1-10 I/O Configuration
1769-IQ6XOW4 Input Image
For each module, the input data file contains the current state of the field
input points. Bit positions 0 through 5 correspond to input terminals 0
through 5, bits 6 through 15 are not used.
r = read, x = not used, always at a 0 or OFF state
1769-IQ6XOW4 Output Image
For each module, the output data file contains the current state of the
control program’s directed state of the discrete output points. Bit positions
0 through 3 correspond to output terminals 0 through 3, bits 4 through 15
are not used.
r/w = read and write, x = not used, always at a 0 or OFF state
1769-OA8, 1769-OW8, and 1769-OW8I Output Image
For each module, the output data file contains the current state of the
control program’s directed state of the discrete output points. Bit positions
0 through 7 correspond to output terminals 0 through 7, bits 8 through 15
are not used.
r/w = read and write, x = not used, always at a 0 or OFF state
1769-OB16, 1769-OB16P and 1769-OV16 Output Image
For each module, the output data file contains the current state of the
control program’s directed state of the discrete output points. Bit positions
0 through 15 correspond to output terminals 0 through 15.
