(1)CompoBus/S Terminals
The following CompoBus/S terminals are provided: CompoBus/S communications data high/low
terminals, NC terminals for communications power supply plus (+) and minus (-), and an NC ter-
minal. (Power is supplied internally for this Unit, so the NC terminals for communications power
supply can be used as relay terminals.)
(2)DIP Switch
Used to specify the node number for the CompoBus/S I/O Link Unit.
(3)LED Indicators
Used to show the CompoBus/S communications status.
(4)Expansion I/O Connecting Cable
Connected to the expansion connector of a CP1E CPU Unit or an Expansion Unit or Expansion
I/O Unit. The cable is provided with the CompoBus/S I/O Link Unit and cannot be removed.
Precautions for Safe Use
Do not touch the cables during operation. Static electricity may cause operating errors.
(5)Expansion Connector
Used to connect Expansion Units or Expansion I/O Units.
