The installation package does not include those files. However, you should be able to get them from

https://github.com/NREL/EnergyPlus/tr... ( The files in question are_ExternalInterface-functionalmockupunit-to-actuator.idf, _ExternalInterface-functionalmockupunit-to-schedule.idf, _ExternalInterface-functionalmockupunit-to-variable.idf).

Since the IDF files of the development branch may differ from the E+ version you are currently using, I suggest to use the files as pointers so you know how to implement the objects in your own IDF file.

The ExternalInterfacesApplicationGuide along with the InputOutputReference and the aformentioned IDF files should be sufficient to get you up to speed so you can set-up a co-simulation example.

If you are still encountering issues, then let me know so I can post a working example file for E+ 9.1.

The one which uses the Schedule object can be found here

Hello Dr. Nouidui, thank you for your help. Now I can realize the co-simulation using the fmu files in EP package. However, I have another quick question that how can I export a new fmu from Dymola which can be co-simulated in EP. Are there any tools or manuals?

Hello Dr. Nouidui. I was wondering if you could also include the Modelica model that the FMU came from. Thank you.
