IP-Watcher 2x2 Digital

  • IP-Watcher 2x2 Digital easy start

The IP-Watcher generates an alarm when network components no longer respond.

Devices are watched by means of cyclical pinging or regular opening and closing of a TCP port. When a fault occurs, switch an alarm output or report the event over the network, e.g. via email or SNMP trap. In addition, the IP Watcher provides an SNTP service through which any network station can obtain the current time information.

Properties

One box for any application:

  • Small System
    Using the integrated Web server the IP-Watcher can be configured directly through the browser. It is also possible to monitor the configured alarms and acknowledge pending messages using the Web interface. Additional functions, such as sending email messages, enables implementation of autonomous applications out-of-the-box.
  • Big System
    Standard protocols and interfaces such as OPC, SNMP and SYSLOG enable trouble-free integration into existing systems (e.g. monitoring via SNMP with Nagios). The digital outputs can be used to report faults even on already present automation devices having digital inputs.

Alarm status

Monitor the status of the configured alarms directly from the browser.
Alarm acknowledgments can be performed directly on the Web interface by mouse-click.
The display is self-refreshing and therefore always current.

In-/output status

Additional overview of the status of the in- and outputs,
as well as of the set alarms.
