The Accelerator Control System at Fermilab has evolved to enable this relatively large control system to be encapsulated into a "box" such as a laptop. The goal was to provide a platform isolated from the "online" control system. This platform can be used internally for making major upgrades and modifications without impacting operations. It also provides a standalone environment for research and development including a turnkey control system for collaborators. Over time, the code base running on Scientific Linux has enabled all the salient features of the Fermilab's control system to be captured in an off-the-shelf laptop. The anticipated additional benefits of packaging the system include improved maintenance, reliability, documentation, and future enhancements.

Fermilab's homegrown fire and security system (known as FIRUS) is highly reliable and has been used nearly thirty years. The system has gone through some minor upgrades, however, none of those changes made significant, visible changes. In this paper, we present a major overhaul to the system that is halfway complete. We discuss the use of Apple's OS X for the new GUI, upgrading the servers to use the Erlang programming language and allowing limited access for iOS and Android-based mobile devices.

At ICALEPCS '09, we introduced a source code generator that allows processes to communicate safely using native data types. In this paper, we discuss further development that has occurred since the conference in Kobe, Japan, including adding three more client languages, an optimization in network packet size and the addition of a new protocol data type.

We have developed a new front-end framework for the ACNET control system in Erlang. Erlang is a functional programming language developed for real-time telecommunications applications. The primary task of the front-end software is to connect the control system with drivers collecting data from individual field bus devices. Erlang's concurrency and message passing support have proven well-suited for managing large numbers of independent ACNET client requests for front-end data. Other Erlang features which make it particularly well-suited for a front-end framework include fault-tolerance with process monitoring and restarting, real-time response,and the ability to change code in running systems. Erlang's interactive shell and dynamic typing make writing and running unit tests an easy part of the development process. Erlang includes mechanisms for distributing applications which we will use for deploying our framework to multiple front-ends, along with a configured set of device drivers. We've developed Erlang code to use Fermilab's TCLK event distribution clock and Erlang's interface to C/C++ allows hardware-specific driver access.
