8. Basic applications
The Web-IO has a wide range of different communication channels and
supports various standard protocols. We recommend that you only enable the
communication channels that are actually required for your application. This limits

Access via a web browser has the special feature that, in addition to monitoring and

With
User login

With
Administrator login

access. To do this, the option
