While I open FB411 made some modification and closed it. After if I again open the same FB411 and tried to save it then it gives below error and shows RED line in declaration table.

"The block can not be saved because the declaration tablecontains invalid entries"

Please see attached piicture for more info.... 

Hello,

Yes FB918 is available in Program

 Have you tried the option check and update access

Yes I have tried it but no luck. I have renamed for STAT0 as well but same error.

 Hello,

and if you delete the row then save and reinsert new row ?

The program seems to be uploaded from the PLC. Then parts of the program were modified.

The big problem seems to be that some modifications have been made to the FB918 or functions that modify the FB918 interfaces. First you need to open FB918 and just save it, to confirm that the function is OK internally. If not, try the "Check and update access". Then you need to close and reopen the FB411 and right click on the FB918 call and select "update block call". Pay attention to the screen that appears and if it's ok, press OK. Check that the updated FB918 call is OK.
