Switch, monitor and count ...

With the Web-IO 4.0 Digital switching signals can be controlled, acquired and monitored over TCP/IP Ethernet. Numerous web and network services are available for reporting changes on the inputs and outputs - even directly in a browser. With protocols such as OPC UA, MQTT and REST the Web-IO is an ideal fit in the world of Industry 4.0 and the Internet of Things.
