Where: I = Digital input
O = Digital output
AI = Analog Input Channel (channel 0 = AI0; channel 1 = AI1)
AO = Analog Output Channel (channel 0 = AO0; channel 1 = AO1)
ST = Analog Input Channel Status (channel 0 = ST0; channel 1 = ST1) (0 = no error; 1 = fault)
CM = Calibration mode (0 = run; 1 = calibration mode)
LA = Low alarm (0 = no error; 1 = fault)
LLA = Low low alarm (0 = no error; 1 = fault)
HA = High alarm (0 = no error; 1 = fault)
HHA = High high alarm (0 = no error; 1 = fault)
UR = Underrange (0 = no error; 1 = fault)
OR = Overrange (0 = no error; 1 = fault)
LC = Low clamp (0 = no error; 1 = fault)
HC = High clamp (0 = no error; 1 = fault)
OW = Analog output open wire (OW0 = channel 0; OW1 = channel 1)
OFLT = Output fault on one or more outputs in a group (OFLT0 = group 0; OFLT1 = group 1)
Rsvd = Reserved
