as messages to be received from the engine.
J1939 Message Set-up
The Programming tool has no pre-defined
J1939 Messages. The user is required to
configure the messages correctly; most
message information can be obtained from
the SAE manuals.
Command Name
The name prefix used in the bubble logic
screen to access this message’s data and
status.
Range: 16 Alpha/Numeric characters only
with no spaces.
Control
The Control field specifies if the message
will sent to or received from the engine’s
ECM.
Range: Receive Data or Send Data
Maximum Time
The meaning of this field is dependent on the Control type. If the Control type is Send Data then this field means
how often the message is transmitted out from the DVC710 controller. If the Control type is Receive Data then
this field means how often the message is expected to be received. It is recommended that the user set the
Maximum Time for receive messages to at least three times the expected transmission rate.
Range: 10ms to 10seconds.
PDU Format (PF)
The PDU Format field identifies one of two PDU formats able to be transmitted (PDU1 or PDU2). PDU Formats
are described in the SAE J1939/21, Section 3.3.
Range: 0 to 255
PDU Specific (PS)
The meaning of this field is dependent on the value of PF. If the PF value is between 0 and 239 (PDU1), this PS
field contains a destination address. If the PF field is between 240 and 255 (PDU2), the PS field contains a
Group Extension (GE). The Group Extension provides a larger set of values to identify messages, which can be
broadcast to all ECUs on the network.
Range: 0 to 255
Specific Source Address Check Box
Select to assign a specific source address to a message. If not checked, outgoing messages will contain the
Default Source Address from the J1939 Main Screen and incoming messages will not be filtered for a source
address. When checked, a field will open to allow the programmer to enter a specific source address.
Priority
The Priority field assigns how important the message is to be processed. The highest priority is 0 and lowest
priority is 7. (This field is not needed when “Control” type is “Receive Data”)
Range: 0 to 7
Data Length
Data Length is the length of the message in bytes.
