Description
After 31 years of operations the Italian third generation synchrotron light source Elettra will be replaced by Elettra 2.0, a fourth-generation one. The upgrade project includes the construction of at least five new beamlines, bringing the total to 32. We are using the dark period to replace the existing beamline Personnel Safety System with the new Beamline Access Control System BACS 2.0. Based on PILZ fail-safe PLC, it controls the user access to the radiation hutches of Elettra 2.0. The access to each hutch is based on individual permissions using a personal RFID key. BACS 2.0 is modular in both hardware and software: its architecture has been designed in order to be scalable and capable of managing up to eight hutches. A TCP modbus Tango device and a dedicated web interface have been developed for monitoring the system. The new PSS has successfully been installed on four beamlines and six more installations are planned for 2026.
