Hello,
Unfortunately for RT users, NI-Switch is an IVI based driver. IVI, and therefore NI-Switch, has never been supported and will not work in RT.
The good news is it is possible to control the switches in the SCXI-1161 using NI-DAQ digital calls. This is the method you must use in order to use the SCXI-1161 in an RT system.
There is an example called, "SCXI-1161 Digital Output.vi" that ships with NI-DAQ and should be viewable in the NI Example Finder catagorized under Hardware Input and Output -> Traditional DAQ -> SCXI.
