Hi 

I have some problem to convert S7-1500 program blocks to s7-300/400 program blocks

I copy s7-1500 program blocks, and then That blocks move to s7-300/400 program blocks

so This message show that The property "Optimized block access" is not supported in s7-300/400 modules

If you know solution this problem , Please tell me solution

Thank you! 

Hello,

in S7-300/400 isn't permitted optimized block access, so if there is some access to Data Block which is in previous S7-1500 created with Optimized access Attribute, this is probably error. Solution can be in SW S7-1500 disable on data blocks attribute Optimized access, precompile and then again will try convert

Edit: but I will wait for probably other errors

hi worker,

maybe this FAQ´s may help you to understand optimized block-access:

What types of access, value columns and operator input options are available for the global data blocks in STEP 7 (TIA Portal) V12?

What differences should you watch out for between optimized data storage and the standard type of block access in STEP 7 (TIA Portal)?

hope this helps,

regards,

Thank you so much! Duris

I solve this problem

but I'don't understand that you will wait for other error

what's that mean? :D

Thank you! Jeff casagrande

I'm good to see your screen shot and then I solve this problem

 That would defeat the purpose of a public forum.  If you have questions, more than likely others will have the same one.

The complier should do this automatically.

To check, right-click the DataBlock, select Properties - Attributes.  There should be a box for Optimized Access, which should be unchecked.

Alright!

but Attributes exist check-box which don't un-check

what can I do ? :D
