Are there any examples of SCADA with an Arduino client over the Internet?

Question

Arduino

Good afternoon everyone!
Interested in such a task as collecting data into one SCADA system from several remote Arduino boards located in the GSM coverage area. Has anyone tried to solve the problem of exchanging data between an Arduino with a GSM module and OPC servers over the Internet? Are there any standard solutions (for example, based on Modbus TCP or similar), or is additional software required? All the topics discussed involve the direct connection of the Arduino to a computer with a SCADA system, and the task is precisely in remote connection / interrogation / transmission of data and control signals

Answer 2

You can transfer via MQTT, write your own OPC server in python, which works with MQTT.

Answer 3

The simplest thing that can be implemented on the Arduino side is modbus. You just need to decide whether it will be modbus RTU or modbus RTU. If the poll is supposed to be from the server side, then implement it in the arduino slave. and on the server side, to put scada that can work with modbus on its own, or to find a modbus opc server - this, I think, is not a problem.
