Module I/O OPC UA 8 kênh DI+8 kênh DO+2 cổng Ethernet Switch ICP DAS U-7555M CR

U-7555M is an OPC UA I/O module that provides 8 digital input channels and 8 digital output channels. It has a built-in two-port Ethernet switch to implement daisy-chain topology. The cabling is much easy and can reduce the total cable and switch cost.

U-7555M follows IEEE 802.3af compliant Power over Ethernet (PoE) specifi cation. It allows receiving power from PoE enabled network by Ethernet pairs. This feature provides greater fl exibility and effi ciency to simplify system design, save space, and reduce wirings and power sockets. It provides a Web UI to confi gure/control/monitor the modules, connections, and I/O status via a web browser. It is easy, fast, and no extra APP needed.

In industrial communication, UA I/O provides OPC UA Server and MQTT Client protocols (can execute both communications at the same time.). Users can choose the networking mode according to their cases. And to transmit the values of the built-in I/O channels to the Cloud IT system or field control system for reading and writing. Support Scaling to convert the analog signal into a more readable value.

Protocol 1. OPC UA Server
• OPC Unified Architecture: 1.02
• Core Server Facet
• Data Access Server Facet
• Method Server Facet
• UA-TCP UA-SC UA Binary
• User Authentication: Anonymous, Username/Password, X.509 Certificate
• Security Policy: None, Basic128Rsa15 (Sign, Sign & Encrypt), Basic256 (Sign, Sign & Encrypt)
• Recommend to keep the max. number of sessions within 3 connections.
• Can Execute with MQTT Communication Simultaneously2. MQTT Client
• Connect to the MQTT Broker to read or control the I/O channel value by the publish/subscribe messaging mechanism. (MQTT Ver. 3.1.1; TLS Ver. 1.2)
• Can Execute with OPC UA Communication Simultaneously
Function 1. Web Interface for Configuration
• The system operation can be performed through the browser without installing software tools.
• Use AES 256 encryption algorithm to encrypt web page setting data for general communication.2. Security
• Based on security, only the needed service ports are open up, and the rest are not open.
• Forbidden to use ping: turn off this function so that others cannot scan the device, to reduce the network attacks.
