IP WatchDog2 Industrial checks the status (OK / Failure) of an external device or system in a user-defined period using ICMP PING, a web page, or RS-232 serial data. It detects failure by sending active PING requests or waiting for a periodic Heartbeat signal.

Each output channel can also be restarted manually from the main page (password protected).

A built-in web server is used for configuration.

Device Failure Detection – 5 + 1 Methods:

• Outgoing PING: IP WatchDog2 sends PING requests periodically.
• Incoming PING: IP WatchDog2 waits for a PING from the monitored device (heartbeat).
• WWW page request (Web client): IP WatchDog2 checks if a defined web page on the external device is accessible.
• WWW page (Web server): IP WatchDog2 waits for a request from the external device for its internal web page (heartbeat).
• Requested RS-232 string: IP WatchDog2 waits for a specified character sequence on the RS-232 data line (heartbeat).
• Manual reboot: A human operator can manually reboot the channel (output).

Outputs and Channels:

• 2x Physical DO (relay) Outputs on the device / 12 Detection Channels
• 12 channels for failure detection are available in a single IP WatchDog2 Industrial device
• One IP WatchDog2 can restart or power cycle 2 physical devices (2x DO with 230V/16A NO/NC relay).
• Other channels can detect a failure state and reboot remote Virtual Outputs (external Poseidon2 or Damocles2 devices).
