B, MOVITRAC® B and PROFINET

The behavior of the inverter which forms the basis of PROFINET operation, the so­called unit profile, is independent of any particular fieldbus and is therefore a uniform
feature. This allows the user to develop fieldbus-independent drive applications. This
makes it much easier to change to other bus systems, such as DeviceNet (option DFD).

3.3.2 Access to all information

Introduction

Characteristics

MOVIDRIVE
and functions via the PROFINET interface. The drive inverter is controlled via fast, cyclic
process data. Via this process data channel, you can enter setpoints such as the set­point speed, ramp generator time for acceleration / deceleration, etc. as well as trigger
various drive functions such as enable, control inhibit, normal stop, rapid stop, etc. At
the same time you can also use this channel to read back actual values from the drive
inverter, such as actual speed, current, unit status, error number or reference signals.

3.3.3 Monitoring functions

Using a fieldbus system requires additional monitoring functions for the drive technolo­gy, for example, time monitoring of the fieldbus (fieldbus timeout) or rapid stop concepts.
You can, for example, adapt the monitoring functions of MOVIDRIVE
specifically to your application. You can determine, for instance, which of the drive in­verter’s error responses should be triggered in the event of a bus error. A rapid stop
makes sense for many applications, although this can also be achieved by 'freezing' the
last setpoints so the drive continues operating with the most recently valid setpoints
(such as with a conveyor belt). As the range of functions for the control terminals is also
guaranteed in fieldbus mode, you can continue to implement rapid stop concepts using
the terminals of the drive inverter, irrespective of the fieldbus used.

Safety concept for PROFIsafe fieldbus interfaces

4 Integrated Safety Technology

4.1 Safety concept for PROFIsafe fieldbus interfaces

• Within the DFS.. PROFIsafe interface, PROFIsafe fieldbus interfaces are equipped
with an integrated safety-oriented electronics components with a failsafe output
(F-DO). The safety concept of this subassembly is based on the fact that there is a
safe state for all safety-oriented process values. For the DFS.. PROFIsafe interface,
this is the value "0" for the F-DO output.

• The following requirements are fulfilled by means of a 2-channel redundant system
structure of the safety component with suitable monitoring mechanisms:

• SIL3 according to EN 61508

• Category 4 according to EN 954-1

• Performance level e according to EN ISO 13849-1
When the system detects a fault, the system responds by reverting to a safe status.

This makes the safety function available in the form of a failsafe input connected to
a higher-level safety control via the PROFIsafe communication. The safe output on
the safety component of the DFS interface is neither evaluated locally nor processed
logically.

• The safe output F-DO can be used to disable the 24 V input "Safe stop" at X17 of the
MOVIDRIVE

Safety concept for MOVIDRIVE® and MOVITRAC®

4.2 Safety concept for MOVIDRIVE® and MOVITRAC

• In case of danger, any potential risk related to a machine must be eliminated as
quickly as possible. Standstill with restart prevention is generally the safe condition
for preventing dangerous movements.

• The MOVIDRIVE
ized by the optional connection of an external failsafe, approved emergency stop re­lay (according to safety category 3, EN 954-1). The safety relay disconnects all active
elements (disconnection of the safety-relevant 24 V power supply of the output stage
control) that generate the pulse trains to the power output stage (IGBT) when a con­nected control device (E-STOP button with latching function) is activated.

• Disconnecting the 24 V at the positive and negative poles ensures that the supply
voltages required for operating the inverter and consequently for generating a rotat­ing field of pulse patterns (which allow the generation of a rotating field) are safely
interrupted. Automatic restart is prevented in this way.

• Instead of galvanic separation of the drive from the power supply by means of relays
or switches, the disconnection of the 24 V supply described here safely prevents the
control of the power semiconductors in the drive inverter. This process disconnects
the rotating field generation for the respective motor. The individual motor cannot de­velop any torque in this state even though the line voltage is still present.

• The requirements for the safety relay are clearly defined in the following sections and
must be strictly observed.

Using a suitable external circuit via a safety relay with

– Approval for at least safety category 3
– Disconnection for at least safety category 3

Allows for operating the MOVIDRIVE
ers with safe disconnection according to stop category 0 or 1 (to EN 60204-1)
and ensures protection against restart according to safety category 3 (to
EN 954-1).

4.2.1 Limitations

WARNING

• If the DC 24 V link voltage is safely disconnected a t the positive pole only, no
test pulses must be applied to this pole in disconnected condition.

• The safety concept is only suitable for performing mechanical work on driv­en system/machine components.

• A system/machine-specific risk analysis must be carried out by the sys­tem/machine manufacturer and taken into account for the use of the
MOVIDRIVE

• When the 24 V voltage supply is disconnected, mains supply voltage is still
present on the drive inverter’s DC link.

• If work is carried out on the electrical section of the d rive syst em, the supply
voltage must be disconnected using an external maintenance switch.

accordance with IEC 60999.

• The maximum current load of the F-DO safety-related binary output is DC 1 A.

• The safety-related binary output is 2-pole, designed as P-M switch, and controlled
via PROFIsafe

• An actuator must generally be connected with the safe output F-DO with a 2-pole
connection between the P switch output and the M switch output (F-DO_P and
F-DO_M).

• It is not permitted to make a 1-pole connection between F-DO_P and the GND refer­ence potential as doing so would cause an error as soon as the output is controlled.

• Internal testing of the safe output is cyclical. However, when decoupling takes place,
the test pulses at the connection terminals are not visible and need not be taken into
account during operation.

5.1.2 DC 24 V voltage supply

The 24 V supply voltage(s) of the DFS21B and all stations connected to the fieldbus
must be designed as safety extra-low voltage. The voltage must lie within the limits de­fined in the technical data. In addition, the following voltage values must not be exceed­ed if a fault occurs (according to EN 60950): Max. DC 60 V, max. DC 120 V for 200 ms.

Assembly and Installation Notes

Installing the DFS21B option card in MOVITRAC® B

Please note:

• Use a 2x2 core twisted pair and shielded copper cable (data transmission cable with
braided copper shield). Connect the shield flatly on both sides of the electronics
shield clamp of MOVITRAC
ble must meet the following specifications:

– Cable cross section 0.25 mm
– Line resistance 120 Ω at 1 MHz
– Capacitance per unit length ≤ 40 pF/m at 1 kHz

Suitable cables are CAN or DeviceNet cables.

• The permitted total cable length depends on the baud rate setting of the SBus:
– 250 kBaud: 160 m

– 500 kBaud: 80 m
– 1000 kBaud: 40 m

• Connect the system bus terminating resistor (S1 = ON) at the end of the system bus
connection. Switch off the terminating resistor on the other units (S1 = OFF). The
DFS21B gateway must always be connected either at the beginning or the end of the
system bus connection and feature a permanently installed terminating resistor.

Wiring diagrams for safe technology

F-DO connection • The safety-related binary output F-DO is 2-pole, designed as P-M switch, and con-

trolled via PROFIsafe

• An actuator must generally be connected with the safe output F-DO with a 2-pole
connection between the P switch output and the M switch output (F-DO_P and
F-DO_M).

• It is not permitted to make a 1-pole connection between F-DO_P and the GND refer­ence potential as doing so would cause an error as soon as the output is controlled.

• Internal testing of the safe output is cyclical. However, when decoupling takes place,
the test pulses at the connection terminals are not visible and need not be taken into
account during operation.

Internal tests and monitoring processes are able to detect various external faults:
When the output is switched on, the following faults can be detected:

• Short circuit between P output and reference potential

• Short circuit between M output and DC +24 V supply voltage

• Short circuit between P output and M output

When the output is switched off, the following faults can be detected:

• Short circuit between P output and reference potential

• Short circuit between M output and reference potential

• Short circuit between P output and DC +24 V supply voltage

• Short circuit between M output and DC +24 V supply voltage

®

by a higher-level safety controller.

Whenever the system detects a fault, it reverts to a safe status, i.e. all safety-related pro­cess values (F-DO) are set to "0". In addition, the safety component is passivated. The
fault is indicated by the "FS" LED (failsafe status) (→ page 34).

The 24 V supply voltage(s) of the DFS21B and all stations connected to the fieldbus
must be designed as safety extra-low voltage. The voltage must lie within the limits de­fined in the technical data. In addition, the following voltage values must not be exceed­ed if a fault occurs (according to EN 60950): Max. DC 60 V, max. DC 120 V for 200 ms.

Shielding and routing bus cables

6.7 Shielding and routing bus cables

Only use shielded cables and connection elements that meet the requirements of cate­gory 5, class D according to IEC 11801 edition 2.0.

Correct shielding of the bus cable attenuates electrical interference that can occur in in­dustrial environments. The following measures ensure the best possible shielding:

• Manually tighten the mounting screws on the connectors, modules, and equipotential
bonding conductors.

• Use only connectors with a metal housing or a metalized housing.

• Connect the shielding in the connector over a wide surface area.

• Apply the shielding of the bus cable on both ends.

• Route signal and bus cables in separate cable ducts. Do not route them parallel to
power cables (motor leads).

• Use metallic, grounded cable racks in industrial environments.

• Route the signal cable and the corresponding equipotential bonding close to each
other using the shortest possible route.

• Avoid using plug connectors to extend bus cables.

• Route the bus cables closely along existing grounding surfaces.

WARNING

In case of fluctuations in the ground potential, a compensating current may flow via the
bilaterally connected shield that is also connected to the protective earth (PE). Make
sure you supply adequate equipotential bonding in accordance with relevant VDE reg­ulations in such a case.

TCP/IP addressing and subnetworks

6.8 TCP/IP addressing and subnetworks

Introduction The settings for the address of the IP protocol are made using the following parameters:

• IP address

• Subnet mask

• Standard gateway

The addressing mechanisms and subdivision of the IP networks into subnets are ex­plained in this chapter to help you set the parameters correctly.

IP address The IP address is a 32-bit value that uniquely identifies a node in the network. An IP ad-

dress is represented by four decimal numbers separated by decimal points.
Example: 192.168.10.4
Each decimal number stands for one byte (= 8 bits) of the address and can also be rep-

resented using binary code (→ following table).

Byte 1 Byte 2 Byte 3 Byte 4

11000000 . 10101000 . 00001010 . 00000100

6

The IP address comprises a network address and a node address (→ following table).

Network address Node address

192.168.10 4

The part of the IP address that denotes the network and the part that identifies the node
is determined by the network class and the subnet mask.

Node addresses cannot consist of only zeros or ones (binary) because they represent
the network itself or a broadcast address.

Network classes The first byte of the IP address determines the network class and as such represents

the division into network addresses and node addresses.

Value range
Byte 1

0 ... 127 A 10.1.22.3 10 = Network address

128 ... 191 B 172.16.52.4 172.16 = Network address

192 ... 223 C 192.168.10.4 192.168.10 = Network address

Network class

Complete network address
(Example)

Meaning

1.22.3 = node address

52.4 = node address

4 = node address

This rough division is not sufficient for a number of networks. They also use an explicit,
adjustable subnet mask.

Subnet mask A subnet mask is used to divide the network classes into even finer sections. Like the

IP address, the subnetwork mask is represented by four decimal numbers separated by
decimal points. Every decimal number stands for one byte.

Example: 255.255.255.128
Each decimal number stands for one byte (= 8 bits) of the subnet mask and can also be

represented using binary code (→ following table).

Byte 1 Byte 2 Byte 3 Byte 4

11111111 . 11111111 . 11111111 . 10000000

Assembly and Installation Notes

TCP/IP addressing and subnetworks

If you compare the IP addresses with the subnetwork masks, you see that in the binary
representation of the subnetwork mask all ones determine the network address and all
the zeros determine the station address (→ following table).

Byte 1 Byte 2 Byte 3 Byte 4

IP address

Subnet mask

The class C network with the address 192.168.10. is further subdivided into

255.255.255.128 using the subnet mask. Two networks are created with the address

192.168.10.0 and 192.168.10.128.

The following node addresses are permitted in the two networks:

• 192.168.10.1 ... 192.168.10.126

• 192.168.10.129 ... 192.168.10.254

The network nodes use a logical AND operation for the IP address and the subnet mask
to determine whether there is a communication partner in the same network or in a dif­ferent network. If the communication partner is in a different network, the standard gate­way is addressed.

Standard gateway The standard gateway is also addressed via a 32-bit address. The 32-bit address is rep-

resented by four decimal numbers separated by decimal points.
Example: 192.168.10.1
The standard gateway establishes a connection to other networks. In this way, a net-

work node that wants to address another node can use a logical AND operation with the
IP address and the subnetwork mask to decide whether the desired node is located in
the same network. If this is not the case, the node addresses the standard gateway
(router), which must be part of the actual network. The standard gateway then takes on
the job of transmitting the data packages.

Setting the IP address parameters via DCP

6.9 Setting the IP address parameters via DCP

Initial startup For PROFINET IO, the IP address parameters are determined via the "DCP" protocol

(Discovery and Configuration Protocol). DCP operates with device names. The device
name uniquely identifies a PROFINET IO node in the network. It is identified with the
PROFINET IO controller during the configuration of the node and also set using the con­figuration software on the PROFINET IO device. With the aid of the device name, the
controller identifies the device during startup and transfers the corresponding IP address
parameters. Settings directly on the slave are no longer required. The basic procedure
is described with SIMATIC STEP 7 as an example in chapter "Configuration with
PROFINET" (→ section "Assigning the PROFINET device name").

6

Resetting the IP
address
parameters

If you do not know the IP address parameters and cannot access the inverter using the
serial interface or the DBG60B keypad, you can reset the IP address parameters to the
default values using the DIP switch 'Def IP'.

This action resets the DFS21B option to the following default values:

• IP address: 192.168.10.4

• Subnet mask: 255.255.255.0

• Default gateway: 1.0.0.0

• PROFINET device name: PNETDeviceName

Proceed as follows to reset the IP address parameters to the default values:

• Switch off the 24 V DC supply voltage and the mains voltage.

• Set the DIP switch "Def IP" on the DFS21B option to "1."

• Switch the DC 24 V supply voltage and the line voltage back on.

• Wait until the DFS21B option has booted up. The "RUN" LED is green when the op­tion is ready.

You can now access the inverter via the IP address 192.168.10.4. Proceed as follows
to set new IP address parameters:

• Start a web browser and access the homepage of the DFS21B option or start
MOVITOOLS

• Select the required address parameters.

• Set the DIP switch "Def IP" on the DFE32B option to "0."

• The new address parameters are adopted after the device is switched off and
switched on again.

Creating a new
project

Start the SIMATIC Manager and create a new project. Select your control type and add
the required modules. The OB82, OB86 and OB122 operation modules are particularly
useful.

The OB82 operation module makes sure that the controller does not go to 'STOP' for
so-called diagnostic alarms. The OB86 operation module indicates the failure of decen­tralized periphery units. The OB122 operation module is called up if the controller cannot
access data of a station of the decentralized periphery. This can occur when, for exam­ple, the DFS21B is ready for operation later than the control system.

• Start STEP7 HWCONFIG and select the PN-IO slot in the control rack.

• Add a PROFINET IO system by right-clicking the context menu with your mouse.
Specify an IP address for the PROFINET IO controller when doing this. Add a new
PROFINET subsystem using the [Ethernet] button.

General
information

The inverter must be given a specific PROFINET configuration by the IO controller to
define type and number of input and output data words used for the transmission. You
have the opportunity to control the drives via process data and to read and write all pa­rameters of the fieldbus interface in an acyclic way.

The following figure describes the data exchange between the programmable controller
(IO controller), the fieldbus interface (IO device) and an inverter with process data chan­nel.

Configuring the
process data

62258AXX

The PROFINET interface allows for different configurations for the data exchange be­tween IO controller and IO device. The configurations are determined by the default pro­cess data width for SEW inverters of three process data words. The fieldbus interface
then distributes these process data words to the individual devices. The PROFINET in­terface accepts 1×3 to 8×3 process data words.

INFORMATION

3 PDs are always assigned to any SBus node.

There are several entries.

• Copy the required entry to the PROFINET IO system via drag & drop:
– Select "Gateway DFS21B V1.2" [2] if your controller supports topology detection.

– Select "Gateway DFS21B V1.1 OLD" if your controller does not support topology

detection.

• Assign the name of the PROFINET node.
This name must later correspond to the PROFINET unit name specified in the

DFS21B.

• The inverters connected to the gateway are represented in PROFINET as of slot 2.
Delete the entries for the respective slots depending on the number of connected in­verters (e.g. slot 2 to slot 7 for a configuration of 5 inverters).

• Move the entry "AS 1 Drive (1x3PD)" to the free slots.

• Specify the I/O and periphery addresses for the configured drives and save your con­figuration.

Auto setup for gateway operation

7.2 Auto setup for gateway operation

The auto setup function enables startup of the DFS21B as gateway to be performed
without a PC. It is activated via the auto setup DIP switch (see chapter "Installing the
DFS21B/UOH11B gateway" on page 21).

INFORMATION

Switching on the Auto-setup DIP switch causes the function to be performed once.
The Auto setup DIP switch must then remain in the ON position. The function can
be reactivated by turning the DIP switch off and back on again.

As a first step, the DFS21B searches for drive inverters on the SBus below its hierarchi­cal level. This process is indicated by the H1 LED (system bus error) flashing briefly. Dif­ferent SBus addresses must be set for the drive inverters (P813). We recommend as­signing the addresses beginning with address 1 in ascending order based on the ar­rangement of inverters in the switch cabinet. The process image on the fieldbus side is
expanded by three words for each detected drive inverter.

The H1 LED remains lit if no drive inverter was located. A total of up to eight drive invert­ers is taken into account. The following figure shows the process image for three drive
inverters with three words each of process output data and process input data.

Following the search, the DFS21B cyclically exchanges 3 process data words with each
connected drive inverter. The process output data are fetched from the fieldbus, divided
into blocks of three and transmitted. The drive inverters read the process input data, put
them together and send them to the fieldbus master.

The cycle time of the SBus communication is 2 ms per node at a baud rate of 500 kbit/s
without any additional engineering activities.

For an application with 8 inverters on the SBus, the cycle time of the process data up­date is then 8 x 2 ms = 16 ms.

INFORMATION

Perform auto setup again in the following cases, since the DFS21B stores these val­ues once during auto setup. All devices installed at the SBus must be switched on. At
the same time, the process data assignments of the connected drive inverters may not
be changed dynamically after Auto setup.

• If you change the process data assignment of the drive inverters connected to the
DFS21B.

• If you changed the SBus address of one of the connected devices.

• If you add or remove devices.

To control the drive inverter via PROFINET, you must first switch the drive inverter to

For safety reasons, you must also enable the drive inverter at the terminals for control
via the fieldbus system. Therefore, you must wire and program the terminals in such a
way that the drive inverter is enabled via the input terminals. For example, the simplest
way of enabling the inverter at the terminals is to connect the DIØØ (function/CON­TROLLER INHIBIT) input terminal to a DC +24 V signal and to program input terminals

operation in an F parameter block to the DFS21B option. The
parameters will then be checked for plausibility in the safety-oriented part of the
DFS21B. The DFS21B does not start data exchange on PROFINET until this F-param­eter block is acknowledged positively.

Below is a list of the safety-oriented parameters which are passed on to the DFS21B
option. Depending on the bus system being used, the following parameters are avail­able.

PROFIsafe parameters Bus system

PROFINET IO
F_Check_SeqNr Not installed
F_SIL fix
F_CRC_Length fix
F_Par_Version fix
F_Source_Add fix
F_Dest_Add Variable
F_WD_Time Variable

This parameter allows F stations to check whether the safety category matches that of
the F host. Depending on the risk, different safety circuits with different safety classes
SIL 1 to SIL 3 (SIL = Safety Integrity Level) apply in these safety-relevant cases.

The DFS21B option supports the following setting:

• F_SIL = SIL 3

"F_CRC_Length"
parameter

"F_Par_Version"
parameter

"F_Source_Add"
parameter

Depending on the length of the F user data (process values) and the PROFIsafe version,
the length of the required CRC check value varies. This parameter communicates the
anticipated length of the CRC2 key in the safety telegram to the F component.

The DFS21B option handles user data that is less than 12 bytes in length, so that with
PROFIsafe V2, a 3 byte CRC is used.

The DFS21B option supports the following settings:

• F_CRC_Length = 3 byte CRC (only with PROFIsafe V2)

This parameter identifies the PROFIsafe version supported by the DFS21B option.

®

When using a MOVIDRIVE

B PROFINET variant, only PROFIsafe V2 is supported.

The PROFIsafe addresses are used for clear identification of the source
(F_Source_Add) and destination (F_Dest_Add). The combination of source and target
address must be unique across the network and all stations. The source address
F_Source_Add is automatically provided by STEP7 depending on the master configu­ration.

Values ranging from 1 to 65534 can be entered in parameter "F_Source_Add".
You cannot directly edit this parameter in STEP7 HW Config.

Values ranging from 1 to 1023 can be entered in parameter "F_Dest_Add".

This parameter defines a monitoring time in the DFS21B option.
A valid safety telegram must arrive from the F-CPU within this monitoring time. Other-

wise the DFS21B option reverts to safe status.
Select a monitoring time of a sufficient length so that communication can tolerate tele-

gram delays, but also sufficiently short enough for your safety application to run without
restriction.

With the DFS21B option, you can enter the "F_WD_Time" parameter in steps of 1 ms,
ranging from 1 ms to 10 s.

7.6 Data exchange with PROFIsafe option DFS

7.6.1 Introduction

The DFS option supports parallel operation of standard and safety-oriented communi­cation via fieldbus system or network. You can run safety-oriented PROFIsafe commu­nication using PROFIBUS DP (DFS11B) or PROFINET IO (DFS21B).

Data exchange between bus master and the DFS option takes place via the respective
communication system that simultaneously acts as a 'grey channel' for the safety-orient­ed application. The bus messages transferred then contain standard information for
conventional inverter operation and the PROFIsafe safety message. Depending on the
configuration, the maximum available expansion level enables parallel exchanges of
PROFIsafe safety data and the process data between the bus master and the DFS op­tion.

Data exchange with PROFIsafe option DFS

7.6.2 F periphery data block of the PROFIsafe option DFS

During compilation in the HW Config tool (HWCONFIG), the system automatically gen­erates an F periphery data block for every PROFIsafe option DFS. The F periphery data
block provides the user with an interface in which s/he can evaluate or control variables
in the safety program.

The symbolic name consists of the invariable prefix "F", the start address of the F pe­riphery, and the name entered in the object properties during configuration for the F pe­riphery (e.g. F00008_198).

The following table shows the F periphery data block of PROFIsafe option DFS.

Response times play a decisive role in the design and execution of safety functions of
systems and machines. In order to match the response time to the requirements of a
safety function, always take the entire system from sensor (or control device) to actuator
into account. The following times are decisive:

• Response times of the connected sensors

• Internal response time of the failsafe inputs (filter time + processing time)

• PROFIsafe cycle time

• Processing time (cycle time) in the safety controller

• PROFIsafe monitoring time "F_WD_Time"

• Internal reaction time of the safe outputs

• Response or switching time of the actuator

Error states of the PROFIsafe option DFS

7.9 Error states of the PROFIsafe option DFS

INFORMATION

Depending on the safety control used, other terms may be used for 'passivation' and
'reintegration' in the safety control documentation. For detailed information, refer to the
safety controller documentation.

7.9.1 Error in the safety module

PROFIsafe option DFS is able to detect various internal and external faults (at the fail­safe inputs/outputs). For information on the types of faults, exact responses, and how to
correct the faults, refer to the section entitled 'Fault table for PROFIsafe option DFS'.
When faults occur in the safety part, the DFS option usually responds by passivation of
the module and switching to substitute values instead of process values. All safety-ori­ented process values (F-DO) are then set to '0' (→ safe status).

After the fault has been corrected, the DFS option is reintegrated with a user acknowl­edgement.

7

7.9.2 PROFIsafe timeout

If safety-oriented PROFIsafe communication is interrupted or delayed, after the adjust­able monitoring time 'F_WD_Time' (see description of F parameters) has expired, the
DFS option also responds with passivation and assuming safe status. After this time has
expired, the relevant module is passivated in the safety control and the associated safe­ty-oriented process values for the safety application are set to '0' (→ safe status).

Whenever passivation occurs, user acknowledgement is required to reintegrate the
module in question.

It is also possible to set automatic reintegration in the safety controller.
Severe or fatal injuries.

• This function must not be used in safety-relevant applications.

Operating Behavior in Conjunction with PROFINET

Introduction

8 Operating Behavior in Conjunction with PROFINET

8.1 Introduction

Classic fieldbus communication is enhanced by fast Ethernet technology as a physical
transmission medium using PROFINET IO. PROFINET supports real-time capable pro­cess communication as well as open communication via Ethernet TCP/IP. PROFINET
distinguishes between three communication classes that differentiate in terms of effi­ciency and functionality.

Three communi­cation classes

Three unit types PROFINET IO differentiates between three unit types - 'IO controller', 'IO device' and 'IO

• TCP/IP

Open Ethernet TCP / IP communication without real-time requirements (e.g. web
technology)

• RT (Real-Time)

IO data exchange between automation units in real-time (>1 ms).

• IRT (Isochronous Real-Time)

Isochronous real-time communication for synchronized IO data exchange (e.g. for
motion control applications - not for DFE32B option).

The DFS21B option meets the requirements of the PROFINET RT class and provides
open communication via TCP/IP or UDP/IP.

supervisor'.

• IO controller

The IO controller undertakes the master function for the cyclic IO data exchange with
the decentralized field units and is usually implemented as a communication inter­face of a controller. It is similar to a PROFIBUS DP master class 1. A PROFINET IO
system can have several IO controllers.

• IO device

All field units of PROFINET IO that are controlled by an IO controller are designated
as IO devices, e.g. I/O, drives, valve terminals, etc. IO devices are comparable with
PROFIBUS DP slave nodes. The DFE32B option is a PROFINET IO device.

• IO supervisor

Programming devices / PC with corresponding engineering / diagnostic tools are
designated as IO supervisors. IO supervisors have access to process and parameter
data as well as alarm and diagnostic information.

Communication
model

Unit model The existing decentralized periphery of PROFIBUS DP has been enhanced for the de-

The communication model of PROFINET IO is based on the many years of experience
with PROFIBUS DP-V1. The master slave access procedure was mapped on a provid­er-consumer model.

Several communication channels are used for the data exchange between IO controller
and IO devices. The cyclic IO data and the event-driven alarms are transferred via real­time channels. The standard channel based on UDP / IP is used for parameter settings,
configuration and diagnostic information.

vice model. The device model is based on slot and subslot mechanisms where modular
devices with slots can be implemented for modules and submodules. In this way, the
slot and submodules are represented by subslots for the modules. These mechanisms
also enable logical modularization, e.g. for a drive system (→ following figure).

Operating Behavior in Conjunction with PROFINET

The integrated Ethernet switch

A single drive axle is represented as a module under PROFINET IO. Several submod­ules can be plugged into this module. The submodules determine the process data in­terface to the IO controller or the data traffic partner. Thus they have provider or con­sumer quality. The model provides the option to plug several modules into an IO device
for multi-axis systems that have a common PROFINET IO interface. In this way, each
module again represents a single axis. Slot 0 is used as a Device Access Point (DAP)
and usually represents the IO device.

8.2 The integrated Ethernet switch

You can use the integrated Ethernet switch to achieve line topologies known from the
fieldbus technology. Other bus topologies, such as star or tree, are also possible. Ring
topologies are not supported.

INFORMATION

The number of industrial Ethernet switches connected to the line affects the telegram
runtime. If a telegram passes through the units, the telegram runtime is delayed by the
store & forward function of the Ethernet switch:

• For a telegram length of 64 bytes by approximately 10 μs (at 100 Mbit/s)

• For a telegram length of 1500 bytes by approximately 130 μs (at 100 Mbit/s)
This means that the more units a telegram has to pass through, the higher the tele-

gram runtime is.

Auto-crossing The two ports leading out of the Ethernet switch have auto-crossing functionality. This

means that they can use both patch and cross-over cables to connect to the next Ether­net station.

Auto-negotiation The baud rate and the duplex mode are negotiated by both Ethernet nodes when estab-

lishing the connection. For this purpose, both Ethernet ports of the PROFINET connec­tion support an auto-negotiation functionality and work with a baud rate of either
100 Mbit or 10 Mbit in full duplex or half-duplex mode.

INFORMATION

PROFINET IO networks must be operated at a baud rate of 100 Mbit in full duplex
mode.

Monitoring the
LINK status

Both ports allow for a monitoring of the LINK status. You can set up this function via the
STEP 7 hardware configuration as follows:

• Select slot 0 in STEP 7.

• Select [Object properties] from the context menu.

• Select the tab "Parameters".
Only set the monitoring for the port that sends data packages to other nodes and not to

the control. If a LINK DOWN is detected when the monitoring function is switched on,
the PROFINET device sends a diagnostics alarm to the controller via the other port
(→ chapter "Alarms").

8.3 Process data configuration

For the DFS21B option, slot 1 must be configured as 'slot not used'. Modules with 1 to
10 I/O process data words can be configured in slot 2. After the unit is switched on and
before the IO controller establishes the communication, the configuration is set to 3 I/O
process data words. This can be changed by the IO controller while communication is
being established. The current configuration is displayed in P090 PD configuration.

The DAP (Device Access Point) is designated as ID 100 (slot 0, subslot 1)

INFORMATION

The configuration of the DFS21B option is compatible to the DFE12B option. That
means that you do not have to change the configuration when you replace the
DFE12B option with the DFS21B option. The DFS21B option then accepts 1 ... 10 pro­cess data words at slot 1.

drive inverters. The H1 LED (system bus fault) at the DFS is lit. The exact error code of
the gateway status can be displayed via the diagnostics interface with MOVITOOLS
MotionStudio (Tool "Status").

8.5.4 Fieldbus timeout response of the DFS21B in gateway operation

You can set how the gateway should respond in case of timeout using the P831 Fieldbus
timeout response parameter.

No response The drives on the subordinate SBus continue with the last setpoint value.

These drives cannot be controlled when the PROFIBUS communication is
interrupted.

The rapid stop is activated for all drives that have a process data configuration
with control word 1 or 2 when a PROFINET timeout is detected. For this, the
gateway sets the bits 0 to 2 of the control word to 0.
The drives are stopped via the rapid stop ramp.

PROFINET configuration with topology detection

8.8 PROFINET configuration with topology detection

8.8.1 Introduction

The PROFINET technology detection allows for projecting and monitoring the structure
of the network with the PROFINET IO controller in addition to the PROFINET IO devic­es.

The so-called 'Physical device (PHDEV)' is the starting point for the configuration. PDEV
is a model for the Ethernet interface and can be found in slot 0 in the configuration with
an 'Ethernet interface' subslot and one subslot for each Ethernet port.

The Ethernet ports made visible in this way can be connected to the configuration tool.
The result is an image of the desired Ethernet routing for the plant. This image is stored
in the PROFINET IO controller.

In order to be able to determine the real plant topology, the PROFINET IO devices must
support the so-called LLDP (Link Layer Discovery Protocol). The PROFINET IO devices
exchange information with the neighboring PROFINET IO devices via LLDP. Via LLDP,
each PROFINET IO device cyclically sends information on its own PROFINET device
name and port number. The neighboring unit receives and stores this information. Now
a PROFINET IO controller can read the stored information from the PROFINET IO de­vices, thus determining the real plant topology.

By comparing the projected topology with the real topology, you can detect any missing
or incorrectly wired PROFINET IO devices and localize them in the plant.

Apart from cabling you can still determine the transmission characteristics for the ports.
For example, you can set an 'Auto-negotiation' port to '100 Mbit full duplex'. The settings
will be monitored.

SNMP (Simple Network Management Protocol) as a protocol for network diagnostics
extends the topology detection with standard diagnostics mechanisms from the IT area.

PROFINET configuration with topology detection

The following section describes the the configuration procedure for a PROFINET topol­ogy with the SIMATIC STEP 7 topology editor. Configuration can be performed in differ­ent ways in SIMATIC STEP 7. This example will focus on one approach.

1. In STEP 7 HW Config, import the PROFINET devices from the hardware catalog into

the PROFINET network as usual.
Make sure that the PROFINET IO controller supports the topology detection. The

controller manufacturer will provide according information.
The hardware catalog contains several entries for each SEW interface marked as dif-

ferent versions. An entry marked with 'ALT' does not support the PROFINET IO to­pology detection.

2. Right-click on the 'PROFINET IO system' and select 'PROFINET IO topology' from

the context menu to start the topology editor.
The 'Topology editor' window is displayed.

3. Proceed according to section 'Specifying the topology and detecting faulty connec-

tions'.

PROFINET configuration with topology detection

8.8.3 Specifying the topology and detecting faulty connections

Topology detec­tion via topology
editor

The topology detection is to compare the current topology (online topology) with the con­figured topology (offline topology). Any deviations suggest faulty connections in the
PROFINET network.

The following section provides an introduction as to how to use the topology editor to
specify PROFINET nodes and detect faulty connections to ports.

Refer to the online help for a detailed description and important additional information
(e.g. the color code of the comparison results).

Click [Help] to open the online help in the open topology editor.

8.8.4 Changing the port properties

The two Ethernet ports of the PROFINET interface are set to 'Automatic setup' by de­fault. Observe the following for this default setup:

• Auto-negotiation and Auto-crossover are activated.

• The baud rate and the duplex mode are configured automatically.

• The neighboring port must also be set to 'Automatic setup'.

• You can use patch or crossover cables.

You may set a port to '100 Mbit/s full duplex'. Observe the following for this setup:

• This setting must also be made for the port of the neighboring unit, otherwise it would
work with 100 Mbit/s half duplex.

• If auto-crossover is deactivated, you have to use cross cables.

Proceed as follows to set a port to '100 Mbit/s full duplex':

1. Select a unit in STEP 7 HW Config.

2. Select the desired port on slot 0.

3. Right-click on the port and select 'Object properties' from the context menu.

try to reduce the utilization by especially reducing the number of broadcast and mul­ticast telegrams and reducing the IO cycle or the number of PROFINET units in a line
if required.

• Bad received packets
Shows the number of faulty Ethernet packets. A high number suggests a bus error.

In this case, check the cabling and shielding of the network.

• Received octets
Shows the number of received packets.

9.1 Introduction to PROFINET data records

With "Read Record" and "Write Record", PROFINET offers acyclic services that can be
used to transfer parameter data between PROFINET controller (master) and a
PROFINET device (slave). Via UDP (User Datagram Protocol), the priority of this data
exchange is lower than the priority of the process data exchange.

9

62204AXX

The user data transported via an acyclic PROFINET service is grouped in a dataset.
Each dataset is clearly addressed by the following characteristics:

• API

•Slot number

• Subslot number

• Index

The structure of dataset 47 is used for the parameter exchange with SEW-EURODRIVE
PROFINET units. The structure of dataset 47 is specified in the PROFIdrive profile drive
technology of the PROFIBUS user organization as of V4.0 as PROFINET parameter
channel. Different procedures for accessing parameter data of the SEW-EURODRIVE
PROFINET unit are provided via this parameter channel.

Introduction to PROFINET data records

9.1.1 Characteristics of the SEW-EURODRIVE PROFINET devices

The SEW-EURODRIVE PROFINET units that support acyclic Read Record and Write
Record services all have the same communication characteristics. The units are basi­cally controlled via a PROFINET controller with cyclic process data. Additionally, this
controller (usually a PLC) can set the parameters for the SEW-EURODRIVE PROFINET
unit via Read Record and Write Record.

Parameterization via PROFIdrive Data Set 47

Structure of the PROFINET parameter channel

9.2.1 Parameter setting procedure via data record 47

Parameters are accessed with the combination of the WRITE RECORD and READ
RECORD PROFINET services. The parameterization request is transferred to the IO

device using the WRITE.req, Then it is processed internally.
The controller now sends a READ.req to pick up the parameterization response. The de-

vice sends a positive response READ.res. The user data now contain the parameteriza­tion response of the parameterization request that was previously sent with WRITE.req
(see the following figure). This mechanism applies to a PROFINET controller.

9.2.2 Controller processing sequence

If the bus cycles are very short, the request for the parameterization response arrives
before the SEW device has concluded the parameter access in the device. This means
that the response data from the SEW device is not available yet. In this state, the device
delays the response to the Read Record Request.

Parameterization via PROFIdrive Data Set 47

Structure of the PROFINET parameter channel

9.2.5 PROFIdrive parameter requests

The PROFIdrive parameter channel of SEW inverters is directly mapped in the structure
of data set 47. Parameter access with PROFIdrive services usually takes place accord­ing to the structure described below. The typical telegram sequence is used for data set

47. PROFIdrive only defines the two request IDs

Request ID: 0x01request parameter (PROFIdrive)
Request ID: 0x02change parameter (PROFIdrive)

This means there is restricted data access in comparison with the MOVILINK

INFORMATION

The request ID 0x02 Change Parameter (PROFIdrive) results in remanent write ac­cess to the selected parameter. Consequently, the internal flash/EEPROM of the in­verter is written with each write access. Use the MOVILINK
eter volatile' if parameters must be written cyclically at short intervals. With this ser­vice, you only alter the parameter values in the RAM of the inverter.
