	For the upcoming 'Facility for Antiproton and Ion Research' (FAIR) at GSI, the Front End Software Architecture (FESA) framework built by CERN has been chosen to serve as front-end level of the future FAIR control system. All future beam diagnostic devices will be controlled by FESA classes that are addressable by the new control system. The connectivity to the old control system is retained, since both control systems will be in operation contemporaneously for several years. Commercially available Programmable Logic Controllers (PLCs) have been installed as part of beam induced fluorescence (BIF) monitors to replace outdated network attached devices and to improve the reliability of the BIF systems. The new PLC devices are now controlled by FESA classes which are addressed from the existing C++ software via RDA calls. This contribution describes the system setup and the involved software components to access the PLC hardware.

WEPL010	FESA Based Data Acquisition for Beam Diagnostics at GSI	47

	In view of the upcoming Facility for Antiproton and Ion Research (FAIR) at GSI with its increased complexity in beam control and diagnostics, the decision was taken to use the well-tested CERN-made Front-End Software Architecture (FESA) as the lowest level of the new control system. In the past years, the current stable FESA framework (Version 2.10) has been adapted and installed at GSI, the major part being the adaptation of the different machine timing models of GSI and CERN. With this stable environment at hand, all current and new data acquisition systems related to beam diagnostics will be implemented with FESA. To demonstrate the applicability of FESA for demanding data acquisition problems with high data rates and/or large amounts of data, two different projects such as the Tune Orbit and POSition measurement (TOPOS) and the Large Analogue Signal Scaling Information Environment (LASSIE) are presented. Experiences with implementing standard interfaces such as CAN, GigE and PLCs in FESA applications as well as a move towards low cost Intel-based VME controllers or industry PCs running a real time Linux are discussed.
