CANNY logic forum → CANNY 5.2 / 7.2 duo → My diagram is not working
I try to connect Canny device with the machine.
I made the connection Can0 with the ECU and Can01 with the vehicle.
I made a diagram that change the value of IDL 0x0A32.
put contact on, i get errors that Ecu not is actief.
Wat can be the problem.
Map send with email.

have a question about 120 ohm termination resistor in canny 7 duo.
Saterday i dit a test on a machine but it not works, canny send no data in the canbus. I read that the 120 ohm termination resistor have to be enabled if the can speed is 500 kbps. My canbus speed is 250 kbps. If i have to enable the120 ohm termination resistor , is on Can0 or Can01?
I made a diagram that change the value of IDL 0x0A32.
I can't see the CAN Gateway Selector 0 Mask Setup Register, CAN IDL on your diagram.
And do you sure about your CAN Gateway Selector 0 Drop Mode Enable Register value?

Thx for the info.
In the manual I not find mutch info for the use of the resistors.
I wil check my diagram send send it back .

canny 7 duo now works on the canbus.
I try now with a simple map: disable the retransmision.
In my cantrace is have Canid: 0x18FEBF03.
IDL will be F03 (if i m correct)
Canny not block the messages.
I think then that the IDL is wrong.
cantrace.JPG 230.26 kb, 12 downloads since 2024-06-15
the protocol is J1939 with 29 bit Canid.
Have i to use the Can ERL in my diagram?

No, you are not. Please see description of the "CAN Gateway Selector X Value Setup Register, CAN IDL" her https://cannylogic.com/docs/c72duo/cangateway/
the protocol is J1939 with 29 bit Canid
Please read all information related to extended format in the article at that link.
i try to build a simple diagram.
can id: 0x18FEF103 - extended format.
IDH=18FE
IDL=F103
ERL=8008
I want to change D0:D1 with value 20 (dec)
On the simulator i see no fault, but not works on the machine.
Can you check wat is wrong?

This is finally correct register's values for some applications. However, you did not indicate the full names of the registers.
Can you check wat is wrong?
You did not attach a diagram and didn't ask a specific question. I just can’t "check" whatever that means because I don’t know what “wrong” means in your case.
Sorry,
i try to understand the logic in building of a diagram.
I think that I mis somme important settings in my diagram.
maybe i have to search for "Canlogic for dummys" :-)

Looks like you almost made it!
Please see the attachment for the diagram, slightly corrected to my taste.
Please check that you have connected CAN0 to the source of the original messages and CAN1 to the receiver of the modified messages. Check that the CAN termination is correct. If after all it doesn’t work as it should, then message logs from both CAN interfaces will be required for further diagnostic.

Thx for the support.
I have to learn mutch more.
i dit 1 correction, green light to can1 request to send.
if my diagram i made is now correct then =
canid: 0x18FEF103 (extended format)
Change value D1:D0 to 20 (Dec)
Send to Can 1
-Do i have to change Bit?

i dit 1 correction, green light to can1 request to send.
Why? This is completely wrong.
Do i have to change Bit?
What Bit?
Why? This is completely wrong.
What is wrong?
d' ont i have to use the "Can1 request to send" ?
To send the modify bits to Can1?
In my previous map the output was "Green light",so i think no data will be send to Can1.
What Bit?
D0:D1 are the value that i want to change. (speedometer)
Konstatin,
I find this map on the russian forum.
The map is to change the speedometer with modify bit D1:D0.
Can you control of this can work?

Taking ready-made examples and modifying them to solve your problems is a good way to learn a new product.
However, this is only true if you have read the documentation beforehand and understand what exactly you are changing and what effect these changes will have.
A necessary addition to this method is repeated analysis and rechecking of the modifications made, as well as constant monitoring of the operation of the modified example in hardware after each modification using measuring instruments, data loggers, etc.
This way you will be able to observe what effects your changes lead to, even if you did not read the documentation carefully enough or made a mistake when changing the example.
The most useless thing you can do in terms of gaining new knowledge is to ask someone else to do all this work for you.
If your goal is not to learn how to work with controllers, measuring devices and documentation, but to get a ready-made working circuit, then all I can advise you is to create a new topic here: https://forum.cannylogic.com/viewforum.php?id=11 and wait for a response if someone answers you.
And yes, you made a mistake, at least here:

Yes my goal is to learn more of controllers. If this controller works , i wil need more controllers.
wat i d ont understand is how to see the faults in my diagram that i make. Diagram check is ok, simulator is ok.
I change the fault from 0x800F to 0x8008. But still the bytes that i want to change not change.
I try to learn from the faults that i make :-)

Diagram check is ok, simulator is ok.
Just because a diagram doesn't have formal errors doesn't mean it does exactly what you need. The simulator will help debug the logic, but not the interaction with the Firmware drivers. Please read this topic carefully: https://cannylogic.com/docs/cannylab/si … escription

Exactly as I told you before:
A necessary addition to this method is repeated analysis and rechecking of the modifications made, as well as constant monitoring of the operation of the modified example in hardware after each modification using measuring instruments, data loggers, etc.
And regarding this:
But still the bytes that i want to change not change.
Where is the data on which you made this conclusion? As I told you before:
Please check that you have connected CAN0 to the source of the original messages and CAN1 to the receiver of the modified messages. Check that the CAN termination is correct. If after all it doesn’t work as it should, then message logs from both CAN interfaces will be required for further diagnostic.
Finaly it works !
My simple test diagram works.
With datalogger is see the bits is changend.
only the speedometer not use the new bits.
Is it nessecary that i put in the diagram that every Xms the candata send?

My simple test diagram works.
Your simple test diagram not only works, it sends junk messages with ID 0x000 and no data to CAN1 every time it receives a message with ID 0x18FEF103 or 0x18FEB103 on CAN0.
This happens because you throw registers on the diagram following some logic of your own instead of studying the documentation.
konstatin,
i try a simple diagram to block the ID:0x18FEBF03
even this not works wiht my cannyduo.
i dont now what can be wrong.
all the connectors are good can0 , can1
what i experience is that sometimes i get canbus faults. then if i trun of the power en start again the fault is gone. weird

Try this. And check the termination twice.
