Advanced Frontend Control System for BESSY: Integration and Data Management Solutions

DESCRIPTION

The frontend control system at BESSY, developed by Berliner Elektronenspeicherring-Gesellschaft, integrates advanced hardware and software solutions to manage the storage ring efficiently. Utilizing industrial PLCs connected via Ethernet, the system supports multiple frontends and offers OPC server capabilities for real-time data exchange. Key features include graphical user interface support, data archiving, and configuration management, ensuring seamless interaction between devices and applications. The system is designed for scalability, with a focus on stability and user-friendliness.

  1. frontend control at BESSY storage ring frontend control system blc-server, mono-IOC 16 segments with up to 4 frontends archiving, DM2K, StripTool CTL, beamshutter state intention: • integration to global environment of BESSY • use of standard software tools • graphical user interface support • data exchange with other apps • saving of frontend configuration data Berliner Elektronenspeicherring-Gesellschaft für Synchrotronstrahlung m.b.H., Albert-Einstein-Straße 15, 12489 Berlin R. Fleischhauer

  2. frontend control at BESSY hardware: • industrial PLC‘s with ethernet connection and serial field-bus • one PLC per frontend system (present: 36, future: up to 60 ) software • support for Intel platforms and WinNT/2000 • support for OPC (OLE/COM for Process Control, standard methods for exchanging realtime automation data) • OPC server software by manufacturer of PLC‘s • problem: no device support to ChannelAccess How connect our PLC‘s to ChannelAccess?

  3. frontend control at BESSY • OPC-client with server extension to ChannelAccess, based on ActiveX control for ChannelAccess (by K.-U. Kasemir), written in VB • OPC-server: can read/write data from/to PLC‘s (PLC drivers, IO hardware driver) • OPC-client:can read/write data from/to OPC-server(s) • CA-server: serves received data to EPICS (IOC‘s, archiver etc.) Berliner Elektronenspeicherring-Gesellschaft für Synchrotronstrahlung m.b.H., Albert-Einstein-Straße 15, 12489 Berlin R. Fleischhauer

  5. frontend control at BESSY features: • small, stable and easy-to-use OPC/CA-data gateway • supports multiple OPC-servers running local or remote • graphical item-browsing • simple data modification (inspect, write) • save and restore configuration to/from disk (ASCII) • number of served items limited only by hardware restrictions/problems • no security access control available • handling of state information is difficult • problems with alarm handler Berliner Elektronenspeicherring-Gesellschaft für Synchrotronstrahlung m.b.H., Albert-Einstein-Straße 15, 12489 Berlin R.
