Labeling the Terminals
A write-on label is provided with the module. Mark the identification of each terminal with
permanent ink, and slide the label back into the door.
1762 Expansion I/O Addressing
The addressing scheme for 1762 Expansion I/O is represented in the following figure.
Input Data File
For each module, slot x, words 0 and 1 contain the analog output module status data for use in
the control program.
The bits are defined as follows:
• SOx = General status bits for output channels 0…3. This bit is set when an error (over- or
under-range) exists for that channel, or there is a general module hardware error.
• OOx = Over-range flag bits for output channels 0…3. These bits indicate an input signal
above the user range and can be used in the control program for error detection. The
module continues to convert analog data to the maximum full range value while this bit
is set (1). The bit is reset (0) when the error clears.

(1) I/O located on the controller (embedded I/O) is slot 0. I/O added to the controller (expansion I/O) begins with slot 1.
