8Operating Instructions, 12/2018, A5E45307564-AA
Safety information
WARNING
Connection only over safety extra-low voltage / protective extra-low voltage
May cause death or serious injury
The device is designed for operation using directly connectable safety extra-low voltage
(SELV) with safe electrical separation according to IEC 60950-1 / EN 60950-1 /
VDE 0805-1 or IEC 61131-2 / EN 61131-2 / DIN EN 61131-2.
To obtain the safe property of low-voltage circuits of the PN/J1939 LINK, the 24 V rated
voltage supply and external connections to communication interfaces must be supplied
from approved sources that meet requirements set forth by various standards for
SELV/PELV voltage-limited sources.
Therefore only connect safety extra-low voltages (SELV) with safe electrical separation
according to IEC 60950-1 / EN 60950-1 / VDE 0805-1 to the supply voltage connections
and the communications interfaces.
Working on the device or on connected components
WARNING
Risk of electric shock
May cause death or serious injury
•Voltages > 60 V DC or 30 V AC may be present in the control cabinet. Therefore
appropriate safety precautions must be taken to prevent contact during commissioning
and maintenance work.
•Before carrying out any work on the device or on connected components, make sure
that the installation is in a zero-voltage state.
•Use cable types with UL approval for UL-approved systems.

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 only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit
(http://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.

communication gateway between a PROFINET network and a J1939 network.
Figure 3-2 System configuration with PN/J1939 LINK
Purpose and function of the system components
PN/J1939 LINK enables PROFINET to be connected to a J1939 network.
Communication of the PN/J1939 LINK with the CPU of the S7 controller takes place
exclusively via the PROFINET interface.
From a PROFINET perspective, the PN/J1939 LINK is an IO device according to
Conformance Class B (CC-B).
From a J1939 perspective, the PN/J1939 LINK is an Electronic Control Unit (ECU) and
contains a Controller Application (CA).
The cyclic data exchange between the PN/J1939 LINK and the connected S7 CPU takes
place via an update of the IO image. Acyclic communication takes place by means of the
"Read data record" and "Write data record" services.
PN/J1939 LINK is powered either via an external 24 V DC power supply unit or via the
24 V power supply of the SIMATIC S7 system.
The TIA Portal is used for configuring. A corresponding GSDML file is available for this
purpose.

J1939 protocol
Extended CAN format
The J1939 protocol uses the Extended CAN Format CAN 2.0B (29-bit message ID).
The 29-bit message ID consists of the following:
Figure 4-1 29-bit message ID
●Message priority. The priority of a message is used for the bus arbitration. The value 0
has the highest priority.
●Parameter Group Number (PGN)
●Address of the device that transmits the message.
Parameter Group Number (PGN)
A key element of the J1939 protocol is the Parameter Group Number (PGN). The type of a
message can be determined or recognized by means of the PGN.
Figure 4-2 Parameter Group Number (PGN)
User-specific PGN
Any combination of "PDU Format" and "PDU Specific" parameters is permitted for
configuration in the TIA Portal. Requirement: The combination is within the permissible value
range and not reserved for special purposes.

J1939 device name (Name Field)
The device name is a numeric 64-bit value. The name contains the following information:
●Identification of the device and the device function
●Determines whether the PN/J1939 LINK can select a different network address if it loses
"Address Claiming".

SIMATIC PN/J1939 LINK
Operating Instructions, 12/2018, A5E45307564-AA 17
Address claiming
Addresses for J1939 devices are assigned using the "Address Claiming" procedure. With
"Address Claiming", each J1939 device sends its desired network address and its J1939
name with PGN 60928. If no other device is using this address, the preferred address can be
used. If the address is already in use, the respective devices compare their names. The
name with the lowest numeric value "wins" the conflict and the corresponding device can use
the address.
With PN/J1939 LINK, you can configure whether the device is able to change its network
address (Arbitrary Address Capable). The parameters are set via the corresponding bit of
the device name:
Table 4- 1 Device name - "Arbitrary Address Capable" field (1-bit)
Value
Meaning
Behavior for address claiming
Bit = 0 PN/J1939 LINK cannot
change its address.
If another device claims the same address with a higher priority,
the PN/J1939 LINK performs the following actions:
•PN/J1939 LINK sets its address to 254 (Null address).
•PN/J1939 LINK sends the diagnostics alarm "Invalid ad-
dress" to the S7 controller. See Diagnostic messages
(Page 58).
PN/J1939 LINK can no longer participate in J1939 communica-
tion and must be configured with a new J1939 network address.
Bit = 1 PN/J1939 LINK can
change its address.
If another device claims the same address with a higher priority,
the PN/J1939 LINK performs the following actions:
•PN/J1939 LINK increments its current address.
•PN/J1939 LINK sends the diagnostics alarm "Network ad-
dress changed" to the S7 controller. See Diagnostic mes-
sages (Page 58).
PN/J1939 LINK can continue to participate in J1939 communi-
cation.
After a restart, PN/J1939 LINK uses the "Source Address" con-
figured in the TIA Portal again.
Peer-to-peer and broadcast communications
The J1939 protocol makes it possible to send messages either to all subscribers (broadcast)
on the bus or to individual subscribers at specific addresses (peer-to-peer).

Functions
4.1 J1939 protocol
SIMATIC PN/J1939 LINK
18 Operating Instructions, 12/2018, A5E45307564-AA
Transport protocols
Parameter groups with a maximum data length of 8 bytes can be transmitted within a J1939
data packet.
The following transport protocols are available for the transmission of data volumes larger
than 8 bytes.
●BAM (Broadcast Announce Message)
●CMDT (Connection Mode Data Transfer)
BAM messages are sent to all J1939 devices and require no handshaking.
CMDT messages are exchanged peer-to-peer between two J1939 devices. CMDT works
with a handshake method for data flow control.
DM messages
J1939 ECUs send DM messages to report their active DTCs (Diagnostic Trouble Codes) and
the corresponding lamp status. PN/J1939 LINK can read diagnostic data from the other
connected ECUs. The structure of a DM message corresponds to that of a standard PGN.
Transmission takes place via a multipackage protocol (BAM).
DM1 messages have a PGN (Parameter Group Number) of 65226 and a cycle of 1 second.
If data lengths of up to 512 bytes are sufficient, standard input modules can be used for the
configuration.
For data lengths greater than 512 bytes, configuration takes place via input proxy modules.
The maximum data length is 1785 bytes.
If the PGN 65226 is configured in TIA as an input module with a data length of greater than 8
bytes, a corresponding diagnostics alarm is sent to the S7 controller if there is a change of
the received DM1 data compared to the previous value.
