WISE (Web Inside, Smart Engine) is a product series developed by ICP DAS that functions as control units for use in remote logic control and monitoring in various industrial applications. WISE offers a user-friendly and intuitive web site interface that allows users to implement IF-THEN-ELSE control logic on controllers just a few clicks away; no programming is required. With its powerful and easy-to-use features, it will minimize the learning curve, shorten time to market and dramatically reduce the labor and cost spent on system development.

In response to the coming of IoT (Internet of Thing) age, a new generation Intelligent IoT Controller- WISE-5231 is developed by ICP DAS. WISE-5231 provides more supports in I/O functions; it allows connection to XV-board; supports connection to DCON I/O modules and Modbus TCP/RTU Slave modules at the same time. The wide ranges of selection options enable flexibility in I/O module integration to meet the requirements from various applications. WISE-5231 also provides Data logger function to record the I/O channel data by periodic cycle or event trigger. And it can send the data files to the control center via FTP. In addition to the CGI command sending function, WISE-5231 now supports the CGI command receiving function that allows the devices (such as IP camera) connected to the network to trigger the operation of logic rule of WISE-5231. The well-thought-out CGI command functions make WISE-5231 being able to interact with the devices flexibly in the Network environment. WISE-5231 supports various communication protocols to perform real-time I/O channel data monitoring and control. The Modbus TCP/RTU protocol of WISE allows sharing I/O channel data with the SCADA system. WISE-5231 also supports the SNMP and MQTT protocol for easy integration with the MIS, MES (Manufacturing Execution System), Facility Management, IT, Network Management systems.

WISE-5231 provides powerful and flexible integration with the I/O modules at the field side and can seamlessly integrate with the SCADA/MIS/MES/IT/Network Management systems. It also features reliable real-time I/O logic control and data logger operations. All of these features make WISE-5231 the most cost-effective I/O controller in the IoT (Internet of Thing) environment.

WISE-5231: A perfect concentrator of sensor and I/O modules in the IoT age

Industry 4.0 is based on IoT (Internet of Thing) that incorporates the technological concept of communicating and exchanging information between all facilities which brought manufacturing industry to a new era. The WISE-5231 Intelligent IoT Controller developed by ICP DAS is a perfect start point to facilitate the vision of the Smart Factory.

WISE-5231 provides powerful and flexible integration with the I/O modules and sensors at the field side, and also supports various IoT protocols for seamless integration with the SCADA/MIS/MES/IT/Network Management systems to transfer the real-time I/O information from the front-end modules (or sensors) to the back-end management systems. It also features reliable real-time I/O logic control and data logger operations. All of these features make WISE-5231 a perfect concentrator of sensor and I/O modules in the IoT age.
