Unable to set the signal using set_signal_value (I have added multiple databases) about py_canoe

[Dawalnk]

Is there any chance the signal value will not set because the multiple data bases available. ? Do I need to mention the data base name along with the message?

[Dawalnk]

Also I tried adding the single data base file as well,

The following code not setting the signal value to 7

from py_canoe import CANoe
from time import sleep as wait

canoe_init = CANoe()
************canoe open
************start measurement
sig_val = canoe_init.set_signal_value('CAN', 1,'ABC_1234', 'setValue',7)
print(sig_val)

Log:
2023-07-06 21:28:57,754 [CANOE_LOG] [INFO ] signal(CAN1.ABC_1234.setValue) value set to 7.
None

Please guide

CAN message should be accessible via CANoe network IL layer.
If the message is sent via CAPL or IG block then it is not possible to set the signal same via py_canoe.
It is a restriction from CANoe COM layer.
You can refer the example configuration available in this git repo for more info regarding simulation node.
Please post the sample configuration which you are facing failure. I will check and let u know the exact reason.

Hello @chaitu-ycr

Thank you for your response.

1. Do I need to make any special setting for CAN IL?
2. Is it possible to send the can messages with specific time frames? ex, 20ms,100ms , Cyclicmessage period 50ms etc...

Hello @chaitu-ycr

With reference to the attached image snap, I could able to see the engine ECU node and Light ECU node are"Canoe IL ...", While other nodes are "Prog..."

With modifications are your code I am able to send the diag requests and got responses also.
While unable to set the signal values. is it because the ECU node which I created is not "CANoe IL... " configured ?

How to change the prog node to Canoe IL... node?, Please guide how to create the CANoe IL ... node.
Using py_canoe the messages can be sent to real ECU's?

Thank you in-advance.

I am facing a similar issue, can you please guide on how to send can signal using Canoe IL Layer please ?

hi @Dawalnk and @raghavinti
step 1 is to make sure your dbc network ecu's support IL. for this please open your DBC and check below screenshot for reference.

step 2 is to check whether the node inserted in CANoe is using IL. check below screenshot for reference.

if your DBC network ECU not configured for IL, then you can set those values by yourself. check below screenshot for reference.

*Note: controlling messages via vector CANoe COM port is not possible. there is no CANoe COM function readily available from vector. sending message has to be always configured in CANoe config.
in future vector CANoe releases if vector provides option to control messages, i will update py_canoe package accordingly.
