easiest and fastest solution is to wrap the data in a structure and write/read this struct data as bin file:
fbFileWrite_Inst(
sNetId:= '',
hFile:= Filehandle,
pWriteBuff:= ADR(ProduktDaten),
cbWriteLen:= SIZEOF(ProduktDaten),
bExecute:= TRUE,
tTimeout:= T#5s,
bBusy=> ,
bError=> ,
nErrId=> udiFileWriteErrorId,
cbWrite=> udicbWrite);

Yes, I know about CAA File and I can write wrapper for my task.
But it's not the simplest deal.
So I hope to find ready solution.
CmpSettings seems like exactly what I need, but I can't see a way to use it for custom files (only for CODESYSControl.cfg)

I can't understand the reason - I think, it will be fine to add input sFile to functions of this lib.

I do something similar to what you describe.
My HMI with Codesys Soft PLC doesn't have user memory to save persistent variables.
So I save the value of the variable but not the name in a text file and load it when the system boots. It works great.

To do this I use the CAA.File library

https://help.codesys.com/webapp/idx-CAA_FILE-lib;product=CAA_FILE;version=3.5.15.0

The included code examples help a lot.

Hi.
I need to write/read simple settings files with content like NAME=VALUE.
I know about Recipe Manager, CAA File etc. - so I can solve it with different methods.
But I want to try find ready simple solution.

I check CmpSettings, but seems like it works only with CODESYSControl.cfg.
Is this a way to use it for my files?

I also check CAA Settings, but seems like it's not implemented in runtime.

Or maybe I missed some another lib?
