RAC18-IP Software User Manual | iC Knowledge Base

Introduction

The RAC18-IP is a multifunctional device providing comfort in a single room or a zone in the building. 18 onboard I/O’s with Ethernet and serial port make the controller a versatile system for comfort management, light and blind control, and integration and monitoring. The RAC18-IP controller is driven by the nano EDGE ENGINE–the cutting-edge software that allows for constructing multiple applications and provides a set of libraries and components tailored to create cycle-driven user applications. The device has an automatic BACnet IP and Modbus TCP/IP exposure and allows for real-time programming. Maintenance and programming of the device are possible from anywhere in real time with a dedicated, free-of-charge tool. The RAC18-IP ensures an easy replacement process with a system and applications on a removable SD card.

Programming Tools

iC Tool

The iC Tool is a free programming tool dedicated to all devices based on the nano EDGE ENGINE software engine. The iC Tool is a portable, Windows-based software for commissioning, real-time programming, updating, and managing the supported nano EDGE ENGINE devices. The iC Tool covers all requirements to create and manage applications: it has a wire sheet for convenient visual programming, property sheets for details; it offers libraries management, real-time monitoring of system states and slots values, logs, and deployment.

nE2 Link

The nE2 Link for Niagara is a comprehensive solution designed to enhance the Niagara Framework by enabling seamless commissioning, programming, and control of nano EDGE ENGINE devices.

The module is addressed to current and future Niagara Framework users who want to comprehensively manage, program, and integrate nano EDGE ENGINE devices directly into the Niagara 4 environment.

Using the built-in functionalities in Niagara, nE2 Link extends its capabilities to include nano EDGE ENGINE functions natively. The extension greatly extends the reach and usability of nano EDGE ENGINE devices, making it easier for users to integrate and manage building systems directly into Niagara 4, without the need for third-party tools.
