Worth knowing

Example applications

Small System

The integrated Web server can be used to configure the Trap-Receiver directly from the browser. It is also possible to monitor the selected events and acknowledge pending messages using the Web interface. Other functions, such as reporting via email, allow out-of-the-box implementation of autonomous applications.

Big System

Standard protocols and interfaces such as OPC, SNMPv1 and SYSLOG enable trouble-free integration into existing systems. The digital output can be used to report events (faults, limit violations) to already existing automation devices having digital inputs.

Application possibilities

Receive SNMPPv1 traps and syslog messages, switch on-site, inform over the network:

The Trap-Receiver receives alarms and messages from the network via SNMPv1 and SYSLOG. 12 actions can be defined for responding to messages or alarms from the network. In addition, changes on the input terminals and even self-definable buttons can be selected as an In-Event, for example to clear an alarm, set an output or send messages. Switch an output (also with self-holding) or send a message over the network, e.g. via e-mail, TCP or SNMPv1 trap. The Trap-Receiver also offers an SNTP service which can be used to obtain the current time information for any network station.

Trap-Receiver as external software watchdog enables safety applications:

In safety-critical applications the Trap-Receiver can also be set up as an external watchdog. Send an SNMPv1 trap to the Trap-Receiver every minute for example using your PC program or network device to turn on the local output. This output remains continuously active during triggering. Only if the trap is not present for 3 minutes, for example, is the output turned off. By implementing a feedback to a device input you can also send an alarm using the above mentioned network services.

The actions and status of the terminals can be monitored directly from the browser.
Perform acknowledgements via mouse click directly in the Web interface.
2 local digital inputs available (e.g. emergency stop buttons, switches).
2 local digital outputs available (e.g. horn, indicator lamp).
Status representation is self-refreshing and therefore always up-to-date.
