Summary:
I upgraded a project from V4 to V5 and since then when I run my project it reports "Memory failure at Address Ox2127000 of Board 'Board1'"

I am using a KTX card to talk to my Allen Bradley PLC.  Each time I run the project the address of the memory failure changes.  Please explain.

 

Solution:
The driver cannot access the memory on your communications board.  Different memory locations would be accessed each time you project is run hence the different messages.  So when you get this message it is likely that the board is not there, has a bad connection in the PC or there is a problem in its setup.
