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.

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.
