Overview of DeviceNet Section 1-1
Note The front-panel indicators and other parts of Analog Input Units, Analog Out-
put Units, and Counter Units differ from those of other I/O Units. These Units
belong to a group called Special I/O Units.
One I/O Unit Connecting Cable (cable length 40 mm) is included with each I/O
Unit. One end connector is attached to the Communications Unit.
I/O Unit Connecting Cables with a cable lengths of 0.1, 0.3, 0.4, 0.6, and 1 m
(GCN1-010/030/040/060/100) are sold separately (see below).
Note For details on MULTIPLE I/O TERMINAL Units, refer to the DeviceNet (Com-
poBus/D) MULTIPLE I/O TERMINAL Operation Manual (W348).
