[TRNSYS-users] Type 56 Time Step

I am trying to run the simulation with a time step of less than 1 hr. I am getting an Range check error from trnsys. On further investigation I found that the error was coming from Type 56.
The simulation runs fine with a time step of 1 hr with no errors at all.
Further the time at which the error occurred followed a pattern.
Time step 1 min - Error in the beginning
Time step 3 min - Error at *.05 Hr
Time step 6 min - Error at *.1 Hr
Time step 9 min - Error in the beginning
Time step 12 min - Error at *.2 Hr
Time step 15 min - Error at *.25 Hr
Where * is any hour depending on the startime of the simulation.
e.g When the start time was 0 min, read * as 23.
Also when the error occurred in the beginning(time step 0,9 min) the listing file had and error
" The wall timebase must be an integer multiple of the simulation timestep'
I set the timebase to 1 in the BUIEdit's Output window as is recommended in the manual.
On debugging from type56 I found that one source of error was due to and array related to the building schedules getting out of bound. Particularly it was from the function
Line 4203 of Open_TYPE56.for
For the time step of 1 min and 9 min the error occurred at the line
I have no clue about why this is happening, can anyone please help me out with this.
