Vinhso Posts: 2 Rating: (0)	Pegaia Hi, to create a Standard DB in STEP 7 V12, create a DB as usual (add new, etc...). After created, right mouse click, properties, attribute and uncheck the option "optimized'. Why I can not uncheck optimized access option?

IBN-Service Posts: 8946 Rating: (1000)	Vinhso Why I can not uncheck optimized access option? Do you use V11? Than unchecking is not possible anymore, after DB was generated. You have to deselect the optimation bevor you save the DB firsttime.

Even if the bloc is brand new without any data configured or saved to it? The only option i found is to copy a DB from an older project underV11 that was using Absolute adressing and it keep the properties...I hope there is a better way to do that ?
