DeviceNet Network Scanner DVPDNET-SL

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 Supports DeviceNet Master mode and Slave mode.

z 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 Supports client function of explicit message.

z Supports slave to establish all kinds of I/O connections: polled, bit-strobed, change of state and cyclic.

z 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.

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

z Max length for output data and input data are both 380 bytes.

¾ 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.

z Max length for output data and input data are both 255 bytes.
