Abstract

As part of the control system upgrade at the Advanced Light Source (ALS) the existing intelligent local controller (ILC) modules are being replaced. These modules provide real-time updates of control setpoints and monitored values. This paper describes the architecture and performance of the `ILC Replacement Modules´ which have been developed to take on the duties of the existing modules. The new modules use a 100BaseT network connection to communicate with the ALS Experimental Physics and Industrial Control System (EPICS) and are based on a commercial FPGA evaluation board running a microcontroller-like application. This paper presents results of timing and throughput tests of a prototype module as well as a detailed description of the hardware and software design.
