Modbus TCP Remote I/O Communication Module RTU-EN01

1 Introduction

To ensure correct installation and operation of RTU-EN01, please read this manual carefully before using your RTU-EN01. RTU-EN01is an Ethernet remote I/O module for remote setting through Delta’s DCISoft. RTU-EN01 supports maximum 256 digital input/output points. RTU-EN01 supports Modbus TCP protocol and can be used for remote monitoring with graphic control software or human machine interface. RTU-EN01 can also be used as a Modbus TCP gateway, supporting the conversion from Modbus TCP commands to Modbus ASCII/RTU. In addition, in MDI/MDI-X auto-detect, jump wire is not needed when you choose the network cable.

1.1Features

z Supporting smart PLC functions, counter, timer and real-time clock. Able to operate independently without control of PLC main processing unit or programming.

z Able to auto-detect 10/100 Mbps transmission speed; MDI/MDI-X auto-detect.

z Supporting maximum 16 digital input/output modules (Max. 256 I/O points) and 8 analog input/output modules.

z Supporting maximum 16 sets of Modbus TCP connections.

z Supporting Modbus TCP/Modbus gateway (supporting Master mode, connectable to maximum 32 devices). z Parameters can be set up on webpage.
