Parameter Discussion
wait determines if the function should poll the Status Register on the module until either the
module is ready or timeout is reached. If the module is not ready by timeout, NI-DAQ returns
a timeout error.
1: The function will poll the Status Register on the module, until ready or timeout.
0: The function will read and return the Status Register on the module.
data contains the contents of the Status Register.
0: Indicates that the module is busy. Do not perform any further operations on the
modules until the status bit goes high again. This value means the SCXI-1122 or
SCXI-1160 relays are still switching or the SCXI-1124 DACs are still settling.
