The general purpose data acquisition system MBS

The GSI data acquisition system MBS (Multi Branch System) has become, since its introduction in 1994, the standard system at GSI (37 active systems+9 portable systems). It is also used at numerous outside laboratories (29 systems active). The current version MBS 2.2 will be replaced by the version 3.0, which contains three major enhancements. First, the data busses are no longer restricted to address mapped devices. It allows now also the usage of message oriented busses, like Ethernet (100 Mbit, Gigabit) or ATM. Second, a data acquisition system can now be configured with multiple event builders to increase the overall data rate on output devices. Third, a graphical user interface, written in Java has been implemented.
