In Codesys help it says: In case of a shutdown of the controller or after “Reset” (warm / cold / origin) the data is stored automatically if the parameter xSaveOnChange is not set.
What if don't want to save automatically?
Is it possible to disable this feature?

then probably the persistence manager is not the right feature/tool, if you do not want have a persistent state on shutdown..!
you may use: https://store.codesys.com/ini-file-utility-bundle.html
If you just need save some parameter on demand and restore them on demand.

My controller uses Codesys 3.5.12 so now that the INI file utility is part of the IOT library and requires V3.5.14.0.
Can I still use the 1.0.0.1 of the INI file utility or not available anymore?
What options do I have?

Not possible.
I have 3 HMI devices from different manufacturers using Codesys runtime versions 3.5.12, 3.5.10 and 3.5.7.
So I will have to wait for years until the manufacturers decide to update their runtime to a version that can be used with the version 3.5.14.0 of IOT library.
It's real problem with many libraries available in Codesys store.
My HMI doesn't not have not volatile memory to save Codesys persistent variables and I didn't knew about the Persistent manager at the time I was creating my application. I couldn't use the INI file utility so basically I had write my own simple version of configuration file utility that can used to save user parameters (more than 300 values in 3 text files) on demand and restore them during the first PLC cycle.

Hi,
you must use the Persistent Manager, please follow this PDF.
Keep in mind that you cannot write files to the EMMC continuously, so put a interval time at least of 30 seconds.
Hi, I cannot seem to get a beaglebone to retain any variables. Can anyone help as to how to get this to work?
more posts ...
Hi,
try to follow this guide on how to set the persistence manager from scratch, it worked for us.
The persistence manager allows cyclic and on change saving of the variables.
Is it possible to activate saving in application instead of using the aforementioned ways?

I guess you could trigger the save from application by using:
PersistenceManager.INST_<channelname>.ExternalSave()</channelname>
I guess some thing like this should work
I don't understand the following part.

not available (..the license)
update the device?
