuration"
screen.
The sequence of configuring operations is described in the documentation for Drive
ES SIMATIC.

You can access a MICROMASTER 4 directly using a SIMATIC HMI as the
PROFIBUS master.
A MICROMASTER 4 reacts to a SIMATIC HMI in the same way as it does to a
SIMATIC S7. As regards access operations to drive parameters, the following
simple formula applies:
Ø Parameter number = data block number
Ø Parameter subindex = data block offset
All SIMATIC OPs and TDs with final digit 7 are suitable.

NOTE
Ø You can operate a SIMATIC HMI and a drive together independently of the rest
of the automation system.
Ø A simple "point-to-point" link with just two nodes is possible.
Ø The HMI "Variables" functions can be used for drives. Other functions cannot
be used (e.g. "Messages" or "Recipes").
Ø Individual parameter values can be accessed, but access operations to
complete arrays, descriptions or texts are not possible.
Ø The diagnostic output on the SIMATIC HMI is limited. In the case of accessing
difficulties, the diagnostic parameters of the communication board, i.e.
r2054.03 and ff., will be helpful, see Chapter 8 "Diagnostics and
Troubleshooting".

7.5 Operation on external master systems
The MICROMASTER 4 can operate only as a standard DP slave on an external
master.
Required GSD file
The device master file (GSD file) contains all information required by a DP master
system to integrate the MICROMASTER 4 into its PROFIBUS-DP configuration as
a standard DP slave.
Provided the external master system allows the direct integration of GSD files, file
SIEM80B5.GSD can be copied directly into the appropriate subdirectory.
If the external master is not compatible to this extent, the necessary information
must be derived manually from file SIEM80B5.GSD.
Exchanging data with MICROMASTER 4 without standard data blocks
In cases where block package "Drive ES SIMATIC“ cannot be used, the user
program must adhere to the system properties with respect to data consistency.
This means in particular that system functions of SIMATIC S7 (SFC14
(DPRD_DAT) and SFC15 (DPWR_DAT)) or corresponding means must be used to
access > 2 words for the PKW and PZD areas.
In this case, the PKW area and PZD area must be regarded as two mutually
independent, consistent data areas.
PKW PZD
PPO1 (4 words) (2 words)
PPO3 − (2 words)
Extended PZD:
(4 words) (4 words)
− (4 words)

8 Diagnostics and Troubleshooting
There are two types of diagnostic display:
Ø Alarm numbers
Ø Diagnostic parameter
8.1 Diagnostics using alarm number
(Alarms and Faults)
If alarms and faults occur on the PROFIBUS communication link, corresponding
alarm numbers are displayed on the inverter (BOP/AOP).
8.1.1 Alarms
Table 8-1 Alarm Displays on Inverter
Alarm
Number
Meaning
A700 Cause: The parameter or configured settings by the PROFIBUS master are
invalid.
Remedy: Correct the PROFIBUS configuration
A702 Cause: The link to the PROFIBUS is interrupted.
Remedy: Check connector, cable and PROFIBUS master
A703 Cause: No setpoints, or invalid setpoints (control word = 0) are being
received from the PROFIBUS master
Remedy: Check setpoints from the PROFIBUS master. Switch SIMATIC CPU
to "RUN".
A704 Cause: At least one configured internode transmitter is not yet active, or has
failed.
Remedy: Activate internode transmitter.
A705 Cause: No actual values received from inverter.
Remedy: None (fault is in inverter)
A706 Cause: PROFIBUS-DP communication board: Software error.
Remedy: None (fault on the PROFIBUS-DP communication board, for details
see diagnostic parameter)
A710 Cause: Inverter has detected failure of communication link to PROFIBUS-
DP communication board
Remedy: None (communication board may need to be replaced)
A711 Cause: Invalid value of a CB?? parameter.
Remedy: Check P0918 (PROFIBUS address) and P2041 (communication
board parameters)
