
Receive Length
: Sets the length of data received by the local CPU module. The length must be between 0–512
bytes.

Keep Alive Timer
: Sets a maximum time to keep the connection alive. If no data is transmitted, and the keep alive
period has elapsed, the CPU module automatically terminates the connection.
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 you store the sent data cannot overlap the devices where you store the received data. If the IP
address of the remote device is 192.168.1.100, the port number used by the remote device is 65500, the port number
used by the local CPU module is 65501, and the remote device and the local CPU module can transmit data through
this TCP connection.
If the local CPU module sends 10-word data to the remote device, the data is stored in D0–D9 before the data is sent.
If the local CPU module receives 20-word data from the remote device, the data is stored in D100–D119.
If the length of data received is larger than the setting value for the length, the first 20 words of data are stored in
D100–D119, and the remainder of the data is discarded. Likewise, if the length of data received is less than the setting
value for the length, the data is stored in the devices starting from D100, and the values in devices where no new data
is stored are unchanged.
If no data is transmitted, and 60 seconds have elapsed, the CPU module closes the socket and terminates the
connection.
In the
RTU-EN01 Mapping
table, you can set a Delta RTU-EN01 slave in connection with a DVP-ES3/EX3/SV3/SX3
Series module. The remote device is controlled through Ethernet and you can connect up to 4 groups of RTU-EN01 in
the network. Refer to the operation manual for setting and operation of RTU-EN01.
Select RTU Mapping Enable checkbox to enable the function of connection between RTU module and
DVP-ES3/EX3/SV3/SX3 Series module. Set the update cycle in
Cycle
box and a timeout in
Timeout
box. It means a
timeout when RTU does not give a reply within the timeout set.
The data mapping between each group of RTU-EN01 DVP-ES3/EX3/SV3/SX3 Series module is set in the
RTU
Mapping
section. RTU-EN01 and I/O module connected to it are set via DCISoft. For more information on DCISoft,
refer to the operation manual.
