I got the same error when I tried to create a new project from scratch (S7-1500). This does not happen with the s7-1200 template and I guess is a problem of how the FC-1500 is programmed.

If you download the v15/v16 template and change the addresses of the configured modules, or just remove them, you will get the same error.
