DeviceNet Network Scanner DVPDNET-SL

1Introduction

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.

1.1Features

z Supports Group 2 server device and Group 2 only server device.

z Supports explicit connection via predefined Master/Slave connection set. z Supports DeviceNet Master mode and Slave mode.

z Supports EDS configuration in DeviceNet configuration tools.

1.2Basic 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:

zClient function of explicit message.

zAll kinds of I/O connections established between the slave: polled, bit-strobed, change of state and cyclic.

zAs the connection interface between DeviceNetBuilder configuration software and DeviceNet network. The configuration software is able to directly configure the network through DVPDNET-SL.

zSending explicit messages for reading/writing the data in slave through PLC ladder diagrams.

zAutomatically 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.

zOffering 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:

zExplicit message serve and Group 2 only serve connection mode.

zPolling

zOffering 256 bytes for input data and 256 bytes for output data in data exchange with master.

zAutomatically exchanging data with PLC MPU. The user needs only to edit the D register in the PLC without using FROM/TO instruction.
