Both Personnel Safety System (PSS) and Equipment Protection System are based on PLCs. The PSS is an independent system based on Pilz Safety PLCs designed to match the Safety Integrity Level 3 defined in the norm IEC 61508. The EPS uses B&R PLCs with distributed periphery located inside the Tunnel and BL Hutches. Most of the code is defined from the cable database. The cableDB is a MySQL database containing a complete information on equipments and cables and from which, besides the reports for cabling installation, most code for PLCs, device servers and expert GUIs are automatically generated. The EPS is complemented with a redundant faster protection system based on the Timing devices and transmitted over Fiber optics.

CELLS has developed a database as a main repository for the cables and control devices in the ALBA facility. Regarding cables, the database has all the information about the cable configuration (cable and connectors on both sides) and routing (trenches and cable length) as well as the devices where the cables are plugged in. The dabatase performs two checks before uploading a cable: the connector on the equipment and on the cable match, a cable was not connected yet to that equipment. The cables have different status, according to their installation process (received, installed, tested OK, tested error, etc). Regarding control devices, the database has all the information about the devices (serial numbers of computers and boards, DHCP address) and tests done (Operation system, drivers and Tango). This database has a friendly web interface for user access. It allows many types of filters for cable & devices: location in the tunnel or in the racks, by system (SR, Booster, BL1, …), by routing (name of trench).
