1. UA-5000 IIoT Communication Server
This chapter introducts the UA-5000 and its functions, software/hardware specifications...
1.1. Introduction
The UA-5000 is a series of data acquisition controller and also an IIoT communication server by ICP
DAS (IIoT: Industrial Internet of Things). The UA-5000 built-in OPC UA Server and MQTT Client
Service support a variety of common industrial communication protocols. Its RISC-based CPU
architecture has the advantages of small size and low power consumption that lets this series can
be placed in a small space to fit variety of rooms, equipment and case environment. In the
hardware, it provides a variety of communication interfaces, such as Gigabit Ethernet, USB, RS-232
and RS-485… ports to connect diverse devices.
Applying OPC UA can integrate the I/O products of ICP DAS with the third-party devices, import
the data information to the SCADA, database or decision-making systems for the back-end
management, and satisfy the reliability, interoperability and security needs of the industrial
automation system. Using MQTT communication can bridge the system with the Internet of
Things (IoT) to meet the current trend of the smart internet.

1.2. Function Features
Web-based UI
With the Web-based User Interface, users can log in and configure the controller via a normal
web browser that only need a mobile device or computer with web browsing capabilities.
OPC UA Server: IEC 62541 Standard
The OPC UA Server certified by the OPC Foundation can assist the integration for the
local-end devices, actively upload data to the application system, and support to across the
multiple platforms.
PID Logic Operation
The PID function can dynamically combine the remote I/O devices for the PID logic control to
provide temperature control and case field solutions.
Support Modbus TCP/RTU Master
Through the controller's RS-485, RS-232 and Ethernet ports can connect to the Modbus
TCP/RTU Slave devices. Build systems with scalability and flexibility to meet the diverse
application needs and expansion at any time.
MQTT Broker Inside
Compliance with MQTT v3.1.1 protocol. Support MQTT message distribution management.
Users do not need to build Broker system when using MQTT communications.
Support MQTT Protocol
Support MQTT to allow the IoT devices communicating with the OPC UA system and the
UA-5000 conducting the data acquisition and management; and also can convert and publish
the devices' data under the UA-5000 to the IoT system.

2. Quick Start
This chapter describes the process of creating a UA-5000 project, including how to connect to the
UA-5000 web-based UI via a browser, set web functions step-by-step, and complete a project.
2.1. Link to UA-5000 Web-based UI
The following steps will show you how to connect to the UA-5000 web interface.
Using the UA-5000 Utility (named “UA-5000utility.exe”) at the path of the companion CD (i.e.,
CD:/UA-5000/Utility/). Please copy this file to your PC, and then run it to connect the device.
Step 1
Run the UA-5000 Utility (file name: UA-5000utility.exe).
