2.3 DeviceNet Introduction

DeviceNet is an open system based on CAN, developed by Bosch a few years ago. CAN was primarily
intended for the transfer of data within automobiles, and millions on CAN Chips have since been installed.
The disadvantage of using CAN in automation technology is that it does not define an application layer. It
specifies only the physical layer and data security layer.

DeviceNet specifies a uniform application layer and this makes it possible to use the CAN protocol for
industrial applications. ODVA (the open DeviceNet Vendor Association) is an independent association
which supports Manufactures and users of the DeviceNet system. ODVA ensures that all of the devices
which conform to the specification can operate together in one system, regardless of their manufacturer.

Example of DeviceNet in use:

For more details see the DeviceNet Specification or look at www.odva.org, the official Internet address of
the Open DeviceNet Vendor Association (ODVA).

3 Fitting and Wiring

3.1 Installation

3.1.1 FC520x

Note:

Fieldbus PCI cards may only be fitted by qualified personnel in accordance and the following points

must be observed

•

In order to protect the card from electrostatic discharge the user must be discharged before han-

dling the card or the PC.

•

Before opening the PC housing it must be switched off, and the mains plug must be removed.

Channel B

14

A

It may be necessary before fitting to set the Dip-Switch in order to activate the internal CAN / DeviceNet
bus terminating resistors. The card can be fitted into any free PCI slot. Ensure that the PCI bus connector
is making good contact, and that the module is seated firmly. Fasten the module to the PC slot housing
with the fixing screw.

3.2 Wiring the Bus System

3.2.1 CAN / DeviceNet topology

CAN / DeviceNet is a 2-wire bus system, to which all participating devices are connected in parallel (i.e.
using short drop lines). The bus must be terminated at each end with a 120 (or 121) Ohm terminating
resistor to prevent reflections. This is also necessary even if the cable lengths are very short!

Since the CAN signals are represented on the bus as the difference between the two levels, the CAN
leads are not very sensitive to incoming interference (EMI): Both leads are affected, so the interference
has very little effect on the difference.

16

3.2.2 Bus Length

The maximum length of a CAN bus is primarily limited by the signal transit time. The multi-master bus
access procedure (arbitration) requires signals to reach all the nodes at effectively the same time (before
the sampling within a bit period). Since the signal transit times in the CAN connecting equipment (trans­ceivers, opto-couplers, CAN controllers) are almost constant, the line length must be chosen in accor­dance with the baud rate:

For the DeviceNet use of the CAN Bus following Baud Rates and Bus Lengths are specified:

BaudRate

500 kbit/s
250 kbit/s
125 kbit/s

Bus Length

< 100 m
< 250 m
< 500 m

3.2.3 Drop-Lines

Drop lines must always be avoided as far as possible, since they inevitably cause reflections. The reflec­tions caused by drop lines are not however usually critical, provided they have decayed fully before the
sampling time. In the case of the bit timing settings selected in the bus couplers it can be assumed that
this is the case, provided the following drop line lengths are not exceeded (according to DeviceNet Speci­fication):

BaudRate Drop line length Total length of all drop lines

500 kbit/s
250 kbit/s
125 kbit/s

< 6 m
< 6 m
< 6 m

< 39 m
< 78 m
< 156 m

Drop lines must not have terminating resistors.

Star Hub (Multiport Tap)

Shorter drop line lengths must be maintained with passive distributors ("multiport taps"), such as the
Beckhoff ZS5052-4500 Distributor Box. The following table indicates the maximum drop line lengths and
the maximum length of the trunk line (without the drop lines):

Note: These values are recommended by Beckhoff

BaudRate Drop line length with multi-

port topology

500 kbit/s
250 kbit/s
125 kbit/s

< 1,2 m
< 2,4 m
< 4.8 m

Trunk line length (without drop
lines)

< 66 m
< 120 m
< 310 m

4 Parameterisation and Commissioning

4.1 Configuration: TwinCAT System Manager

The TwinCAT System Manager Tool is used to configure the FC520x DeviceNet PCI card and the
CX1500-x520 Fieldbus Modules. The System Manager provides a representation of the number of pro­grams of the TwinCat PLC systems, the configuration of the axis control and of the connected I/O chan­nels as a structure, and organises the mapping of the data traffic.

For applications without TwinCAT PLC or NC, the TwinCAT System Manager Tool configures the pro­gramming interfaces for a wide range of application programs:

•

ActiveX control (ADS-OCX) for e.g. Visual Basic, Visual C++, Delphi, etc.

•

DLL interface (ADS-DLL) for e.g. Visual C++ projects

•

Script interface (ADS script DLL) for e.g. VBScript, JScript, etc.

4.1.1 System Manager – Features

•

- Bit-wise association of server process images and I/O channels

•

- Standard data formats such as arrays and structures

•

- User defined data formats

•

- Continuous variable linking

•

- Drag and Drop

•

- Import and export at all levels

4.1.2 Configuration by means of the TwinCAT System Manager

The procedure, and the configuration facilities in the System Manager are described within the next chap­ters.

4.2 DeviceNet Device

4.2.1 Append Device

Appending a Device can either be executed by running the “Scan-Devices” routine of the TwinCAT Sys­tem Manager or by selecting manually the Device out of the list of possible DeviceNet Devices.

Appending the Device manually is done by e.g. selecting the “IO-Devices” and apply the right Mouse­Button:

4.2.1.1 Apend the FC520x as DeviceNet Slave

If the FC520x-Device is appended manually, all settings for the DeviceNet Slave are configured automati­cally.

If the FC520x-Device is appended with the “Scan-Devices” routine, TwinCAT should not search for new
Boxes. The scan has to be stopped after detecting the FC520x and the following steps have to be done:

1. Switch the DeviceNet-Mode to “Slave”

2. Append Box for FC520x DeviceNet Slave Port

4.4.2 Configuration

4.4.2.1 BK52x0 / IX-B52x / DeviceNet Node
BK52x0 / IX-B52x

32

MAC Id

: Sets the MAC-ID of the DeviceNet participant (between 0 and 63). This value must comply with

the value set at the Bus Coupler.

Cycle Time

: Sets the cycle time for the I0 connection (Polled and Bit-Strobe). This value is added to the
Expected Packet Rate (EPR) attributes of the DeviceNet slave and acts as a timeout monitor for IO con­nections.

Electronic Key

: Serves to check the devices within the network at the system StartUp. The electronic

key is read from the devices at every system StartUp and compared with the saved configuration.

Polled

: Produced/Consumed: Activation of the ”Polling” operating mode, cyclical writing and reading of IO
data. Setting of the data content of the data transmitted via the polled IO connections. You can choose
from digital data, analogue data or both. The selection depends upon the BK52xx terminal arrangement.

Bit-Strobed

: Produced/Consumed: Activation of the ”Bit Strobe” Operating Mode. With a broadcast mes­sage all nodes are requested to send their bit strobe message (up to 7 bytes input or status data). Setting
of the data content of the data transmitted via the bit-strobed IO connections. You can choose between
digital data or diagnostic data.

Change of State / Cyclic

:

- Produced/Consumed: Setting of the data content of the data transmitted via the change of state/cyclical
IO connections. You can choose from digital data, analogue data or both. The selection depends upon
the BK52xx terminal arrangement.

- Change of State / Cyclic: Selecting the Corresponding Operating Mode

- Heartbeat Rate / Scan Rate: In the "Change of State" mode the heartbeat rate gives the cycle time of
the cyclical send of the lower-level (i.e. in addition to the event driven) IO data. In the ”Cyclic” operating
mode the scan rate gives the cycle time of the IO data send.
Inhibit time: Delay period in the ”Change of State” operating mode inserts this pre-set delay period after a
change of state before the IO data send.
Acknowledge Timeout: Time before the re-send in the event of faulty acknowledgement of a change of
state / cyclical message.
Acknowledge Retry Limit: Maximum number of re-sends until IO connection goes into error mode.

K-Bus Update

: Calculates the anticipated duration of a complete update of the terminal bus (according to
the number of connected terminals). This is not to be seen as the response time of the DeviceNet Node
to DeviceNet IO-Requests.

Auto Device Replacement (ADR)

Attributes/Parameters sent to the Box at StartUp of the Network are displayed/managed on this page.
Other entries can be managed using ”New”, ”Delete” and ”Edit”:

Start-Up Attributes are loaded into the DeviceNet Box at the Beginning of each Network-Startup.. The
values are loaded before the IO-Connections are started.

4.4.2.3 ADS

In order to be able to read and write attributes during the running time (e.g. from the PLC), the Box (e.g.
Bus Coupler) can be allocated via an ADS port. The ADS Port can be used to read / write attributes via
ADS read requests / ADS write requests:

The ADS IndexGroup contains the ClassId and the ADS IndexOffset contains InstanceId and AttributeId
(InstanceId * 256 + AttributeId).

The following ADS-Commands are used to exchange DeviceNet Explicit-Messages:

ADS Command

ADSRead Get_Attribute_Single (0x0E) ClassId (InstanceId * 256 + AttributeId)
ADSWrite Set_Attribute_Single (0x10) ClassId (InstanceId * 256 + AttributeId)

4.4.2.4 Parameter

The parameters are read from the EDS-File when appending the box. If the system has not started up,
the EDS default value is always displayed under the value input:

When configuring a DeviceNet node, an electronic data sheet (EDS) is usually provided by the manufac­ture of that device to assist in this task. An EDS file is a text file that describes properties of a particular
DeviceNet node. It includes the number of bytes that are transmitted to the node (output information) and
the number of bytes that are received from the node (input and status information). Furthermore it in­cludes a Parameter sections, which is analyzed by the SystemManger and displayed within this section.
