(1) The I/O Link consists of one master and multiple slaves.
Master: CNC (such as Series 30i-A)
Slaves: I/O Unit-MODEL A, Power Mate, operator's panel
connection unit, and other devices
(2) Up to 16 groups of slaves can be connected to one I/O Link.
Group numbers 0 to 15 are sequentially assigned. Number 0 is
assigned to the group nearest to the master.
The number of connected slaves in a group differs depending on
the types of slaves.

consist of slaves of the same type, however.
