1Introduction
1. Thank you for choosing Delta DVPDNET-SL. To ensure correct installation and operation of DVPDNET-SL,
please read this chapter carefully before using your DVPDNET-SL.
2. DVPDNET-SL running on the left side of PLC can serve as the DeviceNet master or slave with PLC MPU
together. It can be configured through DeviceNet software.
1.1 Features
Serves as DeviceNet master by connecting to the PLC and supports standard DeviceNet protocol.
DeviceNet Builder provides convenient graphic configuration interface; automatically scans and
recognizes all slaves in the bus.
Supports DeviceNet Master and Slave modes.
Supports eight types of baud rates: 10 kbps, 20 kbps, 50 kbps, 125 kbps, 250 kbps, 500 kbps, 800kbps,
1M kbps
1.2 Basic Functions of DVPDNET-SL
DVPDNET-SL DeviceNet Network Scanner can be used both as a master or a slave on the DeviceNet
network. When being used as a master, it supports following functions:
Automatically carrying out the data exchange with PLC MPU. User needs only to operate the special
register in PLC to realize the monitoring of all slaves.
Supports client function of explicit message.
Supports slave to establish all kinds of I/O connections: polled, bit-strobed, change of state and cyclic.
As the connection medium between DeviceNet Builder configuration software and DeviceNet network.
The configuration software is able to directly configure the network through DVPDNET-SL.
Sending explicit messages for reading/writing the data in slave through PLC ladder diagrams.
Max length for output data and input data are both 380 bytes.
When being used as a slave, it supports the following functions:
Explicit message serve and Group 2 only serve connection mode.
Automatically exchanging data with the PLC. The user needs only to edit the D register in the PLC
without using FROM/TO instruction.
Polling
Max lengths for output data and input data are both 255 bytes.

4Configuration of DVPDNET-SL
4.1 Configuration through DeviceNet Builder Software
Before DVPDNET-SL starts to work, it must be configured through DeviceNet Builder software.
Note:
Different PLC corresponds to different device addresses. For details, please refer to Input and Output
Mapping Areas in Section 4.2. We take DVP-SV as the PLC for description below.
4.1.1 Selection of Communication Channel
Max 8 DVPDNET-SL modules can be connected to the left side of the PLC and every DVPDNET-SL is a
communication channel. When there are three DVPDNET-SL modules connected to PLC’s left side and
DeviceNet Builder software is online, the following dialog box will pop up for selecting the current channel.
Parameter Explanation
Unit No.
The unit No. of the first DVPDNET-SL (DNET Scanner) on the left side of PLC is 1.
PLC’s left side can be connected with max 8 DVPDNET_SL. The further
DVPDNET-S is from the PLC, the larger its unit No is.
Name DVPDNET-SL’s name in DeviceNet Builder software.
Code
For displaying the current mode of DVPDNET-SL: master mode or slave mode.
Input
mapping
The register areas which PLC MPU distributes to DVPDNET-SL. The areas are
mainly used to receive the message from DeviceNet Slaves and the data from
slaves on the bus will be automatically updated to these registers.
Output
mapping
The register areas which the PLC has assigned to DVPDNET-SL. The areas are
mainly used to control DeviceNet slave and the control data in these registers will
be automatically sent to DeviceNet slave in the bus. Slave will take some action
accordingly after receiving the data.

4.1.2 Setup of Scan Module
The following dialog is for setting DVPDNET-SL’s current mode: master mode or slave mode.
Parameter Explanation
Master mode For setting DVPDNET-SL as master.
Scan interval time
The cycle time for master to send and receive the real time data
after real-time data connection is successful.
Expected Packet Rate
The result value of the parameter multiplied by 4 is the timeout time.
(Unit: ms)
Master assumes that the slave is offline if it receives no response
from slave after the timeout time is elapsed.
Extension baud rate
The parameter is effective only when DVPDNET is in master mode.
Selecting “Enable” activates the function.
Select an appropriate baud rate according to actual demand.
Slave mode For setting DVPDNET-SL as slave
Bit-strobed Reserved; no actual purpose now.
Polled
The parameter is effective only when DVPDNET is in slave mode.
The filled byte numbers correspond to the data length of outputs and
inputs as DVPDNET-S is in slave mode. “TxSize” corresponds to
“Output length” and “RxSize” corresponds to “Input length”.
Change of State/Cyclic Reserved; no actual purpose now.

5Sending Explicit Message from Ladder Diagram
DVPDNET-SL supports the sending of explicit messages through WPL programs.
Note:
Different PLC corresponds to different device addresses. For details, please refer to Input and Output
Mapping Areas in Section 4.2. We take DVP-SV as the PLC for description below.


①: The PLC sends the explicit request message based on WPL program to DVPDNET-SL.
②: Then DVPDNET-SL transfers the request message to the target equipment.
③: The target equipment processes the request message and replies with a response message to
DVPDNET-SL.
④: The PLC stores the response message from DVPDNET-SL to D register to finish one explicit message
transmission.

5.2 Structure of Explicit Message
You can edit explicit messages in “explicit request message editing area” and “explicit response message
editing area”. See the table below for the corresponding relation between the two areas and PLC devices. If
you transmit the request message to be sent out to D6250 ~ D6281, DVPDNET-SL will fill the response
message data to D6000 ~ D6031.
PLC device Mapping area Mapping length
D6000 ~ D6031 Explicit response message editing area 64 bytes
D6250 ~ D6281 Explicit request message editing area 64 bytes

Command: Fixed to “01Hex”.
ReqID: The request ID. Whenever an explicit message is sent out, the message will be given a ReqID
for DVPDNET-SL to identify every message. For the next explicit message to be sent out, you have to
change the ID. ReqID = 0 indicates that DVPDNET-SL will not send out any explicit message. Range
of ReqID: 00Hex ~ FFHex.
Size: The length of the message, starting from D6253. The high bytes of D6255 are reserved. When
the data length is being calculated, D6255 is counted as 1 byte. The maximum data length is 58 bytes.
Errors will occur when the length is longer than 58 bytes. Unit: byte.
Port: The communication port. Fixed to “00Hex".
MAC ID: The node address of the target equipment on DeviceNet.
Service Code: The service code of the explicit message. See the meanings of the codes in the table
below:
Service Code Explanation
01Hex Read all attributes (Get_Attribute_All)
02Hex Set up all attributes (Set_Attribute_All)
0EHex Read a single attribute (Get_Attribute_Single)
10Hex Set up a single attribute (Set_Attribute_Single)
