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 ѕ 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. ѕ 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. DVP-PLC Operation Manual 1
