Modbus TCP Remote I/O Communication Module RTU-EN01

DVP-PLC Operation Manual 1

Introduction

3This operation manual only provides introductory information on electrical specification, installation and wiring.

3RTU-EN01 is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust, humidity,

electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key

or specific tools are required to open the enclosure) in case danger and damage on the device may occur. DO NOT

touch any terminal when the power is switched on.

3Please read this manual carefully and follow the instructions to avoid damage on the product or harm on staff.

Modbus TCP Remote I/O Communication Module RTU-EN01

DVP-PLC Operation Manual 3

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.

1.1 Features

zSupporting smart PLC functions, counter, timer and real-time clock. Able to operate independently without

control of PLC main processing unit or programming.

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

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

modules.

zSupporting maximum 16 sets of Modbus TCP connections.

zSupporting Modbus TCP/Modbus gateway (supporting Master mode, connectable to maximum 32 devices).

zParameters can be set up on webpage.
