1 Introduction
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
z
Serves as DeviceNet master by connecting to PLC MPU and Supports standard DeviceNet protocol.
z DeviceNet Builder provides convenient graphic configuration interface; automatically scans and
recognizes all slaves in the bus.
z
z
Supports DeviceNet Master mode and Slave mode.
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
¾
DVPDNET-SL DeviceNet Network Scanner can be used both as a master or a slave in DeviceNet. When
being used as a master, it supports the following functions:
z
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.
z
z
z
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.
z

When being used as a slave, it supports the following functions:
z
z
z
z
Explicit message serve and Group 2 only serve connection mode.
Polling
Offering 256 bytes for input data and 256 bytes for output data in data exchange with master.
Automatically exchanging data with PLC MPU. The user needs only to edit the D register in the PLC
without using FROM/TO instruction.
z Max length for output data and input data are both 255 bytes.

②: DVPDNET-SL sends out request message to the target equipment.
③: The target equipment processes the request message and responds DVPDNET-SL.
④: DVP-SV MPU stores the response message from DVPDNET-SL to D register. One explicit message
transmission is therefore completed.

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 to D6000 ~ D6031.

DVPDNET-SL can only send out 1 explicit message at a time.
Before sending explicit message by using WPL program, we suggest you clear the request message

If the slave responds with standard error code, and DVPDNET-SL also consider the communication
being successful, “The communication of explicit message is successful.” will indicate that the
communication has been completed successfully.

6 Bit-Strobe Command
6.1 Principle of Bit-Strobe
Bit-strobe is one of the standard I/O transmission methods for DeviceNet. The length of command is fixed to 8
bytes (i.e. 64 bits), and every bit corresponds to a slave.

When b0 of D6282 = 0, the node 0 equipment will be selected, and it will need to respond with a message to
the master. When b0 and b1 of D6282 = 0, the node 0 and node 1 equipment will be selected, and they will be

In the bit-strobe mode, the master will not send control data to the slave node. However, when its
corresponding bit is set to 0, the slave node will have to respond with I/O data to the master. When its
corresponding bit is set to 1, the slave node will not have to respond with I/O data to the master.

7 Display of Node Status on Network
7.1 Display of Node Status in Scan List
This function is to monitor if DeviceNet slave is offline or not. DVPDNET-SL does read-time monitoring to the
nodes in the scan list and maps the status of every node to a bit. You can acquire the node status by
monitoring D6032 ~ D6035. See the table below for the corresponding relation between PLC devices and the
nodes on the network:

When the node in the scan list is normal, the corresponding bit will be off. If the node occurs with abnormality,
its corresponding bit will be On.
7.2 Status of DVPDNET-SL
You can acquire the real-time status of DVPDNET-SL by monitoring D6036. When DVPDNET-SL runs
normally, D6036 = 0. When DVPDNET-SL is being initialized, the high byte of D6036 = 1 and the low byte = 0.
When error occurs in DVPDNET-SL, the high byte of D6036 = 2. For detailed error information, please refer
to the error codes, i.e. the low byte of D6036.

8 Setup of Slave Mode
DVPDNET-SL can serve as slave through modifying of the mode by software. As DVPDNET-SL serves as slave,
the default input / output data length is 8 bytes and max input / output data length is 255 bytes.
DVPDNET-SL can be set as slave mode in the following method.
1) Connect the devices according to below figure. PC accesses PLC MPU via RS232 or RS485.
