I am using Output:Variable (report output variables from E+ to external interface) and ExternalInterface:Schedule (getting schedule data from external interface)

I have tried editing the .idf file variable but I get this error. What else should I change in order to change the timestep of data exchange?

When you use the Output:Variable, set the time step to 'timestep', e.g., Output:Variable,*,Zone Mean Air Temperature,timestep;

Make sure the EnergyPlus and the Ptolemy are using the same time step, e.g., 600s per time step: In EnergyPlus, Timestep,6; In Ptolemy, SDF Diector, set period = 600 (or refer to a parameter), and set the iterations = number of total time steps.
