When an EtherNet/IP Unit and Contact Output Unit are mounted in the same Controller, communica-
tions errors may occur due to the noise that is generated by the contact outputs. Take either of the fol-
lowing countermeasures.
Separating the Units
Separate the EtherNet/IP Unit as far as possible from the Contact Output Units.
Separating the Cables
Separate the twisted-pair cable that is connected to the EtherNet/ IP Unit as far as possible from the
wiring to the Contact Output Units.
