4-2-2 Preparation for Connecting Network
The following accessories are available for GX-series Digital I/O Slave Units, Analog I/O Slave Units,
and Encoder Input Slave Units.
Refer to "6-3-3 Communications Connectors" in Page 6 - 8 for information on the communications
cables for an IO-Link Master Unit.
Precautions for Correct Use
• The maximum cable length between connected nodes is 100 m. Note that some cables do not
guarantee 100 m. In general, if the conductors are strand wire, the transmission performance
will be lower than solid wire and the operation at 100-m distance cannot be guaranteed.
Confirm details with the cable manufacturer.
• When selecting connectors, check that the cables to be used conform to connectors. Items to
be checked include conductor size, conductor wire type (solid wire/twisted wire, 2/4 pairs), and
outer diameter.
We recommend cables with double, aluminum tape and braided shielding, taking noise
resistance into consideration.
