Application for Web-IO Thermometers / Web-IO Digital:

Switching digital outputs when limits are exceeded

Turn on an indicator lamp when a limit is exceeded by 25°C. If the temperature is back to the valid range, turn the indicator off again.

  • W&T easy start

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

  • No additional settings on the Web-IO Digital are necessary.

    Define a TCP client alarm in the Web-Thermometer.

    Enter your alarm limits as usual and configure the TCP client alarm by specifying as the TCP text the HTTP instruction for turning Output 1 of the device ’webiodigital.intranet.de’ on and off.

  • This configuration ensures that when the temperature alarm of the Web-Thermometer is tripped, Output 1 of the Web-IO Digital turns on and then off when the alarm for Output 1 is deactivated.
