(4) Expansion I/O Connecting Cable
Connected to the expansion connector of a CP1L-EL/EM CPU Unit or a
Expansion Unit or Expansion I/O Unit. The cable is provided with the
CompoBus/S I/O Link Unit and cannot be removed.
Note 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.
Connect the Unit.
Determine the node
address of the
CompoBus/S I/O Link Unit
and set the DIP switch.
Wire the CompoBus/S
transmission path.
CompoBus/S I/O Link Units are connected to the CP1L-EL/EM CPU Unit. For
CP1L EM-type CPU Units, up to three Units can be connected, including any
other Expansion Units and Expansion I/O Units. The Units can be connected
in any order from the CPU Unit. For CP1L EL-type CPU Units, one Unit can
be connected.
