Web-IO 4.0 Digital, 12xInput, 12xOutput

Web-IO 4.0 Digital, 12xInput, 12xOutput

Automation today uses the Ethernet
Web-IO Digital is made to handle and monitor processes over Ethernets


Switching, monitoring and counting ...

With the Web-IO 4.0 Digital, switching signals can be controlled, monitored and monitored via TCP / IP Ethernet. Numerous web and network services are available to report changes to the inputs or outputs - even directly in the browser. With protocols such as MQTT and REST, the Web-IO optimally fits into the world of Industry 4.0 and the Internet of Things.

Send messages - when limits are violated or timer-based - for informational purposes directly to the responsible technical as an e-mail or as a reroute via SMS.


After the device has been configured for and connected to your network, the following steps are still necessary.

Open the profile for configuring e-mail alarm messages. e-57606-35-pide-000
Enter the desired parameters. e-57606-36-pide-000
When the limit you have set is exceeded, the device sends an e-mail which can also be transmitted as an SMS message using special functions available from cellular phone service providers. e-57606-37-piww-000
