Modbus. Controlling the Charger Like Air Conditioning.

Back to blog
Modbus is a widely-used communication protocol in industrial automation systems.

It was developed by Modicon in 1979 and is now owned by the Modbus Organization, which is responsible for the maintenance and development of the protocol. Modbus is an open protocol, meaning that it can be used by anyone without the need for any license or fees.

Modbus is a serial communication protocol that is used to communicate between devices in a supervisory control and data acquisition (SCADA) system. The protocol is simple and easy to implement, which has contributed to its popularity in industrial applications. Modbus can be used to connect a wide range of devices, including programmable logic controllers (PLCs), human-machine interfaces (HMIs), remote terminal units (RTUs), and sensors.

Modbus is based on a client-server architecture, where the client is typically a master device and the server is a slave device. The master device initiates the communication by sending a request to the slave device, which responds with a message containing the requested data. The communication can be either read or write operations.

One of the key advantages of Modbus is its flexibility. The protocol can be used with a wide range of communication media, including serial, Ethernet, and wireless. This means that Modbus can be used in a variety of applications, from small local networks to large distributed systems.

Another advantage of Modbus is its scalability. The protocol can be easily adapted to different system sizes and configurations, making it ideal for use in industrial automation systems.

The implementation of the Modbus protocol in the Enelion Lumina station allows you to connect our charger to another superior remote management system – such as a home assistant or BMS (Building Management System).

Thanks to this, you can communicate and control stations such as, for example, the air conditioning system in a building to, for instance, optimize energy consumption.
