The iNELS Bus system utilizes a 2 wired bus network infrastructure to connect and control different components and devices throughout the building. It employs a decentralized architecture, where each subsystem on the bus has its own intelligence and can communicate with others directly. The iNELS Bus protocol uses a combination of wired connections, such as RS-485, Dali, Modbus, and wireless technologies like RF (radio frequency) to establish communication links. iNELS bus also uses network protocols such as IP and MQTT to communicate with 3rd party world. This allows for flexibility in the system design, supporting both new installations and retrofitting into existing buildings. {% embed url="" %} {% embed url="" %} {% embed url="" %} --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://wiki.inels.com/inels-bus/introduction/what-is-inels-bus.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
