DeviceNet Network Scanner DVPDNET-SL
DVP-PLC Operation Manual 3
1 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.
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.
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. When connected to DVP-SV/DVP-EH2-L MPU, registers after
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:
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.
