1-1 MULTIPLE I/O TERMINAL
1-1-1 Overview
A MULTIPLE I/O TERMINAL is a building-block DeviceNet Slave that consists
of a Communications Unit that interfaces one or more I/O Units. The I/O Unit
interface supports up to 8 I/O Units and a total of up to 1,024 I/O points. I/O
Units are connected using simple snap-on connections via I/O Unit Connect-
ing Cables. Allocation and address settings on the I/O Unit interface are not
required, enabling simple, flexible distributed I/O control.
