The J1939 network address associated with
the data point.
If this is an input data point, messages
received must match both the PGN and source
address to be used for this data point. If the
Target Address is 255, any message with a
matching PGN, regardless of source address
will be accepted.
If this is an output data point, the destination
address of the transmitted message will be set
to the Target Address. The message will be
broadcast if the Target Address is set to 255.
The desired update rate for the data point in
milliseconds.
If this is in input data point, the data point is
expected to be updated (a message received
with matching PGN and address) within the
configured Update Rate. If no update is
received within the configured time, the mod-
ule will request the data point's PGN by trans-
mitting a Request PGN to the Target Address.
If the Update Rate is set to 0, the PGN will
never be requested.
If the Update Rate is non-zero for an input
point, and no update is received after an
update period, the data associated with the
PGN in the input table is set to 0xFF.
If this is an output data point, this is the rate at
which the associated message will be trans-
mitted on the network. If the Update Rate is
set to 0, the message will only be transmitted
when a Request PGN is received for the con-
figured PGN.
