How to run Python-scripts on the ctrlX CORE

By installing the Python app, the interpreter stays present on the ctrlX-CORE.
Since the functionality had been upgraded and its interfaces changed incompatible - latest created script files (maybe Tiger-generated form promoter-package) are not executable anymore. The attached Interpreter description will offer the info needed to update the former script coding.

The upcoming script-manager-functionality/app is supposed to provide an easy and intuitive way to place and execute scripts on the ctrlX-CORE. Meanwhile we need to get familiar with interims solution.
Goal of the paper is to get familiar with the script-handling-workaround, which will be dispensable soon.   

How to place the script file(s) on the ctrlX?

Transfer the script files using the Configuration interface.


a) Use the Configuration-Website to download the config to the PC.
b) Unzip and add the python script file(s) and zip again.

c) Create a new/empty configuration by clicking + and upload the modified zip file.
d) The prepared configuration gets active by clicking the Hook-button – which registers the *py file(s) at the Ubuntu OS
(do not care about the storage location – you may not find easily viewing with SSH/MobaXterm).

How to execute the scripts using Rest-clients e.g. Yarc

e) Get the authentification token first


f) Create a new script instance by sending a similar Rest-payload.


g) Finally the script can be started by sending the payload containing path and filename of the related script.

with the payload:

Re: How to run Python-scripts on the ctrlX CORE

I tried to do this and sucessfully created an instance under script but when I send the post request to cmd/file of the instance with the file path I got the error "DL_CREATION_FAILED" with code 404. I am trying this on a virtual CORE and I saw with ssh that in the directory "/var/snap/rexroth-automationcore/common/solutions" I do not have a directory of "activeConfiguration", in my case this directory is completely empty even though I did active my configuration. I saw that my added script file was stored in the "/var/snap/rexroth-solutions/common/solutions/activeConfiguration" directory. But even when I try this path as the pay load I still get the same error.

Re: How to run Python-scripts on the ctrlX CORE


the Failure 404 assume that the 'URL-Path' is not correct.
Assuming you added as well the Authorization Token in the https Rrequest do run the script (that mistake is related to Failure 401),
I want you to check the typing please.




I just tried it with the ctrlX CORE virtual and it worked fine. I guess you included the 'AuthentifcationToken' as well in the 2nd https request to run the script file.



Please return if the info did not help to solve the topic.

Re: How to run Python-scripts on the ctrlX CORE

Hello, colleague;

I am very intereasting in python with ctrlX. I have already installed the python app in my virtual controller.

some guys show me a example write by python,

the first line is " import Datalayer"

when I try to import Datalayer, it will throw out "ModuleNotFoundError".

Is this module have already installed in the Virtal control?  Or should I do something special seeting?

Thank you very much!python_no_module.png
