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.
f When 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.
f When 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.
DVP-PLC Operation Manual

Page 12
Ethernet Communication Module DVPEN01-SL
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
10
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.
DVP-PLC Operation Manual
Page 13
Ethernet Communication Module DVPEN01-SL
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” Æ 16-bit mode;
when the CR value is set as “1” Æ 8-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.

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.

5.2 Basic Settings
The basic settings include parameters as module name, language, enabling Modbus TCP and time
correction.
Setting up DVPEN01-SL basics
1. Module Name:
There can be many DVPEN01-SL modules in the network. Thus, you can set up a module name
for each module to identify the module when you need to use them.
2. Module Language:
You can select a language for each module name, and the windows will be displayed in the
selected language.
3. Enable Modbus TCP:
To enable or disable Modbus TCP. When Modbus TCP is disabled, WPLSoft will not be able to
upload or download.
4. Enable time correction:
DVPEN01-SL adopts NTP (Network Time protocol), which means it can acquire correct time
automatically from the time server in the network and correct the RTC in the MPU every fixed
period of time to ensure correct time in the MPU. The default setting of this function is “disable”.
5. Start Daylight Saving Time:
Daylight Saving Time; also known as summer time is a conventional local time adopted by many
countries in the world on a seasonal basis. Most commonly DST is obtained by adjusting the
official local time forward, by one hour, for the spring, summer, and early autumn periods.
Daylight Saving Time is not implemented in Taiwan; therefore, you do not need to check this
20
item.
6. Time Server:
IP address of the time server. You can acquire correct time from the time server to correct the
time in the MPU.

7. Time Zone:
time zone is a region of the Earth that has adopted the same standard time, usually referred to
as the local time. Most adjacent time zones are exactly one hour apart, and by convention
compute their local time as an offset from Greenwich Mean Time (see also UTC). Standard time
zones can be defined by geometrically subdividing the Earth's spheroid into 24 lunes
(wedge-shaped sections), bordered by meridians each 15° of longitude apart. The local time in
neighboring zones is then exactly one hour different. However, political and geographical
practicalities can result in irregularly shaped zones that follow political boundaries or that
change their time seasonally (as with daylight saving time), as well as being subject to
occasional redefinition as political conditions change. You should choice the Time zone that you
are.
5.3 Network Settings
The first step for all the network equipment to connect to the network is to have its own IP address (Internet
Protocol). The IP address is like a number for every network equipment to be identified in the network.
Setting up static IP of the PC
1. Enter Control Panel → Network Connection → click on “Local Area Connection”
2. You will see the “Local Area Connection Status” window. Click on “Properties”.

Setting up DVPEN01-SL Net work
1. IP configuration:
There are two types of IP, static IP and DHCP.
Static IP: Preset or manually modified by the user.
DHCP: Automatically updated by the server. There has to be a server in the LAN.
DHCP DHCP server offers the IP address, subnet mask and gateway.
2. IP address:
IP address is the location of the equipment in the network. Every equipment connected to the
network has to have an IP address. Incorrect IP address will result in connection failure on the
equipment or even other equipment. Ask your ISP for questions about IP address setup. The default
IP for DVPEN01-SL is 192.168.1.5.
3. Subnet mask:
Subnet mask is an important parameter for setting up the subnet, used for seeing if the destination
IP and the local equipment are in the same subnet. If not, the equipment will send the packet to the
gateway, and the gateway will send the packet to another subnet. Incorrect setting may cause the
IP Explanation
Static The user enters the IP address, subnet mask and gateway.
destination equipment unable to communicate with DVPEN01-SL. To see if your setting is correct,
conduct bitwise AND operations between your IP and subnet mask and destination IP and subnet
mask. If the two values obtained are the same, the two IPs are in the same subnet. The default
subnet mask of DVPEN01-SL is 255.255.255.0.
4. Gateway:
Gateway is the gate for two different subnets, allowing the two ends in different subnets to
communicate. For example, if the LAN has to be connected to WAN, it will need a gateway to bridge
the communication. The IP of the gateway has to be in the same subnet as DVPEN01-SL. The
default gateway IP address of DVPEN01-SL is 192.168.1.1.

5.4 Setting up E-Mails
E-mail is the abbreviation of electronic mail, which transmits mails through the network. DVPEN01-SL has
E-Mail functions for the user to pre-save a segment of text messages, which can be a descriptive message or
error message, into the subject of the E-Mail. When the E-Mail is triggered, DVPEN01-SL will send the
messages to the user by E-Mail.
DVPEN01-SL offers 4 sets of E-Mail information, and you can self-define the register or bit information to be
read. When the trigger occurs, DVPEN01-SL will add the set register or bit present value read to the E-Mail.
Every set of E-Mail information is able to contain maximum 100 continuous register data.
Setting up DVPEN01-SL mail
1. SMTP Server:
The E-Mail will first be sent to SMTP server, and SMTP server will send it to the designated
address. For example, assume there is an E-Mail to be sent to test@delta.com.tw
SMTP server is 172.16.144.121. The E-Mail will be sent to SMTP server first, and the server will
further send it to the recipient test@delta.com.tw
2. Subject of E-Mail:
You can enter text message in the column, and the message will be placed in the subject of the
E-Mail and sent to the recipient. DVPEN01-SL is able to contain 1 ~ 4 E-Mail subjects (max. 63
English characters are allowed).
You can select additional information for the E-Mail. Every set of E-Mail is able to contain 100
continuous addresses of registers.
3. E-Mail of Sender:
Maximum 63 English characters are allowed.
4. E-mail of Recipient:
You can enter 4 E-Mail addresses. One mail can be sent to 4 addresses (max. 63 English
characters are allowed).
, and the
.
24
5. Select recipients:
After you have set up all the parameters for the E-Mail, you will need to select recipients. The
DVP-PLC Operation Manual
Page 27
Ethernet Communication Module DVPEN01-SL
E-Mail will be sent to the designated recipients when the E-Mail is triggered. To trigger E-Mail, set
the value is CR#3 ~ CR#6 as “1”.
6. See “Application Examples Section 6.8” for more details.
Notes:
To correctly send out E-Mails, there has to be a SMTP server in the network. When we send out
an E-Mail, the mail will be sent to SMTP server first, and the server will further send the mail to the
designated address.
5.5 Data Exchange
DVPEN01-SL is able to designate a data exchange area for PLC MPUs to exchange and synchronize their
data.
Setting up DVPEN01-SL data exchange
1. Enable Data Exchange:
Check the box to enable or disable data exchange. Start data exchange after enable it.
2. Execute Mode:
You can set it to ”Always Enable” or ”Program Control”. When set to “Always Enable”,
DVPEN01-SL will execute data exchange continuously until the setting in DCISoft is changed.
When set to “Program Control”, DVPEN01-SL will execute data exchange according to the
program setting (CR#13 = 2: Execute; CR#13 = 0: Stop).
3. Communication Address & Data exchange host IP:
You have to enter the IP address of DVPEN01-SL at the other end. For example, if you would
like DVPEN01-SL to exchange data with 192.168.0.1, set No. 1 as 192.168.0.1. When the data
are being exchanged, if the value in CR#28 is H’0001, the data will be exchanged with
192.168.0.1.
4. Master Address & Slave address & Quantity.
Read (Å): Start address of the master’s receiving register Å Start address of the slave’s
sending register
Write (Æ): Start address of the master’s sending register Æ Start address of the slave’s
DVP-PLC Operation Manual
25
Page 28
Ethernet Communication Module DVPEN01-SL
receiving register
In data exchange, DVPEN01-SL will execute Write (Æ) first before Read (Å).
Quantity: A slave is able to send and receive at the same time maximum 100 consecutive data.
f For data exchange, D register is parted into 2 sections, D0000 ~ D4095 and D4096 ~ D9999.
Please DO NOT use different sections for the consecutive sent and received data (start
address + number of data).
5. See “Application Examples Section 6.11” for more details.
5.6 RTU
Use the “RTU” function to conduct mapping between Delta’s network modules DVPEN01-SL and
RTU-EN01.Set up the mapping information first, and you will be able to use WPLSoft in DVPEN01-SL to save
and retrieve the mapped bit (M) and register (D) in order to operate the remote RTU-EN01.
The settings
1. Enable Remote I/O Mapping:
Check the box to enable the remote I/O mapping. The mapping with remote RTU-EN01 will be
enabled according to the settings.
2. Communication Parameters:
Set up “Communication Timeout” (ms) and “Update Cycle” (ms) here.
3. PLC I/O Mapping:
Set up the start address of the mapped bit and analog register (RCR) of digital input (X) and
digital output (Y) on remoter RTU-EN01. The bit starts from M2000, and read/write register starts
from D2000/D3000. The software will automatically calculate the end address according to the
settings below.
4. Remote Device Mapping:
Check “Enable” and enter the remote RTU-EN01 ID (Slave ID), IP Address, number of digital
input points (RX), number of digital output points (RY), number of mapped read registers (Read)
and write register (Write).
DVPEN01-SL offers 4 slaves for mapping. Max. number of digital and analog points for mapping
26
DVP-PLC Operation Manual
Page 29
Ethernet Communication Module DVPEN01-SL
of every slave:
Digital I/O points (RX+RY): 256
Analog (Read) register: 64
Analog (Write) register: 64
5.7 IP Filter
IP filter is used for restricting the connection of the network in case some uncertain IP will cause errors. Only
the IP set within a certain range can establish a connection. Other IPs will be rejected.
Setting up IP filter
1. Enable IP Filter Function:
Check the box to enable IP filter.
2. IP:
IP addresses that are allowed to establish connections. Maximum 8 IPs are allowed.
3. Netmask:
The subnet of the IP is allowed to establish a connection. To see whether the destination IP is
allowed, conduct bitwise AND operations between the allowed IP and subnet mask and destination
IP and subnet mask. If the two values obtained are the same, the destination IP is allowed by the IP
filter. For example, assume the IP is 192.168.0.1 and subnet mask 255.255.255.255, the only one IP
allowed to establish a connection is 192.168.0.1. If the subnet mask is 255.255.255.0, the IPs
allowed to establish connections will become 192.168.0.0 ~ 192.168.0.255.
5.8 Static ARP Table
ARP (Address Resolution Protocol) is used for obtaining the MAC address corresponding to the IP address
in data transmission. For example, there is a datum to be sent to 172.16.155.250, but you do not know the
corresponding MAC address. You can use ARP to look up the MAC address by IP address, and the
corresponding MAC address will be saved, so you do not need to look it up again when sending the next datum.
DVP-PLC Operation Manual
27
Page 30
Ethernet Communication Module DVPEN01-SL
Therefore, if you do not know the MAC address, you will have to spend some time looking up the MAC address.
If you want to enhance the transmission efficiency, use static ARP table to save time. For example, assume IP:
192.168.0.1 and MAC: 00:14:22:56:0F:7F. As long as there are data sent to 192.168.0.1, you will get the MAC
address from the table.
Setting up static ARP table
1. IP:
Destination IP address in data transmission.
2. MAC:
The MAC addresses corresponding to the IP address.
Note:
Incorrect settings may result in connection failure. Therefore, DO NOT set the MAC address of
the equipment without the network into the table.
5.9 Setting up Password
To prevent the set values in DVPEN01-SL from being modified, you can set up password to lock the settings
in DVPEN01-SL.

Note:
After the password is locked, all the pages cannot be set up unless you unlock the password.
However, if you set up DVPEN01-SL by RS-232, you can return the setting to default setting
whether the password is locked or not. For example, if you have locked DVPEN01-SL but forget
the password, you have to return DVPEN01-SL to factory default setting by RS-232, and all the
settings will return to default ones.
5.10 Returning to Default Setting

Explanations:
• The data exchange will be executed every one second.
• Write the IP address of PLC_A into CR#117 and CR#118. The first two IP codes (192.168 =
H’C0A8) should be written into CR#118, and the last two IP codes (0.4 = H’0004) into CR#117.
• Set CR#111 as “1” to enable the 8-bit mode. The Modbus instruction is stored in the low byte of
CR#120 ~ CR#247.
• Write Modbus instruction into CR#120 ~ CR#125. CR#120 is the Modbus address.
• Write the length of the instruction into CR#119.
• Write “1” into CR#115 to start the execution of Modbus TCP instruction.
• CR#116 = 2 refers to successful execution. CR#116 = 3 refers to failed execution.
• If the execution is successful, Y0 on PLC_A will go between On and Off every one second.

Explanations:
1. Enable mapping: CR15 = 1
2. Disable mapping: CR15 = 0
3. Once CR#15 is enabled, M2000 ~M2009 and D2000 ~ D2009 will read the data, and M3000 ~ M3009
and D3000 ~ D3009 will read the present value before starting to write.
4. During the execution of mapping, other devices are not allowed to modify the value in the mapped
register.
