The web based interface allows the TCW181B to be configured, controlled and monitored via web browser.

Monitoring

After successful authorization, the Monitoring page appears:

The Monitoring page provides information about the state of the digital input and relay output of the controller. To change the state of the relays , the “ON/OFF” buttons should be pressed. If the Pulse button is pressed the relay will change its state for the time specified in the “Pulse Duration” field in the “I/O Setup ” page. Three buttons are located on the bottom of the page:

All ON – clicking this button will turn all relays ON
All OFF – clicking this button will turn all relays OFF
Pulse All – clicking this button will change the states of all relay outputs fir the time specified in the “Pulse Duration” field in the “I/O Setup ” page.

I/O setup page

The following parameters can be set for the relays:

Description – brief description of the output, maximum 10 characters should be used.
Pulse Duration – time for which the relay changes its state, by pushing the "Pulse" button on "Monitoring" page. This setting applies to all 8 relays

Control and monitoring using SNMP

TCW181B can be configured and monitored through SNMP (Simple Network Management Protocol). This could be done using every SNMPv.1 compatible program.

email

The TCW181B can be set to send e-mail alerts if an event occurs on the digital input. The lowing fields should be filled:

Mail to – recipient e-mail address
