7.13 J1939 and the Loader Monitor
This screen appears when the Program Loader
Monitor is connected to the DVC710 and the status
button next to J1939 on the main menu screen is
clicked. The J1939 status button appears on the main
PLM Screen if J1939 messages programmed in the
application.
Messages
This text box located in the upper left hand corner of
the screen indicates the number of messages
programmed into the current application.
Coolant Temperature Indicator
This text box located in the upper left hand corner of
the screen indicates the coolant temperature in degrees C or F as selected by the switch next to it on the
screen, if the message 65262 is present on the bus.
Message Decoders
There are two separate message decoders at the top of the J1939 screen. The first will display the bit status of
the selected message and byte. The second allows the user to apply gain and offset to a message from 1 to 3
bytes of data. For example, the Engine Temperatures Coolant Temperature data is a 1 byte message with an
offset of -40 and a gain of 0, while the EEC1, Engine RPM message is 2 bytes with 0 offset and a gain of 8.
PGN #_SS
This column allows the user to select a PGN number with a specific source address from a pull down list. The
pull down list is derived from the messages defined within the application. The specific Source Address for the
message is indicated by an under bar (i.e. message; 61444_0 would indicate the EEC1 message from source
address 0). The data for this PGN number will be displayed in the corresponding row.
PGN Name
This column allows the user to enter a name for the selected PGN number for that row.
PGN Data Windows
This column allows the user to see the data for the PGN number for that row. It will change background colors
to indicate a good response, bad response or disabled message.
T/R Can
This column allows the user to determine whether the selected PGN number for that row is a transmit or receive
message and what physical bus it is received or transmitted on.
Display Time/Date
This Check Box when selected will append the time and date to each message displayed as it is received.
Log Rate
This setting defines the amount of time in seconds between data samples when logging.
Log Messages to File
Allows for saving the J1939 messages to a .CSV file. When this button is pressed, the user is prompted to
create a save file. Then the DVC710 will begin logging messages.
