Error in S7

When I try to go into a LAD/STLFBD: Program blocks

I got a pop-up windows with text:

There is a time stamp conflict with at least one block call.



Anybody?

It means that the block you opened has called a function or function block with time stamp confilict which means the called block has been changed and the calling block is not updated. The time stamp conflict block is coloured in red. So in S7 for example if OB1 calls FB1,DB1 if FB1 or DB1 changes you should update the block call in OB1. You can do it several different ways:
1) delete the old block and call the new block
2) Right click on old block call and click update block call
There should be another way but couldnt rememeber it now...

Thnx for quick respons !

I will try this!
