On-board remote I/O scanner ports are available on all PLC-5 controllers.
On-board extended-local I/O scanner ports are available on some PLC-5
controllers. On-board ControlNet ports are available on some PLC-5
controllers. To provide a DeviceNet I/O scanner port to the system, you must
add a 1771-SDN DeviceNet Scanner Module.
