  The special properties of the neutrons allow to study the matter structure and dynamics of atoms and molecules. Neutron scattering is applied in a wide range of research fields such as chemistry of materials, biology, magnetism and pharmacy. The European Spallation Source ERIC (ESS) will be the most powerful neutron source in the world with the vision to help the researchers to develop new solutions for the challenges of our time. Inside the Integrated Control System Division (ICS), the Protection Systems group will provide a Beam Interlock System to protect the beam and to avoid the activation of equipment. One of these interlock systems is the Machine Protection System for Magnets (MPSMag), which collects the signals coming from each of the 150 quadrupoles distributed along the 600 meters long LINAC to prevent beam losses. The MPSMag first prototype has been implemented using industrial Programmable Logic Controllers (PLCs), the Profinet real-time fieldbus communications protocol, and Siemens TIA Portal software to fulfill the high availability requirements of the facility. The concept of operation, the state machine, and the electrical design will be presented.
