Have you compared FC2 with FC2 in the PLC?
Is it the same?
Is FC2 actually used within the program?

i agree with moggie, do a compare with the cpu.
And the call function wont work like that, you need something to call like another FC or a FB. And you do not use "end call".

That is what shows up when there is no function that was called. Check if there is this REAL_TO_WORD function in your blocks folder.
