Web-IO - System integration
Automation with standard protocols
Integrating signals with Modbus-TCP, OPC UA/DA, REST or MQTT
Automation technology in industry most often involves hardware components from many different manufacturers combined in a common system. It used to be that the data exchange needed for such systems was handled by many different fieldbus systems.
Even before the advent of Industry 4.0 there has been increasing use of standardized TCP/IP-Ethernet based network protocols.
Seamless integration into modern automation technology is supported by the W&T Web-IO 4.0 products using the following industrial protocols:
- OPC UA
- OPC DA
- Modbus-TCP
- REST
- MQTT
This makes the Web-IO 4.0 products ideal for use in industrial applications.
Even older machines that have to use switching outputs or analog signals to indicate their operating states can be incorporated into modern systems by using the appropriate Web-IO.
The result is a bridge between traditional automation technology and up-to-date network communication as current as Industry 4.0 and IoT.
