You can use the Routing and Faulting custom device in VeriStand with FIU modules such as the PXI-2510 to transition between defined states by changing the routing channels.
For example, when you transition from a state where ch0 is connected to dut0 (No Fault) to a state where busa is connected to dut0 (Short to Ground), the system performs the switching sequence automatically.
ch0
dut0
busa
First, the connection between ch0 and dut0 is disconnected, which opens the switch between these nodes. Then, the connection between busa and dut0 is established, closing the corresponding switch.
There is an approximate delay of 500 µs between disconnecting ch0–dut0 and establishing busa–dut0.
This behavior is the same when you connect busb to dut0 instead of busa.
