(1) Do not connect or disconnect the Communications Unit's communica-
tions cable while the network is operating. Short-circuits or poor contacts
in the cable may prevent normal communications.
(2) Be sure that the power supplies for the Communications Unit, Slice I/O
Units connected to the Communications Unit, and external I/O are wired
correctly through the Communications Unit's terminal block.
Connect the first Slice I/O Unit to the Communications Unit by aligning the
sides of the Units and sliding in the Slice I/O Unit from the front. Additional
Slice I/O Units can be connected consecutively to the first.
In the following example, a Slice I/O Unit is being connected to a DeviceNet
Communications Unit.
Slide the Slice I/O Unit toward the DIN Track from
the front. Insert the Unit until you hear a click,
which indicates that the Unit has locked on the Track.
It is not normally necessary to release the DIN Track
mounting hook when mounting the Unit.
Do not touch the connector on the Unit's base block.
Slide Slice I/O Units in from
the front to install.
Slice I/O Units (64 max.)
