Introduction

ICS Framework (IFW) version 2.0 is the second version of the framework in the pre-release phase. The framework is being developed by ESO and intended as toolkit to help instrument developers to implement their control systems. This version (2.0) includes the components according to the incremental delivery plan of the IFW.

Scope

This document is the transfer document for the ELT ICS Framework version 2. The intended audience are ELT users, consortia developers or software quality assurance engineers.

Overview

The framework components included in version 2 are:

• Application Framework (rad) version 2

• Test Framework (etr) version 2

• Sequencer (seq) version alpha

• Function Control Framework (fcf) version 2

• Online Data Processing (odp) version alpha

• Some miscellaneous core libraries (ctd and dit) version 2

With the upgrade of IFW from SVN to GIT and the adoption of GitLab, we have changed the structure of our software. We have divided the IFW is several independent WAF projects, see the picture below.

IFW GIT packages and their dependencies.

Note

The ifw-hl contains most of the IFW code and configuration files while the ifw-ll stores mainly PLC Visual Studio projects.

The links to the components release in Gitlab are :

• ifw-hl release (fcf, odp and core)

• ifw-ll release (fcf controllers)

• rad release

• etr release

• seq release

Note

Repository for Binaries:

We are still using SVN for storing binaries while we are investigating how to integrate GIT Large File Storage (LFS). This includes but not limited to PLC compiled libraries, PLC modules and other utilities (binaries for Windows).

ESO does not ensure that solutions included in version 2 are not subject to changes in future releases. The future upgrade of ICS Framework to the Core Integration Infrastructure (CII) may introduce significant modifications to the actual interfaces and services.

While every precaution has been taken in the development of the ICS Framework software and in the preparation of the documentation, ESO assumes no responsibility for errors or omissions, or for damage resulting from the use of the software or of the information contained in the documentation.
