I have created a DB "DateTime" for time management via the HMI. So, the user enters the desired startup date and time for automatic machine startup. As shown in the screenshot below, the default value of the "DateTime" function is : "1970-01-01-00:00:00". I'd like to change the default year from 1970 to 2024. Is this possible ? Is it possible to change the year directly via the HMI ? Best regards, Gabriel Attachment DB DateTime.PNG (257 Downloads)

	If this Information really helps, you could use the Rate function Best Regards, JBS98

Also yo might want to retain the value, so that last entered time is always the starting point..
