services. Up to 16 can be used at a time, and they

Ethernet Unit can thus simultaneously execute the
FINS communications service by TCP with up to 16
remote nodes.
Use IP address
to protect When this option is selected, if the Ethernet Unit is

Select this option to prevent faulty operation (by
FINS commands) from specific nodes from affecting
the PLC.
