I ran into an issue that I can no longer start a session for labview bitfile. The python host interfaces with labview bitfile with write and read FIFOs. Python codes and errors are below. Same exact codes worked reliably until last week.
with Session("ccsdsbytecontrol_PXIe-7971R_CCSDSByteControl_nS419VaXs08.lvbitx", "PXI2Slot6") as session:
# Initialize FIFOs
write_fifo = session.fifos['Write_FIFO']
read_fifo = session.fifos['Read_FIFO']
write_fifo.start()
read_fifo.start()
Error happened with Session command:
