Communications from
an external device
an external device
Device data can be read or written from an external device to a
module on the network where the Ethernet adapter module is
connected. Data also can be read or written from/to the Ethernet
adapter module.

Communications from
a CPU module
(on-demand function)
a CPU module
(on-demand function)
Issuing a send request from the CPU module to the Ethernet
adapter module allows data to be sent to the external device.
Events such as link start instruction and read instruction can be
notified to an external device.
In addition, data can be simultaneously sent to all the external
devices on Ethernet where the Ethernet adapter module is also
connected (broadcast communications).

Communication using the specified IP
address over CC-Link IE Field Network
(IP packet transfer function)
address over CC-Link IE Field Network
(IP packet transfer function)
With this function, communications using the specified IP address
can be performed over CC-Link IE Field Network. For example, a
personal computer connected to the Ethernet part can
communicate with another personal computer connected to a Built-
in Ethernet port QCPU.
Two networks of CC-Link IE Field Network and Ethernet are not
required, resulting in reduced wiring cost.
