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 / Client 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.

Features

• Built-in OPC UA Server Service
  Compliance with IEC 62541 Standard. Provides functions of Active Transmission, Transmission Security Encryption ( SSL / TLS ), User Authentication (X.509 Certificates / Account password), Communication Error Detection and Recovery, etc. to connect SCADA or OPC UA Clients. Recommend to keep the maximum number of sessions within 3 connections.
   

  
   

• Built-in OPC UA Client Service
  Compliance with IEC 62541 Standard. Provides Transmission Security Encryption ( SSL / TLS ), User Authentication (X.509 Certificates / Account password) and OPC UA Server Connectivity.

 

• Built-in MQTT Client Service
  Build-in MQTT Client Service (Compliance with MQTT V.3.1.1 protocol). Provides functions of IoT Active M2M Transmission, QoS (Quality of Service), Retains Mechanism, Identity Authentication, Encryption, Last Will, etc.

 

 Support RESTful API Function  

• Can read/write I/O and virtual point through HTTP.
  Provide high-security HTTPS (identity verification and communication encryption) to read/write I/O and Virtual points.

 

• Support to Execute OPC UA , MQTT and RESTful API Communication at the Same Time

 

• Support IoTstar Cloud Management Software
  UA I/O factory version 9.7 and later supports this function.

 

• Support Scaling
  AI/AO modules support Scaling. Let the analog signal be converted into a more readable value.

 

• Support Logic Function Rule Setting: IF, THEN, ELSE  
  Users can set up logical condition/action for I/O and virtual point.
   

 

• Support Schedule   
  Provide schedule function to execute the set rules at a specific time.

 

• Support Event Log 
  When the I/O value changes, record the current I/O value for easy device tracking in the future.
   

 

• Built-in Web Server to Provide the Web User Interface
  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.

  
   

• Diversified Choices
  Different models provide different AI, AO, DI, or DO channels, and users can choose the desired model according to the needs of the case.
   

  
  
   

• Dual-port Ethernet Switch for Daisy-Chain Topology
  The cabling of Daisy-Chain Topology is much easier and total costs of cable and switch are significantly reduced. 
   

  
  
   

• IEEE 802.3af-compliant Power over Ethernet (PoE)
  UA I/O follows IEEE 802.3af (classification, 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.
