DeviceNet Network Scanner DVPDNET-SL
Warning
ꢀ 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.
ꢀ Switch off the power before wiring.
ꢀ DVPDNET-SL 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.
ꢀ DVPDNET-SL 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 DVPDNET-SL can install, operate, wire
and maintain it.
ꢀ 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.

Introduction
1. To ensure correct installation and operation of DVPDNET-SL, please read this chapter carefully before using
your DVPDNET-SL.
2. This chapter only provides introductory information on DVPDNET-SL. For more detailed information on
DeviceNet protocol, please refer to relevant references or literatures.
3. DVPDNET-SL is a DeviceNet master module operating on the left side of DVP-SV series PLC MPU. When
DVP-SV is connected to DeviceNet through DVPDNET-SL, DVPDNET-SL will serve as the data exchange
interface between DVP-SV and other slaves on the bus. DVPDNET-SL is in charge of sending the data in
DVP-SV to the slaves on the bus, and at the same time collecting the data returned from each slave and
sending them back to DVP-SV.

Basic Functions of DVPDNET-SL
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
z
Client function of explicit message.
All kinds of I/O connections established between the slave: polled, bit-strobed, change of state and
cyclic.

As the connection interface between DeviceNetBuilder 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.
Automatically exchanging data with PLC MPU. The user needs only to edit the D register in the PLC
without using FROM/TO instruction. When connected to DVP-SV/DVP-EH2-L MPU, registers after
D6000 will be adopted temporarily.

I/O Scan List
Item
Explanation
Software screen
Before DVPDNET-SL starts its operation, you
have to configure its scan list through the
configuration software. The scan list is a list
consisting of the information of slave devices with
data, e.g. slave address, I/O type, I/O data length
and so on, to be exchanged with DVPDNET-SL.
DVPDNET-SL is responsible for managing the
slave devices in the scan list, establishing
connections and exchanging I/O data with them.
DVPDNET-SL will not establish connections and
exchange I/O data with slave devices which are
not configured in the network.
Scan
Table
DVPDNET-SL provides an Input Table (380
bytes) and an Output Table (380 bytes) for the
data exchange with slaves. When a slave device is
configured into the scan list, the software will
automatically allocate a I/O data exchange are of
corresponding length to the slave from the
mapping table. The I/O table is the data exchange
interface between the PLC MPU and the slave
I/O Table device. It corresponds the I/O data in the D
register of the MPU with the I/O data in the slave.
After you configure the network, download the
configured data to DVPDNET-SL, and it will start
the I/O data exchange with the corresponding
slave device according to the configured data
received. Data in Output Table will be sent to the
salve, and data returned from the slave will be
filled into Input Table.

Constructing DeviceNet Network
In this section, we will present an application example, illustrating how to construct a DeviceNet network and
the configuration of the network. Before constructing a network, you have to first know clearly what the network
is for and start a preliminary planning for the data to be exchanged. The plan shall include the maximum
communication distance, slaves to be used, total length of data to be exchanged and so on. These information
will decide whether the network you construct is a reasonable one, or if it satisfies your needs, and even affect
the later-on network sustainability and flexibility of network capacity upgrade.

①: DVP-SV MPU sends out explicit request message to DVPDNET-SL according to WPL program.
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.
6.2
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.

„ ReqID: The request ID. Whenever an explicit message is sent out, the message will be given a ReqID
for DVPDNET-SL to identify. For the next explicit message to be sent out, you have to change the ID
number. ReqID = 0 refers to DVPDNET-SL will not send out 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.

3. Notes:
„
„
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
editing area and response message editing area to 0.
„
If the slava 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.

Bit-Strobe Command

Principle of Bit-Strobe
Bit-strobe is one of the standard I/O transmission methors 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 beed
to respond with a message to the master.

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.

Display of Node Status on Network
8.1
Display of Node Status in Scan List
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 abnormality, its
corresponding bit will be On.
8.2
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. The low bytes are for error codes. For detailed
information on error codes, please refer to 9.5. Digital Indicator LED.
