No manuals yet. Hoping to see something in the new year. The units aren't officially released yet.

Then click on
Target and documentation package

That will take you to the package and the manuals.

We would have to look at your .pro file to see what is going on.

Thank you for the update. Good to know about the IP address.

Not sure why you are importing it. Make a project with both devices then add the network variables. I have multiple projects running with Network Variables. I have never run into an issue.

Do the same thing but just add another ECU. Then you will have to have a check mark next to Local Device since this will be coming from your PLC. You will have to take care that your task is 10 ms...

Go to the CR7xxS on our website (doesn't matter which country). Then click on the Downloads, then Important software downloads are available for this product

Just add the J1939 manager and ECU then add the signals you want to receive.389

No those are not available on 3.5. With 3.5 you get the J1939 Manager from Codesys.

I don't know why the website is not updated. That is managed by a different group that what manages the forum. I had already submitted this, hopefully it will be updated soon.

Please contact your local ifm support for items related to safety applications.

The only option is to use Maintenance Tool and do a Software/Commands/Force Bootloader Mode.

I don't know. I would have your local ifm representative remote into your PC to see what is going on there.

How many times do you scan? For me it never shows up on the first time. I usually have to scan a few times. Looks like you have everything setup correctly.

The scan only finds devices that...

What is the IP address of your PC? Did you change it to the same subnet? Also does your Codesys Target match the firmware on the PLC?

You are using the wrong libraries, no big deal.

You need to use the NT libraries, they are located here:
C:\Program Files (x86)\ifm electronic\CoDeSys V2.3\Targets\ifm\Library\ifm_J1939_NT

I wonder if the firmware is old enough that it doesn't support the Read Channel Parameters. This feature will not work if you do not have firmware on the PLC as well.

How old is the PLC? Can read the Identity?

Here is the CAN messages needed:
You simply need to send the 4 frames below to wake up the IO Module:

Bert,

You are correct, there isn't currently any manuals for the CR3114 libraries. This is being worked on.

You can not Group items on the CR0451 it is not supported.

Thanks,

Hi Bert,

Yes you can run higher than 250 hz, but if you look at the wave shape it is not symetrical.

ericci, please discuss this with your ifm Sales Person. There may be some options for you.

Sorry those units will not support tasks in Codesys V2.3.

Yes your application will be running all the time as fast as it possibly can.

Here is a step by step using the Download Tool.

When you implement the a J1939 ECU into your project you can see the status of the J1939 ECU in your code.

To monitor it you can use piece of code like this:

//J1939 status
xJ1939WatchDog :=...
