Step7 V5.5 Cross-reference not working in certain program blocks

Hello,

In one single project, 7 PLC are configured. Until recently, the cross reference is not working in two of the PLC program blocks.

From the error codes, I can refer to the S7 error codes and the remedy actions. Therefore the project reorganization is performed but it doesn't help much. 

Three screenshots are attached in this topic and I hope you can help to advise if there are other way to resolve this issue.

Thank you.

Hi,

reorganisation is not bad but I would use "Check Block Consitency" and then "Compile all".

This should work!

also very importany thing when adding data to middle if the data blocks

when ADDRESS has priority this will screw up all accesses.

when SYMBOL has priority do compile to update accesses.

I ALWAYS use 'Symbol has Priority' for Symbolic Programming

(to set priority right click on Blocks and click tab ADDRESS PRIORITY - see attached)

Your are right, but recompiling blocks should regenerate cross references in both cases...

Regards.
