Problem with application starting

PLCnext Technology & PLCnext Controls

Hello,
I am trying to run application from this article :
https://github.com/PLCnext/SampleRuntime/blob/master/getting-started/Part-03/README.md
after uploading Runtime app to my PLC I got this error:
28.06.24 12:34:33.634 Arp.System.Acf.Internal.ApplicationBase INFO - Application ‚ExternalIoProcess‘ was setup successfully.

I found this: https://www.plcnext-community.net/forum/#/discussion/2029/debug-arp-system-commons-invalidoperationexception
and I cannot edit the plcnext file and when i am trying to do this as sudo I got this message:
Sorry, user admin is not allowed to execute ‚/usr/bin/nano plcnext‘ as root on axcf2152

I have also removed all containers from plc.
Do you have any ideas why it is not working?
Thanks in advance

Hello Kacper,
I assume it the root cause is the process name: Please exchange „Runtime“ with „runtime“.
Explanation: The executable file is „runtime“:

target_link_libraries(runtime PRIVATE ArpDevice ArpProgramming
                     Arp.System.ModuleLib Arp.System.Module
                     Arp.Plc.AnsiC)
 ACF File: Process name is "runtime"
  <Component name="Arp.Plc.AnsiC" type="Arp::Plc::AnsiC::AnsiCComponent" library="Arp.Plc.AnsiC.Library" process="runtime">

I assume this line has a mistake:
scp bin/AXCF2152_22.0.4.144/Release/Runtime admin@192.168.1.10:~/projects/Runtime
Should be:
scp bin/AXCF2152_22.0.4.144/Release/runtime admin@192.168.1.10:~/projects/runtime

Please check. Thanks & BR Eduard

Hello,
I replaced this lines before but with “Runtime”, it looks like this in my project:

And also in source code of „PLCnextSampleRuntime.cpp“ :

if (ArpSystemModule_Load(„/usr/lib“, " runtime", strSettingsFile.c_str()) != 0)
{
syslog (LOG_ERR, „Could not load Arp System Module Application“);
return -1;
}

Thank you! Now its working
