So, how about it?: L MW0 //integer L 2 *I SLW 3 T MD10 L MW10 //integer OPN DB10 T DBW[MD10]

So, how to convert the code that I posted to TIA Portal in STL. This is my question... Best regards.

So, how to convert the code that I posted to TIA Portal in STL. This is my question... Hello, Have your tested those instructions in the editor? Try the followings for an S7-1500 and compile it.DB1 contains an array of 10 cells - real data type. [code] OPN "Data_block_1" //DB1 LAR1 P#0.0 L 5 lp: T #lp L 100.0 T DBD [ AR1 , P#0.0 ] +AR1 P#4.0 L #lp LOOP lp[/code] Best regards Hamid Hosseini

Berg Silver Member Joined: 1/17/2006 Last visit: 1/14/2025 Posts: 554 Rating: (29)	Pegaia TIP: Use DB with absolute address (non optimized). Hi. Where can I select this option in TIA V12 ? When I create a new DB this option is not available for me on the screen... I can only choose between FB, FC, OB, etc.. There isn't a check box with this option. thanks.

But before un-check read the following: Setting up block access STEP 7 Professional V12.0 (01/2013, English) wrote: Procedure To set the block access, proceed as follows: Open the "Program blocks" folder in the project tree. Right-click on the block whose block access you want to change. Select the "Properties" command in the shortcut menu. The properties dialog box of the block opens. Click "Attributes" in the area navigation. Enable or disable the "Optimized block access" option. Confirm your entries with "OK". What differences should you watch out for between optimized data storage and the standard type of block access in STEP 7 (TIA Portal) V12?
