Dear all,
I am building a new TestStand sequence using a NI Switch Executive virtual device declared in NI MAX. One of the multiplexer used is the PXIe2576 with the 2-Wire Sixteen 4×1 Multiplexer topology. I would like to know if it is possible from NI Switch Executive to close a single relay instead of declaring a route. However, I need the 2-Wire Sixteen 4×1 Multiplexer topology to be kept. I have looked everywhere in NI Switch Executive and I cannot find this option. Also, I cannot use the basic NI Switch driver that can do that, as I want all my declarations in my NI Switch Executive file.
Thanks a lot in advance for your help !

If you want to maintain the topology then why override by closing a single relay? could you please elaborate more on what you would like to achieve?

Dear @santo_13,
I am replacing an old system. This system was able to run a huge number of sequences. However, this system was using LabVIEW as a sequencer and NI Switch driver. NI Switch Executive was not used and the MUX used were all SCXI. Now I use new MUX but with similar topologies and characteristics. In the old programs, sometimes the SCXI were initialized with a topology and sometimes not. For example sometimes the 2-Wire Sixteen 4×1 Multiplexer topology was used. And sometimes individual relay were activated, and it didn't cause a problem as the SCXI was re-initialized every time. Now with my NISE file, I cannot do that.
Thanks a lot for your prompt answer.
