I/O Points
The values shown on the I/O Points Properties page are the raw values at the I/O objects and may not match values
shown on status displays that are affected by control program logic.
i-Vu® users logged in as Power User and above are able to edit various parameters associated with the input channels and
the display names for all channels.
We strongly recommend that you leave these parameters at their defaults. The RTU Open is not a programmable controller.
I/O can only be used for the purpose designed in the equipment control program. Modifying these parameters may result
in unpredictable equipment control.
See Wiring inputs and outputs (page 13) for more information. This table lists each of the I/O Channels, their functions,
associated hardware, and terminal numbers.
