IP WatchDog2 Industrial

In a user-defined period, the IP WatchDog2 Industrial detects the status of internet connection, LAN connected devices and RS-232 connected devices. The IP WatchDog2 Industrial can monitor up to ten channels including up to two RS-232 and can reset one or two physical devices (two output channels).

In case the internet connection fails or any monitored device stops responding the IP WatchDog2 Industrial can restart two connected devices via its 230V/16A NO/NC relay DO.

A restart of each output channel can be realized also manually from the main page (under password).

A built-in web server is used for configuring.

5 methods of device failure detection:

  • Ping Out: IP WatchDog2 periodically sends PING requests
  • Ping In: IP WatchDog2 waits for a PING from the monitored device
  • Web client: IP WatchDog2 monitors the accessibility of a web page
  • Web server: IP WatchDog2 waits for a request for its internal WEB page
  • RS-232: IP WatchDog2 waits for a specified character sequence in RS-232 data line
