Giới thiệu về OPC UA I/O module

OPC UA I/O module is a series of IIoT Ethernet I/O modules, known as UA I/O or U-7500 Series. It has a built-in dual-port Ethernet switch to implement daisy-chain topology. The cabling is much easy and can reduce the total cable and switch cost. It follows IEEE 802.3af (Class 2) compliant Power over Ethernet (PoE) specification. It allows receiving power from PoE enabled network by Ethernet pairs. This feature provides greater flexibility and efficiency to simplify system design, save space, and reduce wirings and power sockets.

In industrial communication, UA I/O supports the OPC UA server and MQTT client and RESTful API communication functions (and can be used simultaneously). Users can choose the networking mode according to their needs and environment, to transmit the values of built-in I/O channels to the Cloud system or field control system for displaying, analysis or strategy. Support Scaling. Let the analog signal be converted into a more readable value. Support logic function rule setting IF, THEN, ELSE, can set up logical condition/action for I/O and virtual point; Provide schedule function to execute the set rules at a specific time; and support RESTful API function, can read/write I/O and virtual point through HTTP or HTTPS(identity verification and communication encryption).

In the information security and data security of the platform connection method, the following functions are provided respectively to enhance the security of I/O networking:

 UA I/O Series provides a Web-based User Interface (Web UI) to configure the module, control the output channels, monitor the connection, and I/O status via a normal web browser. It is easy, fast, and no extra APP needed.

UA I/O Module Motor Monitoring Applications

[Customer Needs]

1. Monitoring the motor special-output current in the factory
2. High security data transmission
3. Monitor the factory through wireless according to the client's needs

1. Designed to monitor the special-output current motor in the factory

The input of the electric meter is 50 / 60 Hz, and the output of the motor in the field is 50 / 6000 Hz, the precision is not enough to use an electric meter for motor monitoring, therefore, a high-frequency CT is used to monitor the motor output current.

2. Enhanced data transmission with high security

The U-7500 series modules transfer the motor= streaming data through OPC UA and MQTT protocols with high security, so the information security of the factory can be improved.

3. Monitoring the client's factory via wireless

Through the RJ45 to Wi-Fi adapter, the wired signal in the factory is converted to wireless signal transmission, allowing customers to monitor the factory.

Environmental Monitoring and Maintenance Applications

Using ICP DAS IoTstar with UA I/O solution can bring many benefits. In this case, the customer uses IoTstar cloud management software combined with UA I/O module series to set up a cloud IoT monitoring system, and the manager can get the following benefits.
** Support IoTstar cloud management software 

1. No programming is required

Collect environmental parameters and store them in the cloud database, the system can be set up through the web interface without writing programs.

2. Collection and monitoring of production line information

Check environment parameters of the site in real-time via IoTstar Dashboard Service, information on the production line can be collected and monitored completely.

3. Reduce the cost of equipment maintenance

Through IoTstar Remote Access Service, cloud monitoring, setting adjustment, and firmware updates can be performed, reducing the time and cost of personnel movement due to equipment maintenance.

Smart Lighting Control System for Biomedical Factory

Various smart devices have been added to daily life. Smart lighting control can achieve energy savings, data analysis, and remind maintenance of lighting equipment. However, it also faces the threat of security attacks. ICP DAS has installed an intelligent lighting control system to provide stable lighting and arrange maintenance to reduce management costs.

The new function reduces the distance between the new technology and people by retaining the traditional light control panel switch. It provides the service when the lighting control moduleneeds to be repaired. The security of data transmission using the network interface for lighting control also needs to be considered.

System Architecture

ICP DAS on the lighting control system for medical factorys, in addition to the traditional lighting and physical switches, six additional units have been added, a lighting control panel, network switch, touch screen, communication server, factory monitoring system, and monitoring and early warning system.
 

The lighting control can also be integrated with various sensors to realize context-based dimming functions to achieve energy-saving effects, and data analysis can be added to remind equipment maintenance to reduce management costs.

1. Lighting Control Panel

The control core is the U-7555M module. The digital outputs and inputs on the module are wired to the relays of the lighting circuits and the lighting panel switch, respectively. This module also provides logic and scheduling control. It's a stand-alone lighting control module. Provides three highly secure data exchange protocols, OPC UA, MQTT, and Restful API (https) to reduce information security risks.

2. Network Switch

The network switch is daisy-chained to the U-7555M in the lighting control panel, the user expects to install the touch screen on the cubicle wall and integrated it into the main network. The communication protocols are not polling mechanisms, the bandwidth requirements for the factory are extremely low.

3. Touch Screen

The touch screen is available in 2.8", 4.3", or 7". Small size fi ts only light switches, large size with other settings that can be integrated, such as air conditioning, access control, power information, environmental sensor information,etc. It can also use a control interface for lighting and air conditioning.

4. Communication Server

BRK-2841M provides the Broker function of MQTT protocol for MQTT message dispatching and proxy. It is compliant with MQTT V.3.1, 3.1.1, and 5.0 protocols, and supports the QoS message quality mechanism, retention mechanism, identity verifi cation, communication encryption, Last Will, and bridging function. Supports Web UI setting to quickly set up the BRK function, which can reduce the burden of setting up the Broker by individuals and reduce management costs. Itprovides clustering, bridging, load balancing, and high availability functions to prevent service downtime due to system failure in the field.

5. Factory Monitoring System

Using AVEVA Edge to integrate water, electricity, gas, lighting, access control, etc. within the factory. Provides the information in real-time on factory computers, handheld devices, and databases where information is not immediately available but needs to be stored. The former provides a stable production environment, while the latter is used for data analysis and supplied maintenance notification, etc.

6. Monitoring and Early Warning System

The network planning is based on the Purdue model of IoT, but most of the equipment purchased in the factory cannot provide high-security communication protocols. Therefore, a monitoring and early warning system is built to monitor IP and devices without encrypted communication protocol (Modbus TCP) in the factory in real-time, and notify MIS, factory management and record notification in case of abnormalities.

Plastic Injection Molding Machine Monitoring Applications

Due to labor costs increasing and manpower shortages in the manufacturing industry, how to digitize information is an important issue, companies have trouble integrating IT and OT staff because they have different perceptions, and eventually have to abandon the project. The difficulties, in this case, can be divided into the following items:

1. Hard to record Sensor value
2. Machine messages scattered
3. No Data Graphing 

ICP DAS uses the U-7526M to convert analog signals into RESTful API / MQTT data to achieve the goal of "information digitization". Makes it more flexible for database and graphic software and makes it easier to control and record. 

Advantages of ICP DAS:

1. Digitalization for recording
2. Centralized message
3. Data graphing
