A Web 2.0 approach to DAQ monitoring and controlling

In the scope of experimental set-ups for the upcoming FAIR experiments, a FPGA-based general purpose trigger and read-out board (TRB3) has been developed which is already in use in several detector set-ups (e.g. HADES, CBM-MVD, PANDA). For on- and off-board communication between the DAQ's subsystems, TrbNet, a specialised high-speed, low-latency network protocol developed for the DAQ system of the HADES detector, is used. Communication with any computer infrastructure is provided by Gigabit Ethernet. Monitoring and configuration of all DAQ systems and front-end electronics is consistently managed by the powerful slow-control features of TrbNet and supported by a flexible and mature software tool-chain, designed to meet the diverse requirements during development, setup phase and experiment. Most building blocks offer a graphical-user-interface (GUI) implemented using omnipresent web 2.0 technologies, which enable rapid prototyping, network transparent access and impose minimal software dependencies on the client's machine. This contribution will present the GUI-related features and infrastructure highlighting the multiple interfaces from the DAQ's slow-control to the client's web-browser.
