Monitor digital signals and send alarm messages via e-mail

Building services engineering, automation technology and other systems typically use digital outputs to indicate faults and operating conditions. In many cases, corresponding sensors provide potential-free contacts or voltage / current carrying outputs. Indicator lamps or other signaling devices are connected to these outputs.

Fault reporting devices such as these rely on being noticed by the responsible employees.

The Web-IO Digital allows these signals to be automatically captured. Freely configurable alarms are used to determine who is informed of which signals and should receive a corresponding e-mail. This ensures that fault reporting signals are noticed even if they are only present for a short time.

The following example shows the steps needed for example to monitor the level of a tank via e-mail.

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 the Web-IO Digital 2xInput, 2xOutput at no charge for 30 days. Simply fill out a sample ordering form, and we will ship the Web-IO for testing on an open invoice. If you return the unit within 30 days, we will simply mark the invoice as paid. To sample orders

Preparations

• with power,
• configured the inputs and outputs,
• connected it to your network,
• assigned it an IP address - which with WuTility is no problem.

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

All the basic settings necessary for sending e-mail can be made from the browser on a clearly structured configuration page. Of course the Web-IO also supports modern authentication techniques such as ESMTP and SMTP after POP3.

Depending on the Web-IO model you can define up to 12 alarms which trigger sending of an e-mail. Triggers for the alarm can include the status of the inputs/outputs or a fixed time period.

The receiver and structure of the e-mail are configurable. An alarm mail can also be sent to multiple recipients.

Then the settings are saved in the Web-IO.

The Web-IO is then configured for sending e-mail.

Regardless of whether a signal comes from a limit switch, level sensor, smoke detector, Hall sensor, infrared motion detector, solenoid, vibration switch or a photoelectric sensor or induction loop - the Web-IO makes it simple to equip even existing systems with the function, and to send an e-mail if needed. Even older PLC-based systems can be retrofitted easily.
