Transmit Message Data

Transmit Message Data
The application is able to control the data transmitted by defined messages using the
following mechanism.
j1939.canX.pgnYYYYYY.saZZ
Event j1939.canX.pgnYYYYYY.saZZ
Event Data
Keys Values Description
[parameters]
<parameter data> Each parameter in the message is accessible using the
parameter name as the key.
Direction
output
Channel
j1939
Notes
Sent from the application to the J1939 service. The path is described generically
where:
•
canX is the name of the interface
• pgnYYYYYY is the PGN of interest
• saZZ is the source address of the target CA.
For example, data for PGN 0xF004 from SA 0x00 on interface can0, the path would
be:
j1939.can0.pgn61444.sa0 .
Note that all PGN and SA values must be specified in decimal notation (base 10).
Lua Example
Note that the example adjusts the testParameter parameter of PGN 0xFFFF.
testParameter is an unsigned 32-bit value.
function cb_update_ffff ( mapargs )
local ev = mapargs .context_event_data
local data = {}
data [" test_parameter "] = sendData
gre .send_event_data(" j1939.can1.pgn65535.sa10", "4u1 test",
data , " j1939 ")
sendData = sendData + 1
