Introduction

This document serves as a general guide for the ICS Framework (IFW) version 2024, aiming to provide an updated ELT software stack for instrument developers. The framework is intended as a toolkit to assist instrument developers in implementing their control systems. The IFW has been validated with the following ELT packages:

• ELT Development Environment version 5.1.0 (Fedora Distribution)

• CII MAL 4.2.0

• CII Services 4.3.0

Note

From version 2024 onward, IFW changed the versioning scheme from a correlative number to a version based on the year.
