Application for Web-IO Digital / Web & E-Mail:

Send switching signals by e-mail

Faults or operating states in automation, building technology or other technical equipment are often indicated by means of digital outputs. Corresponding sensors often provide potential-free contacts or voltage carrying or current driving outputs for connecting signal lamps or other signal generators.

These are just the sort of signal sources that the Web-IO Digital can communicate with.

Report limit violations

When there is a signal change or at a specified interval the Web-IO can send emails.

The existing network is used as the communication channel. An email message can also be sent to multiple recipients.

This lets you ensure that fault reporting signals such as are generated when limits are exceeded for example are also noticed by responsible personnel even if they are present for only a short time.

Existing systems can incorporate the Web-IO Digital to achieve this email function. Even older PLC setups can be easily retrofitted.


Configuring Web-IOs for sending emails

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
  • First check whether all the IP parameters are correctly configured. Especially when using public mailservers it is important that both the gateway and the DNS server are entered. To do this, in the menu tree select Basic settings >> Network and there Basic network settings.

    Web-IO email

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

  • To configure the mail server, select in the menu tree Communication channels >> Mail.

    Web-IO email

  • Enter the access data for your email account.
    Tip: Some email providers do not allow as sender name the email address belonging to the email account. Other providers require that the reply address be the email address belonging to the email account.

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

    Web-IO Box-to-Box
  • Assign a meaningful name for your action and select the trigger for sending email.

  • As the action select Email message and configure recipient, subject and mail text (if needed also for the Clear message).

  • Multiple email recipients can be entered one after the other separated by semicolons.

  • When needed you can enable cyclical repetition of the email. As long as the trigger condition exists the email is re-sent at the specified interval.

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.
