Noise Reduction when Using Contact Outputs
Communications errors can occur when Contact Output Units are mounted to
the same Rack or connected to the same PLC as an FL-net Unit due to noise
generated by the contact outputs. Use one or more of the following measures
when installing Contact Output Units and Ethernet Units on the same Rack.
Mounting Location
Mount (or connect) any Contact Output Units as far away from the FL-net Unit
as possible.
Cable Location
Separate the transceiver cable or twisted-pair cable connecting the FL-net
Unit as far from the wiring to the Contact Output Units as possible. The coax-
ial cable must also be placed as far away from the Contact Output Units and
their wiring as possible.
