Safety Notes!
Before starting the installation
„ Disconnect the power supply of the device.
„ Ensure that devices cannot be accidentally restarted.
„ Verify isolation from the supply.
„ Earth and short circuit.
„ Cover or enclose neighboring units that are live.
„ Follow the engineering instructions (AWA) of the device
concerned.
„ Only suitably qualified personnel in accordance with EN 50 1101/-2 (VDE 0 105 Part 100) may work on this device/system.
„ Before installation and before touching the device ensure that
you are free of electrostatic charge.
„ The functional earth (FE) must be connected to the protective
earth (PE) or to the potential equalization. The system installer is
responsible for implementing this connection.
„ Connecting cables and signal lines should be installed so that
inductive or capacitive interference do not impair the automation
functions.
„ Install automation devices and related operating elements in
such a way that they are well protected against unintentional
operation.
„ Suitable safety hardware and software measures should be
implemented for the I/O interface so that a line or wire breakage
on the signal side does not result in undefined states in the automation devices.
„ Ensure a reliable electrical isolation of the low voltage for the 24
volt supply. Only use power supply units complying with IEC 60
364-4-41 (VDE 0 100 Part 410) or HD 384.4.41 S2.
„ Deviations of the mains voltage from the rated value must not
exceed the tolerance limits given in the specifications, otherwise
this may cause malfunction and dangerous operation.
„ Emergency stop devices complying with IEC/EN 60 204-1 must
be effective in all operating modes of the automation devices.
Unlatching the emergency-stop devices must not cause restart.
I
„ Devices that are designed for mounting in housings or control
cabinets must only be operated and controlled after they have
been installed with the housing closed. Desktop or portable units
must only be operated and controlled in enclosed housings.
„ Measures should be taken to ensure the proper restart of
programs interrupted after a voltage dip or failure. This should
not cause dangerous operating states even for a short time. If
necessary, emergency-stop devices should be implemented.
„ Wherever faults in the automation system may cause damage to
persons or property, external measures must be implemented to
ensure a safe operating state in the event of a fault or malfunction (for example, by means of separate limit switches, mechanical interlocks etc.).
„ The electrical installation must be carried out in accordance with
the relevant regulations (e. g. with regard to cable cross
sections, fuses, PE).
„ All work relating to transport, installation, commissioning and
maintenance must only be carried out by qualified personnel.
(IEC 60 364 and HD 384 and national work safety regulations).
„ All shrouds and doors must be kept closed during operation.

BL67 - Philosophy
The Basic Concept
BL67 is a modular IP67 I/O system for use in industrial automation.
It connects the sensors and actuators in the field to the higher-level
controller.
BL67 offers modules for practically all applications:
„ Digital input and output modules
„ Analog input and output modules
„ Technology modules (RS232 interface,...)
A complete BL67 station counts as one station on the bus and
therefore occupies one fieldbus address in any given fieldbus structure. A BL67 station consists of a gateway, power distribution
modules and I/O modules.
The connection to the relevant fieldbus is made via the bus-specific
gateway, which is responsible for the communication between the
BL67 station and the other fieldbus stations.
The communication within the BL67 station between the gateway
and the individual BL67 modules is regulated via an internal module
bus.
Note
The gateway is the only fieldbus-dependent module on a BL67
station. All other BL67 modules are not dependent on the fieldbus
used.

D301006 0806 - BL67 CANopen
The Basic Concept
Flexibility
1
A BL67 station can contain modules in any combination, which
means it is possible to adapt the system to practically all applications in automated industry.
Convenient Handling
All BL67 modules, with the exception of the gateway, consist of a
base module and an electronic module.
The gateway and the base modules are snapped onto a mounting
rail or are directly mounted onto a mounting plate. The electronic
modules are plugged onto the appropriate base modules.
After disconnection of the load, the electronic modules can be
plugged or pulled when the station is being commissioned or for
maintenance purposes, without having to disconnect the field wiring
from the base modules.

Electronic modules contain the functions of the BL67 modules
(power feeding modules, digital and analog input/output modules,
technology modules).
Electronic modules are plugged onto the base modules and are not
directly connected to the wiring. They can be plugged or pulled
when the station is being commissioned or for maintenance
purposes, without having to disconnect the field wiring from the
base modules.
Figure 3:

Power Feeding Modules
Power Feeding modules distribute the required 24 V DC field voltage
to the I/O modules. They are necessary for building groups of
modules with different potentials within a BL67 station, or if the
rated supply voltage for the outputs cannot be guaranteed.
Power Feeding modules are potentially isolated from the gateway,
the adjoining power supply module and the I/O modules to the left
side.
Note
For detailed information about the individual BL67 I/O components,
please refer to the chapters 2 to 8 of the manual "BL67- I/O modules" (TURCK Documentation-No.: German D300572; English:
D300529).
The "Appendix" to the manual mentioned above contains (amongst
others) a list of all BL67 components and the assignment of electronic modules to base modules.

Short description of CANopen
CANopen
Note
The following description of CANopen is an excerpt from the homepage of CiA (CAN in Automation), the international users’ and manufacturers’ organization for CAN.
General
CANopen is an open, non-proprietary network protocol. It consists
of a profile family, based on a communication profile and several
device profiles. The CANopen communication profile is standardized as CiA DS-301 (Application Layer and Communication Profile).
The CANopen device profile for I/O-modules has been published as
CiA DS-401 (Device Profile for I/O-Modules).
CANopen is based on the following standards:
„ ISO 11 898 (Physical and Data Link Layer)
„ Layers 1 and 2 of the ISO/OSI communication model
„ CiA DS-301 (Application Layer and Communication Profile)
C ANopen communication profile
„ CiA DS-302 (Framework for Programmable CANopen Devices)
CANopen Network Management NMT
„ CiA DS-401 (Device Profile for I/O-modules)
„ CiA DS-406 (Device Profile for Encoders)
CANopen device profile for counter modules
„ CiA DS-102 (CAN Physical Layer for Industrial Applications)
General application in the field sector (connectors and bit rates)
on the basis of ISO 11898
2-2
D301006 0806 - BL67 CANopen
CANopen
Communication
The lower layers of CANopen are defined according to the ISO-OSI
model in the ISO 11898 standard.
Communication between the individual nodes is made by transmitting "Telegrams".
4 different types of telegram message are defined for CANopen:
„ Network management messages
„ Service data objects SDO
„ Process data objects PDO
„ Predefined messages
Network Management Messages
Network management messages are used in the network to control
the nodes and their operating states. This type of message makes it
possible, for instance, to configure the data transmission mechanism of a node.
The Network Management objects include Boot-up message,
Heartbeat protocol and NMT message.
Boot-up message, Heartbeat and Node Guarding are implemented
as single CAN frames with 1-byte data field.
The NMT message is mapped to a single CAN frame with a data
length of 2 byte. Its identifier is 0. The first byte contains the
command specifier and the second contains the Node-ID of the
device that must perform the command (in the case of Node-ID 0 all
nodes have to perform the command). The NMT message transmitted by the NMT master forces the nodes to transit to another
NMT state. The CANopen state machine specifies the states Initialization, Pre-Operational, Operational and Stopped. After power-on,
each CANopen device is in the state Initialization and automatically
transits to the state Pre-operational. In this state, transmission of
SDOs is allowed. If the NMT master has set one or more nodes into
the state Operational, they are allowed to transmit and to receive
PDOs. In the state Stopped no communication is allowed except
that of NMT objects.
The state Initialization is divided into three sub-states in order to
enable a complete or partial reset of a node. In the sub-state Reset
Application the parameters of the manufacturer-specific profile area
and the standardized device profile area are set to their power-on
values. In the sub-state Reset Communication the parameters of the
D301006 0806 - BL67 CANopen
2-3
2
Short description of CANopen
communication profile area are set to their power-on values. The
third sub-state is initializing, which a node enters automatically after
power-on. Power-on values are the last stored parameters.
The Heartbeat protocol is for error control purposes and signals
the presence of a node and its state. The Heartbeat message is a
periodic message of the node to one or several other nodes. It indicates that the sending node is still working properly.
Besides Heartbeat protocol there exists an old and out-dated error
control services, which is called Node and Life Guarding protocol. It
is not recommend for implementation.
A device sends the Boot-up message to indicate to the NMT
master that it has reached the state Pre-operational. This occurs
whenever the device initially boots-up but also after a power-out
during operation. The Boot-up message has the same identifier as
the Heartbeat object, however, its data content is zero.
Service Data Objects (SDOs)
A Service Data Object (SDO) reads from entries or writes to entries
of the Object Dictionary.
The SDO transport protocol allows transmitting objects of any size.
The first byte of the first segment contains the necessary flow
control information including a toggle bit to overcome the wellknown problem of doubly received CAN frames. The next three byte
of the first segment contain index and sub-index of the Object
Dictionary entry to be read or written. The last four byte of the first
segment are available for user data. The second and the following
segments (using the very same CAN identifier) contain the control
byte and up to seven byte of user data. The receiver confirms each
segment or a block of segments, so that a peer-to-peer communication (client/server) takes place.
Process Data Objects (PDOs)
Process Data Objects (PDOs) are mapped to a single CAN frame
using up to 8 bytes of the data field to transmit application objects.
Each PDO has a unique identifier and is transmitted by only one
node, but it can be received by more than one (producer/consumer
communication).
2-4
D301006 0806 - BL67 CANopen
CANopen
PDO transmissions
PDO transmissions may be driven by an internal event, by an
internal timer, by remote requests and by the Sync message
received:
2
„ Event- or timer-driven:
An event (specified in the device profile) triggers message transmission. An elapsed timer additionally triggers the periodically
transmitting nodes.
„ Remotely requested:
Another device may initiate the transmission of an asynchronous
PDO by sending a remote transmission request (remote frame).
„ Synchronous transmission:
In order to initiate simultaneous sampling of input values of all
nodes, a periodically transmitted Sync message is required.
Synchronous transmission of PDOs takes place in cyclic and
acyclic transmission mode. Cyclic transmission means that the
node waits for the Sync message, after which it sends its
measured values. Its PDO transmission type number (1 to 240)
indicates the Sync rate it listens to (how many Sync messages
the node waits before the next transmission of its values). Acyclically transmitted synchronous PDOs are triggered by a defined
application-specific event. The node transmits its values with the
next Sync message but will not transmit again until another
application-specific event has occurred.
D301006 0806 - BL67 CANopen
2-5
Short description of CANopen
Special Function Objects
CANopen also defines three specific protocols for synchronization,
emergency indication, and time-stamp transmission.
„ Synchronization object (Sync)
The Sync Object is broadcast periodically by the Sync Producer.
The time period between Sync messages is defined by the
Communication Cycle Period, which may be reset by a configuration tool to the application devices during the boot-up
process. There can be a time jitter in transmission by the Sync
Producer due to some other objects with higher prior identifiers
or by one frame being transmitted just before the Sync message.
The Sync message is mapped to a single CAN frame with the
identifier 128 by default. The Sync message does not carry any
data.
„ Emergency object (Emcy)
The Emergency message is triggered by the occurrence of a
device internal error situation and are transmitted from an Emergency producer on the concerned application device. This
makes them suitable for interrupt type error alerts. An Emergency message is transmitted only once per ‘error event’. As
long as no new errors occurs on a device, no further Emergency
message can be transmitted. Zero or more Emergency
consumers may receive these. The reaction of the Emergency
consumer is application-specific. CANopen defines several
Emergency Error Codes to be transmitted in the Emergency
message, which is a single CAN frame with 8 data byte.
„ Time stamp object (Time)
By means of Time-Stamp, a common time frame reference is
provided to application devices. It contains a value of the type
Time-of-Day. This object transmission follows the producer/
consumer push model. The associated CAN frame has the predefined identifier 256 and a data field of 6-byte length.

Electronic data sheet – EDS file
CANopen nodes are embedded in the CANopen structure by the
help of a standardized EDS file (Electronic Data Sheet).
The EDS file lists all necessary Objects with their corresponding
Sub-indices and the matching entries.

Node-ID Setting
Node-ID Setting
A Node-ID is assigned to every BL67 gateway in the CANopen
structure.
The setting for the Node-ID of the BL67-GW-CO in a CANopen
structure is made through the two rotary coding switches.
The switches can be found beneath a cover, below the service interface.
The BL67 gateway can be used as a CANopen node at any point in
the bus structure.

Attention
If the BL67 gateway is used as the last node in the bus communication, then a special bus connector with a built-in or add-on termination resistor is absolutely necessary!
Note
It is not necessary to address the internal module bus.

BL67 - Gateway for CANopen
Attention
A maximum of 127 Node-IDs (1 to 127) can be assigned in a CANopen structure. Each Node-ID can only be assigned once in the complete bus structure.
The Node-ID 000 must not be assigned. It is reserved for telegrams
that are directed to all the other bus nodes.
The NODE-ID switch on the BL67 CANopen gateway can be used
to assign Node-IDs from 1 to 99!
To set a NODE-ID, proceed as follows:
„ Switch off the supply voltage for the BL67 gateway.
„ Set the rotary coding switches to the required NODE-ID
„ Switch on the supply voltage for the gateway again.
Note
After setting the Node-ID, the protective cover over the switches
must be closed again.
Note
BL67 does not support the assignment of Node-IDs across the bus
network.

Acceptance of the BL67 Station Configuration
Acceptance of the BL67 Station Configuration
When making a new configuration of the BL67 station or an alteration of the existing station structure ("Module list"), the current
configuration must be transferred to the CANopen mirror of the
BL67 gateway. This is done through the set button between the two
rotary encoding switches.
Note
The green "IOs" LED indicates that the current BL67 configuration
matches the stored reference module list.
Pressing the set button with a pointed object for at least 2 seconds
saves the current station configuration in non-volatile memory. A
hardware reset will then be carried out automatically. With this reset,
all the CANopen parameters will be restored to their default values,
if the newly saved configuration is different to the old one.
Attention
When saving the BL67 configuration, all the CANopen objects must
be parameterized again, if their parameter values differ from the default values. The complete parameterization of the station must subsequently be reloaded into the BL67 station.
The actuation of the button is indicated by a rapid (4 Hz) green
blinking of the "IOs" LED. After 2 seconds, the LED changes to
yellow blinking at 4 Hz, thus indicating that the station configuration
is being saved. When the storage procedure is completed, the LED
changes to a continuous green light.

Status Indicators/ Diagnostic Messages Gateway
The gateway transmits the following diagnostics: the status of the
BL67 station, the communication via the internal module bus, the
communication to PROFIBUS-DP and the status of the gateway.
Diagnostic messages are displayed in two ways:
„ via individual LEDs
„ via the software of the respective host system (see Chapter 5,
Section “Diagnostics - Emergency Frames“, Page 5-1 ff.)
Diagnostic Messages via LEDs
Every BL67 gateway displays the following statuses via LEDs:
„ 2 LEDs for module bus communication (module bus LEDs):
GW and IOs
„ 2 LEDs for PROFIBUS-DP communication (fieldbus LEDs):
ERROR and Bus
„ 3 LEDs for monitoring the voltage supply
(system, VCC/ inputs, VI/ outputs, VO).

BL67 - Communication in CANopen
Set up Node Guarding Protocol
Note
Further information on Node Guarding can be found in CiA DS-301.
Node Guarding is the name for the monitoring of network nodes by
a network manager.
In addition, the CANopen network nodes check that their network
manager is operating correctly and that the network is functioning
reliably.
In the default state, Node Guarding is inactive. To activate the Node
Guarding protocol at a node, various parameters must be set for the
Object Dictionary:
„ [100C] = Guard time
Given in milliseconds; the query interval (polling) that is to be
expected by the network slave
Default = 0
„ [100D] = Lifetime factor
This factor, multiplied by the Guard time, is the time that should
elapse after a Node Guarding protocol error before the network
slave generates an error message via EMCY. In this way, a
temporary communication problem, such as may be caused by
heavy bus loading, can be bridged without a Guarding Error.
Default = 0
„ Guard-ID
This is fixed and cannot be changed.
Guarding is initiated with the first Guard-Remote frame (GuardingRTR) from the CANopen network manager.
The Guarding Frame of the network manager has the COBID
"1793 - 1 + Node-ID" and does not have a data field.
Furthermore, the RTR bit in the message header must be set and the
Data Length code = 1.
4-12
D301006 0806 - BL67 CANopen
Setting up communication
The node answers the telegram sent out by the network manager
within the preset time (Guard time) in the "Operational" state, with
the data contents 5. The gateway answers the next polling query
with the contents 133. The following response from the gateway is
with 5 again, and so on. This means that the gateway changes the
state of the most significant bit after every query (i.e. the bit is
toggled).
If the node is in the "Pre-Operational" state, then the value of the
data contents of the response telegram toggles between 127 and
255. If the node is in the "Stop" state, the value toggles between 4
and 132.
If there is no query from the network manager within the preset time,
then the gateway changes to the state "Guard Fail". If output
modules are fitted in the BL67 station, then their outputs will be put
into defined states, depending on the objects "Error mode output"
and "Error state output", or will retain the last state that was
received. Any RxPDOs that are received will still be processed and
output again. If the Guarding starts up again, the BL67 gateway
leaves the "Guard Fail" state, but remains in the Pre-Operational
state.
A "Start Node" command must be generated by the network
manager in order to restart the BL67 gateway (see CiA DS-301).
If the setting is Guard time = 0, then "passive Guarding" will occur.
This means that the gateway answers the Guard Remote frames,
without starting its own internal Guard timer and without changing
into the "Guard fail" state.
As an alternative to Node-/Life-Guarding, the Heartbeat mechanism
newly introduced with DS301 V4.0 is supported, which, unlike
Guarding, does not require Remote frames.

BL67 - Communication in CANopen
Boot-up Message
After initialization (after Power-On, Reset-Node and Reset-Communication), a Boot-up message as per CiA DS-301 V4.0 is sent out.
This is in the form of a guard frame with the contents 00hex.
Under certain circumstances, a network manager may fail to detect
a short drop-out of an BL67 gateway (for example, as a result of
voltage variations). This could occur under the following conditions:
„ The drop-out and initialization of the gateway happen in the time
between two Guarding-Frames
„ The gateway was already in the Pre-Operational state beforehand
„ The last state of the toggle bit was 1
If a Boot-up message is sent out after a reset or initialization, then
the drop-out mentioned above will also not be missed by the
network manager.

D301006 0806 - BL67 CANopen
Parameterization through Service Data Objects (SDO)
Parameterization through Service Data Objects (SDO)
SDO (= Service Data Object) is a confirmed CANopen service that is
primarily used for parameterization and configuration of the
CANopen slaves (BL67) and less frequently for transmitting process
data. "Confirmed" means that an BL67-CANopen gateway (SDO
server) that is addressed by this procedure must acknowledge it
through an response. In this way, the SDO client obtains information
about whether the BL67 gateway that it addressed was contacted,
and whether the access was achieved without any errors (error code
in the response from the SDO server). SDO access means that the
contents of the Object Dictionary entries for an SDO server can be
read or written, and that the settings for an BL67 station can be
made in this way.
Four parallel SDO servers are supported. There are three "additional" SDOs, as well as the default SDO. As a default, these are
inactive, but can be parameterized and enabled through the Object
Dictionary entries 1201hex to 1203hex.
The communication parameters for the default SDO follow the
Predefined Connection Set, and cannot be modified (see CiA DS301, V4.01)
In the following representations of the messages, the identifier of the
CANopen message that is to be sent can be found below the frame,
and the contents of the data byte to be transmitted are within the
frame.
The following representations use the Expedited SDO Transfer, i.e.
a maximum of 4 bytes of user data can be transferred within one
telegram.
Note
CANopen also offers the possibility of segmented SDO-transfer of
data with data length of more than 4 bytes.

Transmission of Process Data Objects (PDO)
Transmission of Process Data Objects (PDO)
CANopen provides PDO communication (PDO = Process Data
Object). PDOs are fast real-time process data that are handled as
unconfirmed services without a protocol overhead. PDOs can
contain a maximum of 8 bytes of data. They can be assembled and
configured by the user to suit the specific requirements. In addition,
there are a number of transmission/transfer settings (Transmission
types) for process data.
The following attributes can be set for each PDO, through the object
"PDO communication parameter":
Communication Parameter COB-ID
The COB-ID is the CAN identifier that is used for the transmission of
a PDO (object 1400hex ff and 1800hex ff).
COB-IDs are used to define the priority of the message telegrams.
The lowest COB-ID has the highest priority.
For communication between 2 nodes, the COB-ID of the transmit
PDO must be the same as the COB-ID of the receive PDO.
Note
As delivered, each BL67 gateway has from none to eight active
PDOs, with COB-IDs that are taken from the Predefined MasterSlave Connection Set.
All other PDOs are inactive. This state can be seen from the invalid
bit (Bit 31) of the COB-ID.

Transmission Type
The Transmission type determines under which circumstances a
PDO can be transmitted or received.
The following PDO Transmission types are supported by BL67:
„ Type 0 (sync)
„ Type 1 (cyclic)
„ Type 253 (remote request)
„ Type 255 (event-driven)

Type 0
The PDO will always be transmitted (TPDO) or evaluated (RPDO) if
this is permitted by a Sync-Frame transmitted by the SYNC
producer and the mapped contents of the BL67-CANopen gateway
have changed since the last transmission.
Type 1
Immediately after receiving each Sync-Frame, the BL67-CANopen
gateway puts out the mapped contents as a PDO on the network,
even if they have not changed since the last transmission.
Type 253
The PDO is only transmitted if a transmitted Remote-Frame
requests this from the BL67-CANopen gateway.
4-22
D301006 0806 - BL67 CANopen
Transmission of Process Data Objects (PDO)
Attention
The following Transmission type (Type 255) is only permissible for
TPDOs.
Type 255
In this mode of operation, the BL67-CANopen gateway does not
depend on any Sync or Remote-Request for PDO communication.
Whenever this is envisaged for an internal event within the BL67CANopen gateway, the gateway will transmit a PDO to the
CANopen network.
The Transmission types of the individual PDOs are independent,
which means that a freely mixed operation with synchronous and
asynchronous PDOs is possible.
Inhibit Time
The setting of an Inhibit time for the PDOs (Object 1800hex ff, SubIndex 03hex) is only supported for TPDOs. Unlike the other time
values, which are given as multiples of 1 ms, the Inhibit time is
defined as a multiple of 100 µs. However, since the time resolution
of the system clock in the BL67-CANopen gateway is 1 ms, Inhibit
time values below 10 x 100 µs are pointless.
Event Timer
The Event timer (Object 1800hex ff, Sub-Index 05hex) defines the
maximum interval after which a TPDO will be transmitted, even
though no event has occurred. This means that the Event timer
determines the maximum interval between two transmissions of a
TPDO.
The expiry of the interval set for the Event timer is detected as an
event. If any other event occurs, the Event timer is reset and
restarted.
The value of the object is interpreted as a multiple of 1 ms.

BL67 - Communication in CANopen
Available PDOs
64 PDOs are supported:
„ 32 Receive PDOs: TPDO1 to TPDO32 (Index 1800hex to 181Fhex)
„ 32 Transmit PDOs: RPDO1 to RPDO32 (Index 1400hex to 141Fhex)
The corresponding Default Master-Slave Connection Set is
supported for each of the PDOs 1 to 4, so that a COB-ID distribution
is not necessary for these PDOs.
If one of the COB-IDs from xPDO1 to xPDO4 is reconfigured, then
the use of a COB-ID from the Default Master-Slave Connection Set
can be achieved by setting this COB-ID to 0.
Mapping Objects in PDOs
Mapping is the assignment of objects from an Object Dictionary in a
PDO for transmission/reception through the CAN-bus. More than
one object can be transmitted in a single PDO.
The Mapping parameters determine which items of information are
transmitted in a PDO:

Communication Profile CiA DS-301 are supported by BL67. The
mapping of these PDOs and their Transmission types are specified
by the I/O-Device Profile CiA DS-401.
4
Note
The Default-PDOs are only activated if the planned objects and subindices actually exist for the corresponding PDO. If, for instance, no
analog I/Os are used in a BL67 station, then the PDOs 2 to 4 are set
to "Invalid" and no mapping entries will be present.
In addition to the default PDOs which are standardized by the CiA
DS-301 and DS-401 profiles, other PDOs for an BL67-CANopen
gateway may be provided with mapping entries and communication
parameters. These additional PDOs (5 to 16) will be set to "Invalid"
as a default.
Default-PDOs as per CiA DS-301 and DS-401
The TPDOs in the following table have the following characteristics:
„ The COB-ID is part of sub-index 01hex
„ The PDO is active!
The first digit of the 8-digit hexadecimal COB-ID-number shows
amongst others, if the PDO is valid. Active PDOs are marked by
a hex-digit < 7. Normally, the digit is 0 or 4 →page 4-83.

BL67-Specific Default-PDOs
These additional PDOs are always set to "Invalid" as a default.
Before enabling these PDOs, the corresponding parameters must
be checked. This applies especially to the COB-IDs, since these are
taken from the Default Master-Slave Connection Set, and are
assigned to other Node-IDs. For this reason, other nodes with the
corresponding Node-ID must not be present in the network, or such
nodes must not use the corresponding COB-IDs.
The Transmission type of these PDOs is generally 255.

Attention
The COB-IDs for the RS×××-Module must be defined by the user!
Example
The own Node-ID of an BL67-CANopen gateway is 1. There are
more than 12 analog input channels. As a result, appropriate
mapping entries are set up for TPDO13 (Object 1A0Chex), and the
COB-ID (Object 180C, Sub-Index 1) is pre-loaded with the value
8000 01A1hex. This PDO can only be enabled without alteration if a
node with the Node-ID 33 (own Node-ID + 32) does not exist, or at
least its TPDO1 is not used.
The following table illustrates the systematic relationship:

Transmission of Process Data Objects (PDO)
Procedure for Altering PDO-Mappings
The Communication Profile CiA DS-301 Version 4 defines a detailed
procedure for altering PDO-mappings.
For the BL67 gateway, this results in the following method for modifying PDO-mappings:
„ The node state of the gateway must be "Pre-Operational".
4
„ The number of mapping entries (Sub-index 0) for a PDO must be
set to 0.
„ The mapping entries (Sub-index 1 to 64) can be written.
„ The number of mapping entries (Sub-index 0) must now be set
to the valid number of mapped objects.
„ Alternatively, the new mapping can be saved in non-volatile
memory (Store Communication parameters).
The following abort codes (Abort-Domain-Protocol) may be sent
back by the gateway in case of an error:

Commands for "Parameter Save" and "Restore Defaults"
Parameter changes that are made through SDO access are only
stored in volatile memory. All alterations that are made by the user
will be replaced by default values at the next Reset Communication,
Reset Node or Power-ON-Boot-Up.
With BL67, it is possible to use a command to make a permanent
save of the communication and/or application parameters. This is
done through the "Store parameters" command (Object 1010hex subindex 1 to 3). The command is executed by using an SDO to write the
data contents 0x6576 6173 ("save") to one of the following entries:
„ 1010hex sub-index 1 saves all parameters
„ 1010hex sub-index 2 saves all communication parameters
„ 1010hex sub-index 3 saves all device parameters (see CiA DS301 V4.01)

Since in some circumstances it may not be possible to restore the

the "Restore default Parameter" command (Object 1011hex subindex 1 to 3) with the following data contents: 0x6461 6F6C ("load").

After the command "Restore default parameters", a Reset Node

Object 100Dhex - Lifetime Factor
If the Lifetime factor is multiplied by the Guard time, the result is the
Lifetime for Node Guarding.
Example:
Guard time:
100 ms
Lifetime factor:
3
The Guard time of 100 ms means that the network nodes expect a
Guard Frame from the master every 100 ms. The Lifetime factor
enables a setting to be made in the BL67-CANopen gateway for
how often a Guard Frame from the Master can be missed before an
error condition is recognized.
In this example, the relevant time would be 300 ms. The evaluation
would only become active after the message had been missing for
300 ms.

Object 1016hex - Consumer Heartbeat Time
The Heartbeat Protocol is used to monitor the operational capability
of other CANopen bus nodes. The Heartbeat Protocol must be seen
as an alternative to Node-/Life-Guarding, which, unlike Guarding,
does not use Remote-Frames.
A device generates the Heartbeat with a specific cycle time (see
object 1017hex "Producer heartbeat time"). Another device receives
the Heartbeat and monitors the cycle time.
Object 1016hex defines the cycle time (interval) at which the Heartbeat is expected. This cycle time should be longer than the corresponding cycle time for the transmitter (see object 1017hex). The
monitoring of the Heartbeat starts when the first Heartbeat Frame is
received. If the Consumer heartbeat time = 0, then the corresponding entry will not be used. The time is set as a multiple of 1 ms.

Object 1020hex - Verify Configuration
Object 1020hex is used to check the station configuration after a
device reset.
The BL67-CANopen gateway supports the non-volatile storage of
parameters. A network configuration tool or an CANopen Manager
can use object 1020hex to test the station configuration after a reset,
and so check whether a reconfiguration is necessary. The configuration tool saves the time and date simultaneously in object 1020hex
and the corresponding DCF file. After a reset, the most recent
configuration and the signature will be restored, either automatically
on request. If the configuration values are altered by some other
command, then the object will be set to 0.
The Configuration Manager compares the signature and the configuration with the values from the DCF file. If it discovers any deviations, a reconfiguration will be necessary.

Objects for the Transfer of Process Output Data
The objects 1400hex to 141Fhex define, together with objects 1600hex
to 161Fhex, which output data have to be transferred via RPDO. In
addition to that, the priority and the transmission type for the RPDOtransfer are defined.
Object 1400hex defines the priority and the transmission type for the
RPDO1. object 1600hex defines the object-index, the sub-index and
the data length for the data which have to be transferred via RPDO1.
Objects 1401hex and 1601hex thus define the RPDO2, objects 1402hex
and 1602hex define RPDO3, etc.

Object 1600hex to 161Fhex - Receive PDO-Mapping Parameter
Objects 1600hex to 161Fhex define, which data have to be transferred
with RPDO1 to RPDO32.
The data content (here: process output data) is represented by
product specific mappable objects.
→ "Mappable Objects", page 4-31.
For example, the process output data for the digital channels are
entered in objects 6200hex, 6220hex etc.
The description of these objects can be found in section "I/OModule Objects", page 4-109 ff..
Sub-indices 01hex to 40hex of the objects 1600hex to 161Fhex contain
the object number, the sub-index and the length of the data that
have to be transferred via the respective RPDO.
An RPDO can transfer a maximum number of 8 bytes (64 bit).
Objects 1600hex to 1603hex (RPDO1 to RPDO4) references by default
the values for the first 64 digital output channels and for the first 12
analog output channels, provided that the values are represented by
the objects 6200hex (digital values) and 6411hex (analog values).

Inhibit time
The setting of an Inhibit time for the PDOs (Object 1800hex ff, SubIndex 03hex) is only supported for TPDOs. Unlike the other time
values, which are given as multiples of 1 ms, the Inhibit time is
defined as a multiple of 100 ms. However, since the time resolution
of the system clock in the BL67-CANopen gateway is 1 ms, Inhibit
time values below 10 x 100 ms are pointless.
Event timer
The Event timer (Object 1800hex ff, Sub-Index 05hex) defines the
maximum interval after which a TPDO will be transmitted, even
though no event has occurred. This means that the Event timer
determines the maximum interval between two transmissions of a
TPDO.
The expiry of the interval set for the Event timer is detected as an
event. If any other event occurs, the Event timer is reset and
restarted.
The value of the object is interpreted as a multiple of 1 ms.

The Reset Node Identifier (Sub-index 01hex) determines whether, in
the event of a Reset Node command, a normal fast reset should be
performed, or a hard processor reset, which can take several
seconds to be carried out.
For writing, the value that is transferred in Unsigned32 format will be
interpreted as a string:

After the next Reset-Node or the next "Reset Communication"

The Index "Save reference module list" (Sub-index 02hex) determines that, in the event of a Reset Node command, the BL67 reference module list (Objects 3080hex and 3081hex) will be saved in nonvolatile memory, and then followed by a hard processor reset. This
hardware reset is necessary, because changes to the BL67 reference module list cannot be dynamically accepted in the CANopen I/
O mirror. If the module list is altered, all the CANopen parameters
will be reset to the default values.

The object represents the measured values for the analog input
modules with 16 bits for each channel.
Attention
The process data traffic for the analog input values is not started until the object 6423hex is switched from the default setting FALSE to
TRUE!
The representation of the different measured values as numerical
values is described in detail from a page 26 onward for each value
range.
Attention
The possibility of 12-bit value representation (left-justified) is not
useful for CANopen since all reference values (upper limit, lower limit) must be defined with 16 bits.

Objects 6421 – 6428hex can be used to control the event-triggered
transmission of the process input data. As well as these event-triggered control objects, the transmission frequency of the process input data is also controlled by means of objects 1800hex to 181Fhex.
Attention
Remember that the object a "6423hex Analog input global interrupt
enable", page 4-152 must be used in order to enable the possibility
of transmitting the process input data using an interrupt signal!
The object defines which event is to trigger the transmitting of the
analog input data (TPDOs) by means of an interrupt signal.
The triggering event is defined for each input channel using a corresponding sub-index of the object.

6422hex - Analog Input Interrupt Source
The object indicates if an analog input channel has fulfilled a condition for triggering an interrupt signal.
The conditions were defined with object 6421hex.
If a condition for triggering an interrupt signal on a channel is
fulfilled, the corresponding bit is set to 1. The corresponding bits for
channels 0 to 31 are set in sub-index 01hex and the bits for channels
32 to 63 in sub-index 02hex etc.
The bits can be read using an SDO: The read operation causes the
bits to be reset to 0.

Process input data is data that is transmitted from the connected
field device via the BL67-1RS232 module to the communication
partner (e.g. PLC). The data received from the device by the BL671RS232 module is entered in a 128 byte receive buffer and then
transferred in segments to the communication partner via the
module bus and the gateway.
This is transferred in an 8-byte format as follows:
„ 6 bytes or 7 bytes are used to contain the user data.
„ 1 byte contains the diagnostics data depending on the parameter setting.
„ 1 status byte is required to ensure trouble-free transmission of

The SSI Diag mapping object writes and reads register 51
(REG_SSI_MASK) of the BL67-1SSI module.
The REG_SSI_MASK contains the SSI encoder diagnostics transferred.
Some SSI encoders not only transfer the position value in the data
frame that they transfer to the module but also supply additional
status messages. It is advisable to include these status messages in
the application in order to analyze the measured value.
Writing the REG_SSI_MASK register allows up to four individual bits
to be taken from the SSI encoder data frame and transferred to the
SSI_STSx bits of the process input data. It is also possible to output
the "SSI encoder group diagnostics message" with an acyclic diagnostics operation when a status message is initiated.

Diagnostics - Emergency Frames
General
The gateway sends out the following diagnostic information: the
state of the BL67 station, the communication through the internal
modules bus, the communication with CANopen, the state of the
gateway itself.
Diagnostics messages are indicated in two different ways:
„ through the individual LEDs
„ through Emergency Frames in a CANopen configuration tool
(software)

Structure of the Emergency Frames
Structure of the Emergency Frames
BL67 CANopen supports Emergency Frames (EMCY) as standardized in CiA DS-301.
The COB-IDs for the EMCY telegrams are defined by the Predefined
Master-Slave Connection Set:
COB-ID = 129 - 1 + Node-ID
In the event of a communication error, not only the Emergency Error
Code but also the Error register (see "Object 1001hex") and additional information will be transmitted, so that the error can be more
precisely identified. Only a portion of the 5 bytes is used for the additional information. The remaining bytes are then 0.

Guidelines for Electrical Installation
General Notes
General
Cables should be grouped together, for example: signal cables,
data cables, heavy current cables, power supply cables.
Heavy current cables and signal or data cables should always be
routed in separate cable ducts or bundles. Signal and data cables
must always be routed as close as possible to ground potential
surfaces (for example support bars, cabinet sides etc.).
Cable Routing
Correct cable routing prevents or suppresses the reciprocal influencing of parallel routed cables.
Cable Routing Inside and Outside of Cabinets:
To ensure EMC-compatible cable routing, the cables should be
grouped as follows:
Various types of cables within the groups can be routed together in
bundles or in cable ducts.
Group 1:
„ shielded bus and data cables
„ shielded analog cables
„ unshielded cables for DC voltage ≤ 60 V
„ unshielded cables for AC voltage ≤ 25 V
Group 2:
„ unshielded cables for DC voltage > 60 V and ≤ 400 V
„ unshielded cables for AC voltage > 25 V and ≤ 400 V
Group 3:
„ unshielded cables for DC and AC voltages > 400 V
The following group combination can be routed only in separate
bundles or separate cable ducts (no minimum distance apart):
Group 1/Group 2
7-2
D301006 0806 - BL67 CANopen
General Notes
The group combinations:
Group 1/Group 3 and Group 2/Group 3
must be routed in separate cable ducts with a minimum distance of
10 cm apart. This is equally valid for inside buildings as well as for
inside and outside of switchgear cabinets.
Cable Routing Outside Buildings
Outside of buildings, cables should be routed in closed (where
possible), cage-type cable ducts made of metal. The cable duct
joints must be electrically connected and the cable ducts must be
earthed.
7
Warning
Observe all valid guidelines concerning internal and external lightning protection and grounding specifications when routing cables
outside of buildings.
Lightning Protection
The cables must be routed in double-grounded metal piping or in
reinforced concrete cable ducts.
Signal cables must be protected against overvoltage by varistors or
inert-gas filled overvoltage arrestors. Varistors and overvoltage
arrestors must be installed at the point where the cables enter the
building.
Transmission Cables
The slaves on the bus are connected to one another with fieldbus
lines that correspond to the DeviceNetTM specification (ODVA Spec.
Rel. V2.0).
D301006 0806 - BL67 CANopen
7-3
Guidelines for Electrical Installation
The bus cables must be terminated at the beginning and end with a
bus terminating resistor. This can be connected via the number 4
DIP switch on the gateway.

Potential Relationships
Potential Relationships
General
The potential relationship of a CANopen system realized with BL67
modules is characterized by the following:
„ The system supply of gateway and I/O modules as well as the
field supply are realized via one power feed at the gateway.
„ All BL67 modules (gateway, Power Feeding and I/O modules),
are connected capacitively via base modules to the mounting
rails.
The block diagram shows the arrangement of a typical BL67 station.

Guidelines for Electrical Installation
Electromagnetic Compatibility (EMC)
BL67 products comply in full with the requirements pertaining to
EMC regulations.
Nevertheless, an EMC plan should be made before installation.
Hereby, all potential electromechanical sources of interference
should be considered such as galvanic, inductive and capacitive
couplings as well as radiation couplings.
Ensuring Electromagnetic Compatibility
The EMC of BL67 modules is guaranteed when the following basic
rules are adhered to:
„ Correct and large surface grounding of inactive metal components.
„ Correct shielding of cables and devices.
„ Proper cable routing – correct wiring.
„ Creation of a standard reference potential and grounding of all
electrically operated devices.
„ Special EMC measures for special applications.
Grounding of Inactive Metal Components
All inactive metal components (for example: switchgear cabinets,
switchgear cabinet doors, supporting bars, mounting plates, tophat
rails, etc.) must be connected to one another over a large surface
area and with a low impedance (grounding). This guarantees a standardized reference potential area for all control elements and
reduces the influence of coupled disturbances.
„ In the areas of screw connections, the painted, anodized or
isolated metal components must be freed of the isolating layer.
Protect the points of contact against rust.
„ Connect all free moving groundable components (cabinet doors,
separate mounting plates, etc.) by using short bonding straps to
large surface areas.
7-6
D301006 0806 - BL67 CANopen
Electromagnetic Compatibility (EMC)
„ Avoid the use of aluminum components, as its quick oxidizing
properties make it unsuitable for grounding.
Warning
The grounding must never – including cases of error – take on a dangerous touch potential. For this reason, always protect the ground
potential with a protective cable.
PE Connection
A central connection must be established between ground and PE
connection (protective earth).
Earth-Free Operation
Observe all relevant safety regulations when operating an earthfree
system.
Mounting Rails
All mounting rails must be mounted onto the mounting plate with a
low impedance, over a large surface area, and must be correctly
earthed.

Guidelines for Electrical Installation
Mount the mounting rails over a large surface area and with a low
impedance to the support system using screws or rivets.
Remove the isolating layer from all painted, anodized or isolated
metal components at the connection point. Protect the connection
point against corrosion (for example with grease; caution: use only
suitable grease).
7-8
D301006 0806 - BL67 CANopen
Shielding of cables
Shielding of cables
Shielding is used to prevent interference from voltages and the radiation of interference fields by cables. Therefore, use only shielded
cables with shielding braids made from good conducting materials
(copper or aluminum) with a minimum degree of coverage of 80 %.
The cable shield should always be connected to both sides of the
respective reference potential (if no exception is made, for example,
such as high-resistant, symmetrical, analog signal cables). Only
then can the cable shield attain the best results possible against
electrical and magnetic fields.
A one-sided shield connection merely achieves an isolation against
electrical fields.
Attention
When installing, please pay attention to the following...
– the shield should be connected immediately when entering the
– system,
– the shield connection to the shield rail should be of low
– impedance,
– the stripped cable-ends are to be kept as short as possible,
– the cable shield is not to be used as a bonding conductor.
If the data cable is connected via a SUB-D connector, the shielding
should never be connected via pin 1, but to the mass collar of the
plug-in connector.
The insulation of the shielded data-cable should be stripped and
connected to the shield rail when the system is not in operation. The
connection and securing of the shield should be made using metal
shield clamps. The shield clamps must enclose the shielding braid
and in so doing create a large surface contact area. The shield rail
must have a low impedance (for example, fixing points of 10 to
20 cm apart) and be connected to a reference potential area.
The cable shield should not be severed, but routed further within the
system (for example, to the switchgear cabinet), right up to the interface connection.

Guidelines for Electrical Installation
Note
Should it not be possible to ground the shield on both sides due to
switching arrangements or device specific reasons, then it is possible to route the second cable shield side to the local reference potential via a capacitor (short connection distances). If necessary, a
varistor or resistor can be connected parallel to the capacitor, to
prevent disruptive discharges when interference pulses occur.
A further possibility is a double-shielded cable (galvanically separated), whereby the innermost shield is connected on one side and the
outermost shield is connected on both sides.

Potential Compensation
Potential Compensation
Potential differences can occur between installation components
that are in separate areas and these
„ are fed by different supplies,
„ have double-sided conductor shields which are grounded on
different installation components.
A potential-compensation cable must be routed to the potential
compensation.
Warning

Never use the shield as a potential compensation.

A potential compensation cable must have the following characteristics:
„ Low impedance. In the case of compensation cables that are
routed on both sides, the compensation line impedance must be
considerably smaller than that of the shield connection (max.
10 % of shield connection impedance).
„ Should the length of the compensation cable be less than 200 m,
then its cross-section must be at least 16 mm2 / 0.025 inch2. If
the cable length is greater than 200 m, then a cross-section of at
least 25 mm2 / 0.039 inch2 is required.
„ The compensation cable must be made of copper or zinc coated
steel.
„ The compensation cable must be connected to the protective
conductor over a large surface area and must be protected
against corrosion.
„ Compensation cables and data cables should be routed as close
together as possible, meaning the enclosed area should be kept
as small as possible.
