Warning
3 Please read this instruction carefully before use and follow this instruction to operate the device in order to prevent damages
on the device or injuries to staff.
3 Switch off the power before wiring.
3 RTU-DNET is an OPEN TYPE device and therefore should be installed in an enclosure free of airborne dust, humidity, electric
shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key or specific tools
are required for operating the enclosure) in case danger and damage on the device may occur.
3 RTU-DNET is to be used for controlling the operating machine and equipment. In order not to damage it, only qualified
professional staff familiar with the structure and operation of RTU-DNET can install, operate, wire and maintain it.
3 DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check all the
wirings again before switching on the power and DO NOT touch any terminal when the power is switched on. Make sure the
ground terminal is correctly grounded in order to prevent electromagnetic interference.

DVP-PLC Operation Manual 3
1 Introduction
Thank you for choosing DVPEN01-SL module. To correctly install and operate DVPEN01-SL, please read
the manual carefully before using the module.
DVPEN01-SL is an Ethernet communication module for remote setting and communication through
WPLSoft. DVPEN01-SL is able to send E-mails, automatically correct the RTC in DVP28SV11R/T and
exchange data. It supports Modbus TCP communication protocol and can conduct remote monitoring by using
SCADA (Supervisor Control and Data Acquisition) software or HMI (Human Machine Interfaces). DVPEN01-SL
can be the master of Modbus TCP, sending out Modbus TCP instructions and controlling the peripheral
equipment. In addition, under MDI/MDI-X auto-detection, it does not need to use a crossing cable. See the
contents below for more detailed instructions on DVPEN01-SL module.

CR#9 ~ 12: E-Mail 1 ~ 4 Additional Message
Explanations:
The user fills in the code, and the code will be stored in the title of the E-Mail and sent out with the
E-Mail.
Data Exchange
CR#13: Data Exchange Trigger
Explanations:
When the CR is set as “0”, the data in data exchange area will not be transmitted. When the CR is
set as “1”, the data in data exchange area will be transmitted.
fWhen the Execute Mode in the software is set to “Program Control” (See 5.5), set CR#13 to 2,
and the data exchange will continue to execute. Set CR#13 to 0 to stop the data exchange.
fWhen the Execute Mode in the software is set to “Always Enable”, the data exchange will
continue to execute whatever the setting in CR#13 is.
(Firmware V2.0 and later versions support continuous execution of data exchange.)
CR#14: Data Exchange Status
Explanations:
When the CR is set as “0”, the data have not yet been received. When the CR is set as “1”, the
data exchange is in progress. When the CR is set as “2”, the data exchange is successful. When
the CR is set as “3”, the data exchange fails.

Ethernet Communication Module DVPEN01-SL
DVP-PLC Operation Manual
10
CR value Status
0 Data have not yet been received.
1 Data exchange is in progress.
2 Data exchange is successful.
3 Data exchange fails.
CR#25, 26: Destination IP
Explanations:
To set up the Slave IP address for data exchange manually, write “0” into CR#28 first before
setting up the destination IP. For example, if the user wants to set the destination IP address to
192.168.0.2, write H’0002 to CR#25 and H’C0A8 to CR#26. (K192 = H’C0, K168 = H’A8, K0 =
H’00, K2 = H’02).
CR#28: Destination Slave ID
Explanations:
When you set up the Salve ID (i.e. K1 ~ K255) for data exchange, DVPEN01-SL will
automatically search for the corresponding IP address from the Slave IP list. For example, if the
ID is set as “0”, the value in CR#25 and #26 will be regarded as the destination IP.
CR#29 ~ 48: Data Transmission Buffer
Explanations:
Storing the data to be transmitted to the remote MPU.
CR#49 ~ 68: Data Receiving Buffer
Explanations:
Storing the data received from the remote MPU.
CR#81: Read Address for Data Exchange
Explanations:
Setting up manually the Modbus address of the register for Slave data exchange. Only register
address is allowed (e.g. D0 = H’1000).
CR#82: Read Length for Data Exchange
Explanations:
The number of receiving registers (K1 ~ K100) in data exchange.

Ethernet Communication Module DVPEN01-SL
DVP-PLC Operation Manual 11
CR#83: Read Length for Data Exchange
Explanations:
Setting up the Modbus address of the register for Master data exchange.
CR#84: Written-in Address for Data Exchange
Explanations:
Setting up manually the Modbus address of the register for Slave data exchange.
CR#85: Written-in Address for Data Exchange
Explanations:
The number of transmission registers (K1 ~ K100) in data exchange.
CR#86: Transmission Address for Data Exchange
Explanations:
1. Setting up the Modbus address of the register for Master data exchange.
2. Example: Write H’1000 (D0) into CR#81, K1 into CR#82, and H’1064 (D100) into CR#83. If
the data exchange is successful, the value in D0 of the Slave will be written into D100 of the
MPU. Or write H’1002 (D2) into CR#84, K4 into CR#85, and H’1008 (D8) into CR#86. If the
data exchange is successful, the value in D8 ~ D11 of the Master will be written into D2 ~ D5
of the Slave. Both sending and receiving can be executed at the same time. When the values
in CR#82 and #85 are both “0”, DVPEN01-SL will use the default registers (CR#29 ~ CR#68)
and number of registers (K20).
Sending Modbus TCP Instruction
CR#111: 8-bit Processing Mode
Explanations:
Setting up the Modbus TCP transmission mode. When the CR value is set as “0” Æ16-bit mode;
when the CR value is set as “1” Æ8-bit mode.
CR#112: Modbus Client Keep-Alive Time-out
Explanations:
CR#112 is the TCP Keep-Alive time-out for Modbus TCP connection (s). Default: 30s. If the
connection idle time becomes longer than the keep-alive time-out, DVPEN01-SL will cut off the
idle connection.

Ethernet Communication Module DVPEN01-SL
DVP-PLC Operation Manual
12
CR#114: Modbus TCP Time-Out
Explanations:
Setting up the communication time-out (in ms) for Modbus TCP mode.
CR#115: Modbus TCP Trigger
Explanations:
When the CR value is set as “1”, Modbus TCP will be triggered. After the data transmission is
completed in Modbus TCP mode, the CR value will automatically be reset to “0”. Please trigger
by differential instructions.
CR#116: Modbus TCP Status
Explanations:
Displaying the current communication status of Modbus TCP mode. When the CR value is set
as”0” Æthe data have not yet been received; when the CR value is set as “1” Æthe data
exchange is in progress; when the CR value is set as “2” Æthe data exchange is successful;
when the CR value is set as “3” Æthe data exchange fails.
CR value Data exchange status
0 The data have not been received.
1 The data exchange is in progress.
2 The data exchange is successful.
3 The data exchange fails.
CR#117, 118: Modbus TCP Destination IP
Explanations:
Setting up the destination IP address in Modbus TCP mode. See explanations on CR#70 and
#71 for how to set.
CR#119: Modbus TCP Data Length
Explanations:
Setting up the length of communication data in Modbus TCP mode. Length for 8-bit mode: K1
~K100; length for 16-bit mode: K1 ~ K200.
CR#120 ~ 219: Modbus TCP Data Buffer
Explanations:
Buffer for transmitted/received data in Modbus TCP mode.

b0 The network is not yet connected.
b1 Incorrect IP setting
b2 CR#13 is set as “transmitting data”, but the data exchange
is forbidden.
b3 CR#13 is set as “transmitting data”, but the data exchange
mode has not yet been enabled.
b4 NTP-Server connection fails.
b7 SMTP-Server connection fails.
b8 DHCP has not obtained the correct network parameter.
RTU Mapping
CR#15:Enabling Flag for RTU Mapping
Explanations:
1: Enable; 0: Disable. Default = 0
Firmware V2.0 and later versions support RTU mapping.
CR#16: Connection Status of RTU Mapping Slave
Explanations:
b3 ~ b0 display the connection status of RTU slave. The connection may encounter some
problems when any of the bits becomes 0. Firmware V2.0 and later versions support RTU
mapping.
b0: Status of RTU slave 1
b1: Status of RTU slave 2
b2: Status of RTU slave 3
b3: Status of RTU slave 4
4.3 Numbering of Left-Side Modules
After DVPEN01-SL is installed properly, you need to compile the PLC program to control the special I/O
module. PLC offers FROM instruction (for reading) and TO instruction (for writing) to control the control registers
(CR) in the special I/O module.
Numbering of the modules: Every special I/O module connected to PLC MPU has a No. to allow you to know
which module is which when compiling the PLC program. The first special I/O module attached at the left hand
side of the PLC MPU is numbered as K100, the second as K101, the third K102, and so on.
