*8: The Ethernet port of a built-in Ethernet port QCPU cannot be accessed.
*9: The Ethernet port of a built-in Ethernet port QCPU and an Ethernet module can be accessed.
*10: UDP (MELSOFT Connection) must be added to the open setting of a built-in Ethernet port for the
access target CPU.
*11: For Q24DHCCPU-V, the system Ethernet port (S CH1) can be accessed.
*12: For Q12DCCPU-V, setting to allow MELSOFT Connection in the open setting of the built-in
Ethernet port is required.

........ The control CPU of the high speed data logger module and
the network module must be set to QCPU (Q mode).
Access target CPU
.. For accessible programmable controller CPUs, refer to the
following table.
*1: The control CPU of the access target network module must be set to QCPU (Q mode).
*2: When the control CPU of the access target network module is a C Controller module, only the
control CPU of the network module can be accessed.
