2 Safety instructions

Please observe the following safety instructions when you want to commission a controller
or system using the Industrial PC.

 Read the documentation supplied with the system components thoroughly before

starting to commission the devices and the Industrial PC!

The system manual contains safety instructions which must be observed!

 Danger!

According to our present level of knowledge it is not possible to ensure the abso­lute freedom from errors of a software.

If necessary, systems with built-in controllers must be provided with additional
monitoring and protective equipment according to relevant safety regulations
(e.g. law on technical equipment, regulations for the prevention of accidents) so
that an impermissible operating status does not endanger persons or facilities.

Control technology| System manual

Safety instructions

During commissioning, persons must keep a safe distance from the motor or the
machine parts driven by the motor. Otherwise there would be a risk of injury by
the moving machine parts.

 Stop!

If you change parameters in an engineering tool during an existing online con­nection to a device, the changes are directly added to the device!

A wrong parameter setting can cause unpredictable motor movements. By unin­tentional direction of rotation, too high speed or jerky operation, the driven ma­chine parts may be damaged!

The "PC-based Automation" system

3 The "PC-based Automation" system

Industrial PCs (IPCs) become more and more important in the field of automation techno­logy. Due to their scaling options and various combinations of visualisation and control on
one device, Industrial PCs provide clear advantages for many applications.

Lenze Industrial PCs are available with the following software equipment:

 Industrial PC as component, on request with operating system, without further softwa-

re

 Industrial PC as visualisation system

 Industrial PC as control and visualisation system

The "PC-based Automation" system enables the central control of logic and motion sys­tems.

For this purpose, Lenze provides coordinated system components:

 Industrial PCs as control and visualisation system

– The IPC is the central component of the PC-based automation which controls the lo-

gic and motion functions by means of the runtime software.
– The IPC communicates with the field devices via the fieldbus.
– The IPCs are available in different designs.

 Note!

Moreover, the "PC based automation" system comprises the HMI series
EL 1xx PLC. These devices differ considerably from the Industrial PCs with regard
to performance and various other details. However, the devices of the HMI series
EL 1xx PLC are able to perform smaller control functions.

This chapter describes the basic structure of a control system based on an Industrial PC and
the required components.

4.1 System components

4.1.1 The Industrial PC

4.1.1.1 IPC types

Thanks to a consequently implemented platform strategy, Industrial PCs can be assembled
individually and are nearly optionally scalable with regard to power, display size, and func­tion. This results in three different designs from which you can select the tailor-made plat­form for the prevailing automation solution.

This universal and scalable IPC platform is complemented by HMIs which are provided in
fixed configurations and can also fulfil automation functions in a restricted way.

The following designs are distinguished:

The runtime software comprises the operating system. Moreover, further software compo­nents are required which, for example, execute the control program.

Control technology| System manual

System description

System components

The Industrial PCs are supplied completely with the runtime software. The different com­ponents of the runtime software are described in the following.

 L-force Logic

The L-force Logic runtime software is a soft PLC. It serves to execute PLC programs which
have been created with the »PLC Designer« . These programs describe logic operations.
L-force Motion

The programs are processed cyclically by a multitasking operating system. L-force Logic
merely describes the function; the performance of the control system results from the in­teraction of the runtime software with the selected target system and thus directly de­pends on the selected processor and other factors.

L-force Logic is available for the following target platforms:

Industrial PCs:

– Embedded Line EL 1800-9800
– Command Station CS 5800-9800
– Control Cabinet CPC 2800

HMIs:

– EL100 PLC

( 20) serves to control drive-related processes.

 L-force Motion

In contrast to L-force Logic, L-force Motion serves to trigger controllers in addition to pro­cessing PLC programs.
In addition to all functions of the L-force Logic, also Soft Motion functions are supported
according to PLCopen part I and II.

L-force Motion is available for the following target platforms:

Industrial PCs:

– Embedded Line EL 1800-9800
– Command Station CS 5800-9800
– Control Cabinet CPC 2800

 L-force Visu

The L-force Visu runtime software serves to extend your IPC to a visualisation device. The
visualisation can be installed on a separate IPC but can also run on the same IPC in parallel
to the control. There are different options for the communication interface connection.

The resulting four options and their advantages and disadvantages are described in the fol­lowing.

L-force Visu is available for the following target platforms:

Industrial PC as gateway

If it is required to separate control and visualisation, e.g. for performance reasons or due to
different operating systems, the control IPC can be used as gateway. The visualisation IPC
does not require any special fieldbus connection, only the Ethernet interface available as
standard is required. The implementation from Ethernet to the fieldbus is executed by the
Industrial PC.

Properties:

– Visualisation has access to variables of the control and parameters of the field de-

vices
– No impact on the real-time capability of the bus by the visualisation
– Several visualisations can access the same control
– Optimal for graphically complex visualisations
– Not available for HMI series EL100

Independent control and visualisation

In this variant, the control and visualisation access the bus independently of each other.
This ensures the most possible independence of both systems but is only very rarely sen­sible in practice.

 Note!

The configuration with control and visualisation that are independent of each
other is only recommended for systems without Lenze control!

Properties:

– Visualisation has access to parameters of the field devices
– Impact on the real-time capability of the bus by the visualisation is possible, thus it

is only suitable in Motion systems in a restricted way (also depending on the bus sys-

tem used)
– Depending on the prevailing bus system, several bus masters can be used which are

independent of each other:
–Use of CANopen
– In connection with EtherCAT a configuration with two bus masters is not possible.
– Available for HMI EL100

4.1.4 Backup

Industrial PCs do not have hard disks as data memories. The operating system is saved on
memory chips. Depending on the series, this memory chip can either be permanently inte­grated or implemented using a memory card.

The following Industrial PC series use a
Compact Flash card (CF card) as storage medium:

 EL 1800 - EL 9800,

 CS 5800 - CS 9800,

 CPC 2800.

The Compact Flash card is the "memory" of the IPC. Without this CF card, the IPC cannot
run.
»IPC Backup & Restore« serves to copy, duplicate, and archive these cards. To transfer user­specific data from the Industrial PC to an Engineering PC and vice versa, USB flash drives
can be used.

Network topologies

4.2 Network topologies

The Lenze control technology provides master interface connections for the following com­munication systems:

 CANopen: Tried-and-tested system for smaller plants

 EtherCAT: Ethernet-based system for every application
 PROFIBUS: For the greatest selection of different field devices

Lenze's control technology is based on CANopen profiles. The communication system sup­ported by the respective application is used for data transfer.

 Tip!

The Lenze support assists you in selecting the fieldbus system tailored for your ap­plication and the suitable Industrial PC components.

Depending on the bus system used, the basic structure of the network varies. The bus sys­tem also influences the usability of the different device families. This is described in the fol­lowing:

32 L DMS 1.3 EN - 02/2011

4.2.1 Control technology with CANopen

CANopen as the basis for the Lenze control technology

 The control technology based on CANopen serves to implement the classical Lenze de-

vice series that have the system bus (CAN) on board. Thus, solutions at optimal cost are
possible.

 In order to extend the existing limits of the CAN bus, up to four CAN lines can be used

which are synchronised among each other.

 The highest possible number of nodes on a CAN line depends on the baud rate and the

set cycle time.
– Example: Three nodes can be connected to the CAN bus with a setpoint PDO and an

actual value PDO each at a cycle time of 1 [ms] and a baud rate of 1[MBit/s].

Control technology| System manual

System description

Network topologies

Physical structure

Due to the real time requirements of the bus system and the limited transmission capacity,
it is vital with CANopen to separate the bus line with Motion from the one with compon­ents that are controlled via PLC functionalities only (Logic). Moreover it is required, depen­ding on the number of Motion nodes and the bus cycle time, to create several Motion bus
lines.

CANopen uses separate CAN interfaces to operate Logic and Motion nodes:

 The IPCs support up to four CAN interfaces.

– Interface 1 is CANOpen(Logic),
– Interface 2-4 is CANOpen(Motion).
– If no Logic is required, the interface 1 can additionally be Motion. Thus, up to four

synchronised Motion buses are possible.

 Note!

• When the IPC type "Command Station" is used, only two bus lines are possib­le!

• Depending on the required number of Motion nodes and bus cycle time, up
to four Motion bus lines can be created.

• When the IPC series "Command Station" CS x8xx is used, only two bus lines
are possible.

Convention for "PC based Automation"

• Bus line 1 (CAN1): CANopen (Logic) or CANopen (Motion)

• Bus line 2 - 4 (CAN2 - 4): CANopen (Motion)

4.2.2 EtherCAT

 Note!

EtherCAT is a very powerful bus system which is based on Ethernet.

 EtherCAT is suitable for greater applications

 The highest possible number of nodes at an EtherCAT line mainly depends on the per-

formance of the Industrial PC due to the great bandwidth of this bus system.
– Depending on the Industrial PC used and the required computing time of the appli-

cations which run on the IPC (PLC and optional visualisation), a high number of nodes
at a low cycle time is possible.

System description

Network topologies

EtherCAT is not available for Industrial PCs of the device series EL 1xx, EL x8xx,

Physical structure

Thanks to the integrated synchronisation mechanisms via "distributed clocks", EtherCAT
offers excellent real-time features. Thus, Motion and PLC applications can be operated via
the same bus and the number of the nodes to be controlled and the maximum bus length
is much higher compared to a CANopen system.

 EtherCAT can control all field devices at one common interface. Thus, no division into

Logic fieldbus and Motionbus is required.

modern bus systems. Due to the low bandwidth and synchronisation mechanisms, the
PROFIBUS is only provided as logic bus within the "PC-based Automation".

We recommend to use the PROFIBUS for the following applications:

To commission the control system, an Engineering PC is required. This can be a standard
laptop. Here, the programs are installed which are required for configuration, parameter
setting, and commissioning of the control system. The programs are listed in chapter 3.2.3.

The Engineering PC which is connected with the Industrial PC via Ethernet, serves to install
the control system. For the operation of the control and visualisation system, the Enginee­ring PC is not required anymore.

An Engineering PC can be used for the configuration of any number of Industrial PCs.

IPC as gateway

6.1 IPC as gateway

The Engineering PC is not only required for commissioning the Industrial PC but also for
commissioning the subordinated field devices. To establish an online connection between
an Engineering PC and a field device, e.g. a controller, two ways are possible:

Direct coupling

IPC as gateway ( 45)

6.1.1 Direct coupling

In case of direct coupling, the Engineering PC has a special interface module for the corre­sponding fieldbus, e.g. a USB system bus adapter for coupling to the CANopen bus system.

Advantage:

The connection of the Engineering PC to the drive is totally independent from the control.
Thus, it is irrelevant whether the control is already available in the system, or already com­missioned, etc.

The speed at data transmission is optimal with direct coupling. The IPCs are used as gate­way, this optimal speed cannot be achieved.

( 44)

Disadvantage:

A special interface connection is required for the Engineering PC

The communication of the Engineering PC with the field device may interfere with the bus.
It is, for instance, possible that the real-time capability of the control is disturbed by the En­gineering PC since the Engineering PC overloads the bus or transmits telegrams at times
the control needs for transmission of synchronisation protocols.

44 L DMS 1.3 EN - 02/2011

6.1.2 IPC as gateway

In the second case, the Engineering PC is not provided with a special fieldbus coupling. Only
the Ethernet interface available as standard is required. The implementation from Ether­net to the fieldbus is made via the Industrial PC.

Control technology| System manual

System architecture

IPC as gateway

 Note!

• The "IPC as gateway" function is not available in combination with PROFIBUS.

• Thus, "Going online" with the »Engineer« or the »GDC« via the IPC as gateway
is not possible.

Advantage:

The Engineering PC does not require a special interface connection

The Engineering PC is the only master for the bus and can thus guarantee the real-time ca­pability of the bus since it controls the access to the bus itself. Thus, it is ensured that the
bus is always free for the control if required.

Disadvantage:

The gateway can only be used if the basic configuration of the IPC and the bus has been
carried out.

The communication speed for a download to a field device using the Engineering PC is slo­wer than with direct coupling. The extent of delay depends on whether the control is active
itself at this moment or only the gateway of the IPC is used.

Conclusion

Direct coupling is an appropriate means to commission field devices for the first time
(download). The download times are optimal and it is not required that the control has to
run.

DMS 1.3 EN - 02/2011 L 45

Control technology| System manual

System architecture
Function blocks

As soon as the control has been commissioned, no direct coupling should be used anymore
since, depending on the bus system, the real-time capacity of the bus may be disturbed.

6.2 Function blocks

A number of available function blocks offers the opportunity to access parameters of the
Industrial PC from the PLC program. These are the following:

 Device parameters of the Industrial PC,

 Device parameters of the field devices,
 Logbook entries of the Industrial PC.

7 Remote maintenance and diagnostics

In the PC technology, there are various standard mechanisms for remote connections bet­ween the nodes.

 The standard mechanisms

– are based on the Ethernet bus system or the protocols used for Ethernet.
– can be used between Engineering/remote maintenance PC and IPC.

It is irrelevant whether a local connection or a remote connection exists between Enginee­ring/remote maintenance PC and IPC.

 All access mechanisms described in the following can be used

– with direct coupling between the PCs within a local network,
– with a remote connection.

To establish a remote connection, a router is required. A router can be a separate device or
the IPC itself. A router establishes a remote connection between two network segments.

Remote maintenance and diagnostics

Typically, routers are used for the following connection types:

 Analog phone (modem),
 ISDN,

 DSL.

The client/server connection between the Engineering PC and Industrial PC is characteris­tical for a remote maintenance.
A server runs on the device to be accessed from afar. The server waits for a client to give a
signal from afar and want to access the PC. Depending on the action you want to carry out
from afar, different server types are available.

When a remote connection has been established once, you can work with the same pro­grams that are used for the local connection via Ethernet, as for example L-force »Engi­neer« or web server. Moreover, programs exist which are especially suitable for accessing
parts of the IPC. You can even redirect the complete screen content of the IPC so that you
can remote control it. The different programs available are described briefly in the follo­wing.

Dial-in on the IPC

 Note!

Setting a remote maintenance is a potential safety risk! This is particularly rele­vant if the computer to be remote-controlled is connected to an Ethernet net­work. Always contact your IT administrator to take the necessary safety
measures.

7.1 Dial-in on the IPC

An RAS server runs on the IPC. A user can log-in via modem/ISDN card on this RAS server. If
someone dials-in from a remote maintenance PC via this medium, the IPC executes a pass­word check and then activates the connection.

 Further information about the function and configuration of RAS servers can be

found in the following documentations:

• Industrial PC - parameter setting & configuration

• HMI EL 100 with Windows® CE

7.2 Computer access via Telnet

 Note!

Telnet is a standard mechanism reserved for experienced users to change sys­tem settings.

The Telnet protocol serves to access the data of a PC. Telnet requires an existing local con­nection or remote connection. Telnet is a command line-oriented protocol.

7.3 File transfer via FTP

To transfer files from one PC to another, FTP is frequently used. FTP is the abbreviation for
File Transfer Protocol.

 FTP requires an existing local connection or remote connection.

 FTP can be used via the command line, similar to Telnet.

Many programs have an integrated FTP support as for example the Internet Explorer.

 Further information about the function and configuration of FTP can be found in

the following documentations:

• Industrial PC - parameter setting & configuration

• HMI EL 100 with Windows® CE

48 L DMS 1.3 EN - 02/2011

7.4 Web server

If the PC has a web server, the user is provided with ready-made views which can be dis­played via a browser as the Internet Explorer. Depending on the structure of these web pa­ges, they may allow the change of parameters. Calling a web server requires an existing
local connection or remote connection.

All Lenze IPCs which support the control technology have an integrated web server. The
web server allows for a web-based parameter setting.

Redirecting screen contents/entries

7.5 Redirecting screen contents/entries

Comfortable programs for remote maintenance allow for a complete redirection of the en­tire screen contents. Moreover, all keyboard entries or mouse movements are transmitted
from the local PC to the remote PC. Thus you can operate the remote PC as if you would be
directly in front of it. However, the quality of the remote connection is decisive as the speed
of the presentation of the screen contents depends strongly on it. A bad connection may
render the operation of a program using the mouse impossible since you cannot track the
movements of the mouse pointer. In such cases, you can use the command line-based pro­tocols as FTP and Telnet, depending on the function to be executed.

The use of a screen redirection requires an existing local connection or remote connection.
For redirecting the screen contents, the following programs are available, depending on
the device type:

 EL100:

– VNC (see manual EL100)

 EL 1800-9800, CS 5800-9800, CPC 2800:

– Cerdisp/Cerhost

7.5.1 Virtual Network Computing (VNC)

Virtual Network Computing (VNC) is a software developed by Olivetti & Oracle Research
Laboratory (from 1999 AT&T), which shows the screen content of a remote computer (with
the VNC server software running) on a local computer (with the VNC viewer software run-

7.5.2 Cerdisp/Cerhost

ning) and transmits the keyboard and mouse movements from the local computer to the
remote computer. Alternatively, an "only read" mode is possible, where local entries have
no impact on the remote computer.

VNC has an open source licence which means that the source code is free of charge for in­terested developers so that further developments are allowed. Thus, various VNC versions
are available in the internet.

The VNC server is already installed in the devices of the HMI series EL100 by default. The
Engineering PC requires the VNC viewer software. It can be downloaded from the down­load area of the Lenze homepage AKB and is enclosed to the CD which is supplied with the
devices.

Microsoft provides the software combination Cerdisp/Cerhost for redirecting screen con­tents and keyboard and mouse entries.

 The Cerdisp is installed on the Industrial PC. The IPCs of the

EL 1800 series are supplied completely installed.

8 Appendix

This chapter informs you about the basics of the OPC communication standard and gives
you an overview of where OPC is used in the Lenze control technology.

8.1 Basics of the OPC standard

The industrial operation in the automation technology can be divided into three levels:

Control technology| System manual

Appendix

Basics of the OPC standard

1. The master level manages and visualises information.

2. The control level manages information and serves as process control.

3. The field level manages data and provides measured values.

The control and master level mostly use PC components. The field level consists of hard­ware in the form of sensors and actors.

PC-based automation solutions are used to implement a suitable process connection to en­able the access to the data of the field level. To exchange data with PC applications, a spe­cial driver is required with a conventional automation solution. Each hardware requires its
own driver. Thus, the corresponding software application should be adapted to each hard­ware. The OPC standard simplifies the communication between Engineering PC and Indus­trial PC and the access to the data of the field level.

8.1.1 Communication by means of OPC

OPC is a standardised software interface for manufacturer-independent communication
in the automation technology. OPC stands for Openness, Productivity, Collaboration, for­merly OLE for Process Control. The target is to exchange data between different software
applications.

Control technology| System manual

Appendix
Basics of the OPC standard

8.1.2 OPC as universal driver

The OPC-Data Access specification provides a universal driver for the automation techno­logy. The universal driver encapsulates the original driver and provides the generally un­derstandable services via a universal interface. The application of the automation
technology comes across a uniform interface when accessing the data on the field level.

8.1.3 OPC items

The process variables are represented by items when an OPC server is used. Thus, an item
is the transport medium of a variable. Since in the most cases, only a part of the items pro­vided by the OPC server is of interest for the client, they can be summarised in groups. "dif­ferent

In addition to the contents of the variables, an item contains various additional informati­on for the data. This additional information is called metadata.

An item is assigned to the following metadata:

 Item definition: Unambiguous string of digits to identify an item

 Access rights: Access authorisation to the item (reading, writing, or both)
 Canonical data type: original data type as in the field device

 Time stamp: Time of the last change of an item

 OPC quality: State of an item, references to communication errors

An OPC client either receives the values of the items from the PLC or from the item cache
of the OPC server.

52 L DMS 1.3 EN - 02/2011

8.1.4 OPC tunnel

If an OPC server and an OPC client are located on different computers, OPC tunnels are
used. This is a software which is installed on both computers and acts as client and server
itself. The data is transferred between the OPC server and OPC client by the OPC tunnel via
the TCP/IP protocol. Thus, OPC tunnels provide a platform and network-spanning commu­nication of OPC-based applications. This serves to avoid the "conventional" communicati­on of distributed client/server applications via DCOM.

Control technology| System manual

Appendix

Basics of the OPC standard

OPC tunnels are mainly used to connect the Engineering PC with the Industrial PC. Howe­ver they can also be used in connections between the Industrial PC and other computers.
