Modem Machine - Sending alarm SMS messages

Modem Machine is an application, written for SlimLine Compact Ethernet CPUs, that allows the sending of SMS alarm messages about the status change of digital inputs and the activation of digital outputs when receiving SMS messages containing configurable character strings.
The application also allows the activation of a digital output when receiving calls from a user list, through caller identification (CLI).

8 users (8 mobile numbers), 6 digital inputs, 4 digital outputs are managed.

Unlike standard market products this application, being written in IEC61131-3, on a programmable product, can be adapted on request to specific customer needs.

The application is fully configurable from web page thanks to the web server integrated in the CPU SlimLine.
