I/O Memory Mapping

Addressing
The addressing scheme for 1762-OX6I is shown below.
Output Data File (0)
Output (O) File
(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.
Output Data File
Relay outputs are controlled using the bit positions in Word 0, as follows:
• 1 = relay energized (normally-open contact ON)
• 0 = relay not energized (normally-closed contact ON)
For each module, the output data file contains the controller-directed state of the
discrete output points. Bit positions 0 through 5 correspond to output points 0
through 5.
