How do you store analog values?

Hello everyone,
I'm looking for a solution to store analog values that serve as reference points for temperature control. Currently, I store a temperature setpoint in an Av object and assign it a value in InitialValue, such as 12. The problem is that if an operator changes the value to 14, but I have to restart the PLC for maintenance, I lose the operator’s value, and the setpoint reverts to 12°C instead of 14°C.
I’ve looked into it, but I don’t understand how to do this. Could you please tell me how to do it and provide a short example?

Thank you!

Hi Latapoune,

You can use the the backup function. Configure the backup server with a Backup_Conf object and each value you want to backup with a Backup object.
