Applications for Web-IO Digital / Industry & data protocols

Potential-free contact triggers SNMP trap

Report limit violations

SNMP has established itself especially in medium size and large networks for monitoring and managing the network infrastructure. There are however many components such as HVAC equipment, USPs and leak sensors that are not otherwise compatible with inclusion in SNMP management systems.

The Web-IO Digital lets you bring such devices and equipment into the SNMP management system when all they provide is potential-free contacts for indicating faults and operating states.

When there is a signal change the Web-IO can send an SNMP trap to the management system. In addition the inputs and outputs are represented by the corresponding OIDs. The connected components can also be generally represented in the system.

SNMP also allows switching the outputs, for example to use a warning light for indicating faults.


Configure Web-IOs for sending SNMP traps

For the browser to have access, the Web-IO must already have an IP address.

  • To change the configuration of the Web-IO you first need to obtain the necessary access rights by entering the administrator password.

    Box to Box Master
  • Finally, check whether all the IP parameters are correctly set. In the menu tree select Basic settings >> Network and there Basic network settings.

    Web-IO email

  • In the menu tree click on Actions and then on the Add button.

    Web-IO SNMP trap
  • Assign a meaningful name for your action and select the trigger for sending the trap.

  • As the action select SNMP trap and configure SNMP Server Address, SNMP Server Port and Trap Text (if needed also for the Clear message).

  • If needed, cyclical repetition of the trap sending can be enabled. As long as the trigger condition exists, the SNMP trap is re-sent at the specified interval.

  • All the configuration changes must be confirmed using the Apply button.

As soon as these steps are completed, the outputs on the one Web-IO follow the inputs on the other 1:1. This works in both directions of course.

You don’t have a Web-IO yet but would like to try the example out sometime?

No problem: We will be glad to send you a unit at no charge for 30 days. Simply fill out the sample order form and we will ship the Web-IO on open invoice for testing. If you return the device within 30 days, we will cancel the invoice.
