7.12.5 Connecting I/O Device via FL-net
The expansion unit FCU8-EX568 functions as a node of FL-net. Connect the FL-net-compatible equipment with an
ethernet cable (category 5e or above and twisted pair shield cable).
(Note 1) FL-net expansion unit is equipped with two RJ-45 connectors (LAN1 and LAN2); however, the function of FL-
net is available only on LAN1. Do not connect any cable to LAN2 port.
[Noise countermeasures of ethernet cable]
When the FL-net expansion unit is being used, expose the cable by removing a part of the cable sheath and make
sure to use the shield clamp for the exogenous noise countermeasure.
When you cannot use the shield clamp, make sure to install a ferrite core as a substitute to ethernet cable (near the
expansion unit).
