Warn ing



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

1 Introduction

1. To ensure correct installation and operation of DVPDNET-SL, ple ase read this chapter carefully before usin g your DVPDNET-SL.

2. This chapter only provides introductory information on DVPDNET-SL. For more detailed info rmation 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.

1.1 Features

z Supports Group 2 server device and Group 2 only server device. z Supports explicit connection via predefined Master/Slave connection set.

DeviceNet Network Scanner DVPDNET-SL

z Supports DeviceNet Master mode and Slave mode. z Supports EDS configuration in DeviceNet configuration tools.

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

cyclic.

z As the connection interface between DeviceNetBuilder configuration software and DeviceNet network.

The configuration software is able to directly configure the network through DVPDNET-SL.

z Sending explicit messages for reading/writing the data in slave through PLC ladder diagrams. z Automatically exchanging data with PLC MPU. The user needs only to edit the D register in the PLC

without using FROM/TO instruction. D6000 will be adopted temporarily.

z Offering 380-byte space for I/O input data and another 380 bytes for I/O output data.

When being used as a slave, it supports the following functions:

When connected to DVP-SV/DVP-EH2-L MPU, registers aft er

z Explicit message serve and Group 2 only serve connection mode. z Polling z Offering 256 bytes for input data and 256 bytes for output data in data exchange with master. z Automatically exchanging data with PLC MPU. The user needs only to edit the D register in the PLC

without using FROM/TO instruction.

1.3 I/O Scan List

Item Explanation Software screen

Before DVPDNET-SL starts it s 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

Scan Table

I/O Table

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.

DVPDNET-SL provides an Input Table (380

bytes) and an Output Table (380 bytes) for the data exchange with slaves. When a slav e 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 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.
