A DINT datalink is sent across RIO as 2, 16 bit intergers. There is no DINT datatype in the SLC, so to read the data we will copy the
DINT into 2, 16 bit intergers.
N11:114 = LSW Datalink A2 Out from RIO BT Read
N11:115 = MSW Datalink A2 Out from RIO BT Read
N13:114 = LSW Datalink A2 Out
N13:115 = MSW Datalink A2 Out

A DINT datalink is sent across RIO as 2, 16 bit intergers. There is no DINT datatype in the SLC, so to write the data we use 2, 16 bit
intergers in the SLC.
N13:14 = LSW Datalink A2 In
N13:15 = MSW Datalink A2 In
N10:14 = LSW Datalink A2 in for RIO BT Write
N10:15 = MSW Datalink A2 in for RIO BT Write

A floating point datalink is sent across RIO as 2, 16 bit intergers. To read a floating point datalink correctly in the SLC, you must first
swap the high and low 16 bit intergers, and then copy the 2, intergers into a floating point address.
N11:112 = LSW Datalink A1 Out from RIO BT Read
N11:111 = MSW Datalink A1 Out from RIO BT Read
N13:112 = MSW Datalink A1 Out
N13:113 = LSW Datalink A1 Out
N12:5 = Datalink A1 Out
