Alto WebIO is a Modbus TCP slave and can send emails if events on the inputs.

Alto webIO is a smart remote input output module. It needn't workbench for start up.

After power on, Alto webIO seeks a IP address from a DHCP or BootP server. The operator logs on to the Alto with a browser. Alto emits the home page.

The embedded web server allows
* to configure the products (server adresses, email wording, passwords, ...)
* to display input states on line
* to force outputs for test
* to configure filtering of inputs, blinking of outputs
* to configure withdrawn output positions if ethernet communication failure
* ...
