Mapping different devices and systems into one data model supports reliable monitoring and sustainable operations.
Where is Modbus used?
Modbus RTU/TCP commonly reads measurements and status from equipment registers at the field layer.
The roles of IEC 104 and MQTT
IEC 60870-5-104 supports telecontrol and remote telemetry, while MQTT supports central data transport and messaging.
Questions and answers
Does every device connect directly to the cloud?
A remote agent or field communication layer can bridge equipment to central systems. Protocol, network and security design follow the project architecture.
