	European Spallation Source (ESS) will be constructed by a number of partner institutions in an international collaboration, thus increasing organizational risk as control system integration will be performed by a large number of independent teams. From the earliest stages in the project a lot of effort will be put into standardization of hardware, software and development procedures. ESS will use EPICS control system and will build on the positive experience of SNS and ITER. The basic unit of standardization is called the Control Box, and consists of one or more input/output controller (IOC) computers, zero or more I/O modules, PLC subsystems and intelligent special-purpose controllers, with all the software and a fully integrated development environment support. In this article we present the challenges faced by the Control Box concept and the benefits it brings.

	We discuss control systems of accelerators and similar projects that are presently still in design and early construction phases, such as FAIR, ESS, MedAustron, NSLS II, ITER, etc, and comparing them against the approaches of the last two decades and explain the new trends that are emerging: · From the organizational perspective, control system architectures are established earlier in the project, allowing them to adapt to the machine physics requirements better as well as allow for modeling and simulations. · In software, there is much less emphasis on custom codes than there was in the past. Instead, standard and off-the-shelf components and frameworks already used at existing accelerators are becoming the preferred choice, not only reducing risks, but also allowing for reuse and sharing. · In hardware and networks for real-time control and data acquisition, there is a strong trend from custom electronics development to standard and off-the-shelf solutions. This in particular applies to systems like timing, machine protection, BPMs and LL RF. When custom solutions are needed, flexible hardware technologies (e.g., FPGA) are chosen to allow for future extensibility.

FRCOAA01	ITER control system development environment	204

	ITER is a large tokamak fusion facility whose construction is organized in such a way that the plant systems it consists of will be delivered in-kind by the seven participating countries. Integration of the plant systems is thus expected to be particularly challenging. To make integration of instrumentation and controls of plant systems as smooth as possible, the ITER Control, Data Access and Communication (CODAC) team prepared a Plant Control Design Handbook, which specifies in detail the interfaces between the plant systems and the central system. To facilitate compliance with the handbook, a development environment has been prepared for plant system controls developers, which standardizes the operating system, control system infrastructure, development tools and development processes. In this paper, we describe the ITER CODAC development environment: what open-source software was selected, how it is packaged for ITER CODAC, what infrastructure for development is in place, what challenges were encountered and what the roadmap is for the foreseeable future.
