Python API data retrieval of voltage and current related to dummy bus after in-line fault of SCMU

The PSSE I am using is ver.34. I have tried the code psspy.scbus2(999999,"VPOS") and psspy.scbrn2(ibus,999999,ickt,"IPOS"). Both show the ierr = 2 which the bus 999999 is not found. I have also tried the bus code 99999, it does not work either.

Please let me know your thought and solution. Thank you.

I have came across similar error before, Before calling scbus2 or scbrn2, you need to initialize the short-circuit data retrieval APIs using scinit()

If this was already taken care of, then the error maybe because of syntax error or the bus may not be part of the system

Syntax for V35 is : This API routine was first introduced in release 28.0.0. Python command syntax: ierr = scinit() Please crosscheck manual for V34 version

Thank you for your reply! Yes, I have already used the scinit, and it works fine for other buses with scbus2 and scbrn2. However, when it comes to the dummy bus (i.e. bus id 999999), error was raised and stated that the bus does not exist.
