1762-IA8 and 1762-IQ8 Input Image
For each input module, the input data file contains the current state of the
field input points. Bit positions 0 through 7 correspond to input terminals
0 through 7.
r = read only, x = not used, always at a 0 or OFF state
1762-IQ16 Input Image
For each input module, the input data file contains the current state of the
field input points. Bit positions 0 through 15 correspond to input
terminals 0 through 15.
r = read only
1762-OA8, 1762-OB8, and 1762-OW8 Output Image
For each output module, the output data file contains the
controller-directed state of the discrete output points. Bit positions 0
through 7 correspond to output terminals 0 through 7.
r/w = read and write, 0 = always at a 0 or OFF state
1762-OB16 and 1762-OW16 Output Image
For each output module, the output data file contains the
controller-directed state of the discrete output points. Bit positions 0
through 15 correspond to output terminals 0 through 15.
