IP-Watcher 2x2 Digital I/O
The IP-Watcher generates an alarm when network components no longer respond.
Devices are watched by cyclically pinging or regular opening and closing of a selectable TCP port. In case of a fault, switch on an alarm or report via the network, e.g. e-mail or SNMP trap. In addition, the IP-Watcher offers an SNTP service which can be used to obtain the current time information for any network clients.

Example applications
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.
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.
