Applications

Chemical Factory Water Filters Applications

* Reduce the diffi culty of obtaining PLC data and save time for IT system setup
The IT system has to record the fl ow, pressure, and water quality data of the water fi lter. It’s diffi cult to read the contents of the PLC in the fi lter tray. By deploying UA-5231M, the UA-5231M can convert PLC data into OPC UA service, which can reduce the diffi culty of equipment and system integration.

Cross-country Server Room Monitoring Applications

This case is a solution for a multinational technology company. There was a computer with an OPC Server in the server room of the Taipei branch. Uses the Modbus protocol to monitor the air conditioner of PLC to the head office in Singapore to use the graphic control system to connect remotely. In the new solution, the Taipei branch's server room was upgraded to use UA-5231 instead of a PC, therefore, gaining many advantages. The owner's graphical control system supports both OPC Classic and OPC UA. Change the graphical communication to OPC UA. It’s an upgraded method with minimal changes.

* Advantages: Replaces computers, uses OPC UA to connect to OPC Classic
The UA-5231 is an embedded IIoT server with the advantages of smaller size, less heat dissipation, and long-term operation than a PC, and provides the latest version of OPC UA Server function of the industrial communication standard protocol OPC. Compared with OPC
Classic, OPC UA provides fi rewall-friendly cross-domain communication and SSL/TLS encryption communication capabilities.

Farm Automation Solution

The farm automation solution controls the on-site cooling/heating/ventilation environmental equipment, lighting equipment, feeding equipment, and pigpen equipment through UA-5231M and the connected M-7000 modules. The upper controller XP-9000 manages daily feeding and drinking equipment of every pigpen and integrates the data of the water supply, feed volume and diet to the database, and then analyzes the data and adjusts the application to plan the best breeding solution.

Factory Automatic Solution

The factory automatic solution uses the UA controller to obtain the information such as the safety status of the production line and the temperature, voltage and current status of the inverter, then transmits them to the SCADA control system for real-time factory management. Besides, the 4G wireless can help to integrate the machine status, temperature, product yield, production parameters, electricity consumption, etc. into the ERP system via the MQTT protocol for managing the production of the global factories.
