Sending and receiving messages with messenger services as demonstrated with "Telegram"
https://support.industry.siemens.com/cs/document/109763879/
Digitalization makes its effects known for most people especially through changes in communication behavior. Smartphones are constant companions and with them, the use of one or more messenger services has become an everyday activity. To complement emails or SMS, a company can now use Messenger services in service communication as well.
Problem

A SIMATIC station is to send alarm messages, warning notifications or important information about the plant status to a service worker's smartphone via a
messenger service.

In addition, the SIMATIC station is also to receive and interpret messages.

The following Figure provides an overview of the automation task.

Sending and receiving messages with Telegram Sending and receiving messages with Telegram

The following functions are implemented in the application example:
Sending of messages to a service technician via "Telegram Messenger"
Receipt of a confirmation message from the service technician
The SIMATIC S7-1500 CPU communicates over HTTPS (Hypertext Transfer Protocol Secure) with the service technician's smartphone that has the "Telegram Messenger" app installed.
The "LHTTP_Get" block from the "LHTTP" library, part of the Libraries for Communication for SIMATIC Controllers, is used to communicate with the Telegram server.

The SIMATIC S7-1500 CPU is connected to the internet with the SCALANCE MUM856-1 via the cellular radio network.
The following Figure schematically illustrates the most important components of the solution:
