Vehicle Spy Text API: ECU Object
Objective
ECU specific functionality is accessed via the ecu object. The syntax is as follows: ecu.sim.simulatetransmitmessages 0 ;simulate the receive messages for those in the ECU collection
ECU Object
Command Name
Description
Example
sim
Accesses the ECU simulator.
ecu.sim.compile ;compile the simulator
ecu.sim Object
Command Name
Description
Example
compile
Compiles the changes made to the ECUs collection. It will regenerate the tx message collection. and copy the signals from the signal collect.
defaultsignaltype
This is an enumerated constant indicated for signals not accounted for in the signals collection or the replay data file.
ec
Accesses the collection of Simulator ECUs for simulation.
isrunning
Indicates if the simulator is running or not.
ecu.sim.isrunning?
manualstart
Set/Returns if the simulator starts when Vehicle Spy starts.
replaydatafile
Set/Returns if the name of the vehicle spy log file used for replay.
repeatreplay
Set/Returns if the replay should automatically restart when the file completes.
start
Starts the simulator.
stop
Stops the simulator.
simulatenormal
Returns/Sets if the ECUs should simulate normal messaging.
simulatediagnostics
Returns/Sets if the ECUs should simulate diagnostics messaging.
simulatetransmitmessages
1 = tx message list is generated from the tx list of each ECU. 0 = tx message list is generated from the rx list of each ECU.
tx
This is the collection of transmit messages sent by the simulator. It is dynamically created by the compile method.
replaystart
This starts the replay data file at the first value if the simulator is running.
replaystop
This stops file replay if it is running.
generatehvwakeup
If 1 the simulator will generate a single wire CAN high voltage wakeup when started.
mg
Accesses the collection of Messages for simulation. Messages are only present if they apply some custom properties such as default message bytes or period.
GenerateVNMF
If 1 the simulator will generate a VNMF for the single wire CAN ECUs involved in the simulation.
VNMFID
This indicates the CAN ID of the VNMF used by the simulator
ecu.sim.ec Object
Command Name
Description
Example
ecuname
The ECU short name.
enablenetworkmanagement
If 1 the simulator uses VN (virtual network) states to determine which messages should be sent. Otherwise, they are always sent.
key
networkname
The network name according to the uef file "hsCAN" or "swCAN".
ecu.sim.mg Object
databytes{X}
This allows default databytes to be entered for databytes0 through databytes7.
description
The description of the message. This includes the ECU name followed by a backslash.
"SDM\Airbag Indications"
disablemessage
This disables this message if 1.
overrideperiod
This will override the period of the message.
period
The modified message period if "overrideperiod" is 1.
