On PG5 2.1 the 'fatal error 2004' is shown after building a project where a smart RIO PCD3.T665/T666 is used.

FAQ #101871

 

Problem:
After building a PG5 2.1 project which does include smart RIO Network the error message
"Fatal Error 2004: File specified more than once: Device1.obj" appears.



Reason:
This error occurs if one of the program files of the smart RIO manager does have the same name as the smart RIO manager. (On the picture above 'Device1')

Solution:
The name of the smart RIO manager and the names of the program files of the smart RIO manager have to be different.
-> Change either the name of the smart RIO manager or do change the name of the program file of the smart RIO manager so that they are different.
