1. This includes Universal Remote I/O and DeviceNet I/O.
2. This does not include DeviceNet I/O.
3. This type of I/O in this control system requires a seperate I/O scanner installed in an I/O module slot.
4. These are not on-board ports. They are available only thru an interface.
5. Only some have on-board EtherNet/IP ports. But all have the capability to have an EtherNet/IP port added thru an interface.
