 Remote IP: Users can set a remote IP address.
 Remote Port: Users can set a communication port used by the remote device for this TCP connection.
The port number must be within the range between 0 and 65535.
 Local Port: Users can set a communication port used by the local CPU module for this connection. The
port number must be within the range between 0 and 65535.
 Send Address: Uses can set the initial device in the CPU module where data which will be sent is stored.
 Send Length: Users can set the length of data which will be sent by the local CPU module. The length
must be within the range between 0 and 4096 words.*
 Receive Address: Uses can set an initial device in the CPU module where data which will be received is
stored.
 Receive Length: Users can set the length of data which will be received by the local CPU module. The
length must be within the range between 0 and 4096 words. *
 Keep Alive Timer: Users can set a maximum keep alive time for the connection. If no data is transmitted,
and the keep alive period has elapsed, the CPU module will terminate the connection automatically.

* For AHCPU5x1-EN (FW V2.03 or later) and AHCPU560-EN2 (FW V1.10 or later), the supported length is
4096 words at most. For previous firmware versions and AHCPU5x0, the supported length is 500 words at most.
You can use change the DDF version in HWCONFIG to have a bigger range.
The port number used by the local CPU module and the port number used by the remote device cannot be the
same, and the devices where data which will be sent is stored cannot overlap the devices where data which will
be received is stored. If the IP address of the remote device is 192.168.1.100, the port number used by the
remote device is 65500, and the port number used by the local CPU module is 65501, the remote device and
the local CPU module can transmit data through this TCP connection.
If the local CPU module wants to send 10-word data to the remote device, the data will be stored in D0~D9
before the data is sent. If the local CPU module receives 20-word data from the remote device, the data will be
stored in D100~D119.
