Operating Instructions, 03/2022, A5E39895388-AC 11
2.2 Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. firewalls and/or network segmentation)
are in place.
For additional information on industrial security measures that may be implemented, please
visit (https://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers' exposure to
cyber threats.

3.2 Changes compared to the previous version
What is new as of firmware version V2.0 in HSP_V17_0358_001_Link_PN_CAN_V2.0?
There are now two entries in the HW catalog for the PN/CAN LINK module with firmware
versions V1.0 and V2.0. The difference between versions V1.0 and V2.0 is the "Simple slave
functionality" included in PN/CAN LINK V2.0.
The "Simple slave functionality" is available as of TIA Portal V17 and enables the PN/CAN LINK
to work with CANopen devices that do not fully comply with the CANopen standards defined
by the CiA group (https://www.can-cia.org/). You can find additional information below.
Note
Using PN/CAN LINK V2.0
Before downloading a configuration of the PN/CAN LINK V2.0,
a firmware update of the
device to version V2.0 is required.
Note
Use of a new PN/CAN LINK V2.0 (firmware version 2.0 and higher) as replacement for a
device with firmware V1.0
It is
not possible to use a device with firmware V2.0 with a project that requires firmware
V1.0. To bypass this restriction, you must upgrade th
e PN/CAN LINK in the project from V1.0
to V2.0. More information is available in the section "Using an existing configuration" in the
chapter
Installation and handling of the new HSP (Page 19).
If you are not making any changes after the upgrade, the new device will work just like the
old one. More information is available in the chapter Firmware update (Page 149).
Note
Backward compatibility
For an existing configuration of the PN/CAN LINK V2.0, a downgrade from V2.0 to V1.0 is not
possible within a TIA Portal project. When a downgrade is
required, you must create a new
PN/CAN LINK module for V1.0 within a TIA Portal project. In this case, however, the "Simple
slave functionality" is not available.
You can perform a firmware update/firmware downgrade without any restrictions.

New properties/functions
3.2 Changes compared to the previous version
SIMATIC PN/CAN LINK
14 Operating Instructions, 03/2022, A5E39895388-AC
New parameters
Under "CANopen Manager > Communication"
•Max. SDO timeout
Some "simple slave" devices are slow to respond to commands of the CANopen Manager.
Such devices work on other, more important tasks and CANopen communication has low
priority. The reaction to the command from the manager is therefore delayed. In this case,
the manager waits for the "max SDO timeout" (ms). The SDO- request is aborted when the
preset time has elapsed. There is also a 1 second delay before a new request is sent.
The SDO Timeout is only displayed to the user when an SDO with the data record number
0x200 - 0x20F is requested. The timeout is displayed instead of the 4-byte code "Additional
error information code" as 0x05040000 (code number taken from CiA standard "CiA 301").
This code occupies the 6th to 9th byte of the data record read.
•Max. BootUp timeout
The max. bootup timeout gives the maximum response time in seconds for the startup
process of a node. When a node does not respond to the requests of the manager within the
specified time, the diagnostic message "BootUp, node not responding" is sent to the PLC. The
diagnostic message is deleted as soon as the node responds correctly to the manager.
Under "CANopen Manager > Diagnostics"
For PN/CAN LINK V2.0, the menu "CANopen Manager > Response to EMCY message" is
changed to "CANopen Manager > Diagnostics" .
•Check box Response to EMCY message: Pass event as diagnostics to S7
This option has merely been renamed.
When you select this option, all received EMCY messages are sent to the IO controller as
diagnostic alarms.
•Check box Enable diagnostic alarms for not mandatory nodes
The option applies only to nodes that are not mandatory.
When you disable this option, the disconnection of the nodes from the CAN bus or error
messages that are pending in the CANopen network are not sent to the diagnostic buffer and
the ERROR LED remains off.
When you select this option, error messages from such nodes are displayed in the diagnostic
buffer and the ERROR LED lights up.
All other nodes on the CAN bus are not affected by this option.
•Check box Enable additional diagnostics alarms
When you disable this option, the device does not send diagnostic alarms related to the
operating mode (CANopen Manager, CANopen Slave and CAN transparent). Both error LEDs
remain off.

New properties/functions
3.2 Changes compared to the previous version
SIMATIC PN/CAN LINK
Operating Instructions, 03/2022, A5E39895388-AC 15
•Check box Block Error passive alarm
When you select this option, the error passive state of the CAN bus is not reported as an
alarm in the diagnostic buffer. The error LED remains off.
(ISO 11898 CAN Layer 2 device: If one of the error counters is above 127, the device goes
into the "Error Passive" state of the CAN bus. The next error is signaled by a "Passive Error
Flag", which consists of 6 recessive bits. This signal does not destroy any other
communication on the bus. The device is fully operational unless an error counter exceeds
255 and the device goes into the "Bus Off" state.)
Under "CANopen Manager > Receive process data objects (PDOs) > Receive PDO
definition"
•Check box Disable checking of PDO length
When you select this option, the data length (number of received bytes) of the received PDOs
is adjusted. Error, warning or diagnostic messages are not generated. The value is adjusted to
the correct data length as follows:
•Data below the defined length are supplemented with the value 0.
•If data exceeds the defined length, the more significant bytes are deleted.
When you disable this option, all data from a received PDO with a length deviating from the
standard is discarded and replaced with the value of the last valid PDO (last received PDO
with the correct length). The CANopen Manager calls up an error message in the diagnostic
buffer.
Under "CANopen node universal > Communication"
•Check box No NMT / Layer 2 slave
When you select this option, the requested NMT status of the node is not evaluated by the
Manager. The CANopen configuration phase is completely skipped for this node. The
configuration menus for EMCY, Heartbeat and Node Guarding as well as the PDOs are
blocked (write-protected) and show the values from the object dictionary (EDS file).
Exception: A node can be monitored by the manager using the Heartbeat/Node Guarding
functions. An error is only signaled to the CPU when the Heartbeat/Node Guarding message is
not received in time. The NMT status of the message is not evaluated; any status is accepted.
Typical use case for this option are slave nodes that do not require NMT commands for their
commissioning and use. After power-on, such devices immediately enter the operating mode
and start sending the PDO messages configured by default.
If you have made parameter changes before setting the "No NMT / Layer 2 slave" option,
these values are retained. However, they have no effect on the actual configuration of the
node in the system.

3.2 Changes compared to the previous version
SIMATIC PN/CAN LINK
16 Operating Instructions, 03/2022, A5E39895388-AC
•Check box Loose configuration
The main purpose of this option is to ignore unexpected errors during the configuration
phase. The configuration of the node is always completed even when a configuration error
occurs.
This option only affects the configuration phase after startup or after resetting the bus or
node. The status of a node is read by the master during the configuration phase, although it
is ignored. In this way, the master can complete the configuration with devices that reject
incoming messages randomly or with devices that communicate differently, contrary to the
definition in their EDS file.
When a node does not support one of the mandatory objects 1000, 1018.01, 1018.02,
1018.03, this check box is always selected and cannot be cleared.
•Check box Disable this node temporarily
You have configured a series of nodes in the TIA Portal, but one node does not physically
exist in the CAN network. To work with the "reduced" network, you can temporarily disable
one or more nodes. Such a CANopen node with its entire configuration remains in the project
but is not downloaded to the PN/CAN LINK. The node does not exist in the configuration that
is used by the PN/CAN LINK. No errors or warnings are generated by the PN/CAN LINK.
Under "CANopen Slave > Diagnostics"
This menu is new for PN/CAN LINK V2.0 in "CANopen Slave" mode.
•Check box Enable additional diagnostics alarms
When you disable this option, the device does not send diagnostic alarms related to the
operating mode (CANopen Manager, CANopen Slave and CAN transparent). Both error LEDs
remain off.
•Check box Block Error passive alarm
When you select this option, the error passive state of the CAN bus is not reported as an
alarm in the diagnostic buffer. The error LED remains off.
(ISO 11898 CAN Layer 2 device: If one of the error counters is above 127, the device goes

communication on the bus. The device is fully operational unless an error counter exceeds
255 and the device goes into the "Bus Off" state.)
Under "CAN transparent > Diagnostics"
This menu is new for PN/CAN LINK V2.0 in "CAN transparent" mode.
•Check box Enable additional diagnostics alarms
When you disable this option, the device does not send diagnostic alarms related to the
operating mode (CANopen Manager, CANopen Slave and CAN transparent). Both error LEDs
remain off.

network upon RD-SDO request. Contrary to the definition in the CiA standard "CiA 302 Part 2",
this object is implemented read-only. Write access is not permitted. When the manager itself
wants to read data of this object, it must use the RDREC instruction with data record number
0x211 for this.
Note
This functionality is only available in the "CANopen Manager" operating mode.
It returns an array of 127 bytes for the status of the node ID from 1 to 127.
RET ARRAY[0] = Status of node 1
RET ARRAY[1] = Status of node 2
...
RET ARRAY[126] = Status of node 127
Note
Reading from 0x1F82OD with the SDO command only returns a status
byte of a node instead
of an array of bytes. For each node, therefore, an SDO command must be sent with the ID of
the requested node as an input parameter.
The status of a node can have the following values (according to CiA standard "CiA 302 Part
2"):
•0 = unknown state or NMT/BOOTUP
•1 = node missing
•4 = NMT/STOPPED
•5 = NMT/OPERATIONAL
•127 = NMT/PRE-OPERATIONAL

Installing HSP_V17_0358_001_Link_PN_CAN_V2.0
To work with firmware version V2.0 and the new functions, you must use the
HSP_V17_0358_001_Link_PN_CAN_V2.0. You can configure a PN/CAN LINK with firmware
version V1.0 using the same HSP.
If necessary, you can download and install the "HSP_V17_0358_001_Link_PN_CAN_V2.0"
from Siemens Industry Online Support.
You can find the Hardware Support Packages (HSP) as a download on the Internet
(https://support.industry.siemens.com/cs/us/en/view/72341852).
The HSP_V17_0358_001_Link_PN_CAN_V2.0 is only available for the TIA Portal version V17.
