Reading Back-up State Rung
You can read the back-up state of the DeviceNet scanner with a single
rung of ladder logic. The back-up state is useful for debug or more
sophisticated back-up schemes. The message in this rung uses the
SINT data type.
Figure shows the rung you can use to read the back-up state.
