Allen-Bradley ControlLogix Ethernet Driver Help
is necessary for the driver to correctly address the I/O. To address the I/O in a particular slot, all slots up
to and including that slot must be configured with I/O. For example, if a user is only interested in the I/O
in slot 3, the I/O for slots 1 and 2 must be configured.
