upload function blocks

It was neccesary to reset a S5-155U (cpu946/947) and upload the program. Al program uploads exept function blocks for COM535, FB120S SEND/FB121S RECEIVE/FB126S SEND-A/FB127S REC-A. These FB are very large. When uploading I get the error "AG Zeit uberlauf". Is there some trix to upload these FB's.
