What is Modbus?
Modbus is a serial communication protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). In simple terms, it is used to transmit data between electronic devices. It is commonly used in industrial automation systems to connect a supervisory computer with a remote terminal unit (RTU).

Modbus Complementary Technologies
OPC
OPC (OLE for Process Control) provides a standard interface for accessing data from various industrial devices, including Modbus devices. It serves as a layer on top of protocols like Modbus to provide interoperability.
OPC UA
OPC UA is a platform-independent standard for data exchange in industrial automation. It can be used alongside Modbus to provide a more modern and secure interface.
MQTT
MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol often used for IoT applications. It can be used to transport data from Modbus devices to cloud platforms or other systems, making it complementary.
