• In the system where the CPU module is
connected to the request destination device
over Ethernet, the request path and the
response path of IP packets differ.
• When multiple CC-Link IE modules with the
same network number are connected in a
multiple CPU system, the module mounted on
the lowest slot number is not set as a
controlled module that transfers IP packets.
• When multiple CC-Link IE modules with the
same network number are connected in a
single or multiple CPU system, the station
number of the module mounted on the lowest
slot number is not set as a relay station
number in routing parameter.
• Correct the routing parameter setting so that IP
packets use the same path for both request and
response transmission.
• When multiple CC-Link IE modules with the
same network number are connected in a
multiple CPU system, set the module mounted
on the lowest slot number as a controlled
module that transfers IP packets.
• When multiple CC-Link IE modules with the
same network number are connected in a single
or multiple CPU system, set the station number
of the module mounted on the lowest slot
number as a relay station number in routing
parameter.
