Init vs Boot tasks
According to help:
Boot task is executed only once at PLC start up.
Init task executed at each download of the application and on starting up the system (after Boot).
I cannot fully understand how to pick the right place for some tasks, can anyone tell when to use one or the other with a simple example? I am missing the point.

As example
Use Init task if you want to be sure that a value has an proper initial value after transfering the application.
As example EEPROM values used in the sample project for alarm history.
Use Boot taks if you want to be sure that a value has a proper initial value after every start of the PLC .
As example flexible inital values which are aligned to EEPROM parameters.

Hi @otrotabi ,
You can use the Boot or Init Task to set some parameters when the PLC boots up this can be good for example in case there are some parameters of the machine that work fine and you have a "BackUp" in the controller and you just need to power cycle the equipment to go to the "Working state", Another use of those task is to set some configuration of the PLC.
More info about the Tasks can be found in the next presentation (but you already know the content inside);
