The Industrial Raspberry Pi Forum

Hello,
I just gor a new revpi connect and I’m deploying a code I’m using on an old revpi. I’m using logi-rts both licensed and on the revpi connect (new is the 8GB, the old is the 4GB).
On the old revpi it works fine, while on the new one the same code does not work even if the deployment is ok from logicad.

In the shell, the service logi-rts reports this on the new device
Jan 10 15:43:32 RevPi31215 RTSLoader[3024]: TID76fa6000: RTS: Resource: activating initial code image "/opt/RTS/PLC/RTSCode.so"

Jan 10 15:43:32 RevPi31215 RTSLoader[3024]: TID76fa6000: RTS: Resource: Application Tasks started

Which I do not know what those can be.

In logicad then the variables cannot be read in the variables explorer and we see "Information for variable could not be determined". Though, it looks like the process is marked as "running" from logicad.
This is not due to the code as the exact same code works as expected on another device, so I suspect the current device is faulty (from a software or hardware point of view).

Thanks,
Mirko

Hello,
Any news? Otherwise we will consider returning the device and ask a refund for the device and the license.

Thanks

Hello,

Please try to get connected to te Revolution Pi with a console (e.g. Putty) and delete the PLC source files (RTSCode.so and RTSCode.bak) and try again deploying the code to this Revolution Pi.
Please also get sure, that the code file which you would like to deploy to the Revolution Pi has been created with the appropriate version of logi.CAD 3.
Please give us feedback if this operation has suceeded.

kind regards
Walter

I ran the following commands:
multiple times, and then deploy. Absolutely no luck though.

I'm using the logicad I downloaded from the kunbus website.

logi.CAD 3 compact
Version: 1.115.0

Maybe I was not clear on my first communication about this: We have 2 RevPi Connect (4Gb, old, and 8Gb, new); this is what happens:

• if I set the IP of 4Gb in RevolutionPi.ieplc and deploy, it works fine

• if I set the IP of 8Gb in RevolutionPi.ieplc and deploy, it does not work at all

Same code, same version of the engineering.

I just created a new project (which still works fine on 4Gb but it does not in 8Gb): the program has 1 USINT variable that is incremented every time till 35, when it is reset to 0.
You can download the test project from https://we.tl/t-vMwC8QaHVc (link valid till Jan 27th).

Do you have any debug steps I can follow? Or a test project I should try to upload on the device?

Let me know.

Thanks

Hello Walter,
"Please also get sure, that the code file which you would like to deploy to the Revolution Pi has been created with the appropriate version of logi.CAD 3."
so could it be that the root cause is the same like this issue:

Hello,
I verified that the old revpi has logicad 3.25, while the new one has 4.3. Now, should I revert to the old version on the new RevPi?
When will the new one be supported? Has we have some revpi around and since this was a major version update it might have a lot of new features and bugfixes.

Regards

Dear Mirko, could this problem be caused by the copied license? Because the license is bound to the crypto chip of each device. So you have to copy an invidual license to each device after cloning the image.

Dear Walter, please help us with this situation here. I have posted my thoughts but am not sure if I have hit the point or not. Thank you.

I never cloned the image.

Downgrading to the earlier version of the logi-rts package on the new RevPi did work.
Downloading form kunbus website https://revolution.kunbus.de/shop/en/logicad3 of the version 2.3 of logicad fails reliably after 1.07Gb (at least in the 7 trials i did before giving up) and the certificate of the website is not valid. Will Logicad 2.3 work with the latest log-rts package?

Hi mirko, sorry for the irritations. I am organizing a troubleshooting here with logi.cals.
