	The ESS proton beam power of 125MW per pulse (5MW average) will be unprecedented and its uncontrolled release could lead to serious damage of equipment within a few microseconds only. To optimize the operational efficiency of the ESS facility allowing for very high beam availability with high reliability towards the end-users, accidents should be avoided and interruptions of beam operation have to be rare and limited to a short time. Finding the right balance between efficient protection of equipment from damage and high beam availability is the key idea on which the ESS Machine Protection Strategy is being based on. Implementing and realizing the measures needed to provide the correct level of machine protection in case of a complex facility like the ESS, requires a systematic approach, which will be discussed in this paper.

The European Spallation Source ESS AB is an accelerator-driven neutron spallation source. The Integrated Controls System (ICS) division is responsible for providing controls and monitoring for all parts of the machine (accelerator, target, neutron scattering systems and conventional facilities). Also, Accelerator Division, Target Division and other parts of the organisation will be deploying PLC Automation Systems. A large number of applications have been identified across all the facility where PLCs will be used: cryogenics, vacuum, water-cooling, fluid systems, power systems, and safety \& protection systems. This work describes the different activities put in place and proposes the strategy followed at ESS regarding PLC technologies. This strategy consists not only of the standardisation of a PLC vendor but also testing activities, generation of documentation and standardization of other aspects (for instance, regarding installation). The documentation about PLC controls integration and standardisation and the approach to insert PLCs in the different controls workflows are described. Finally, the results of different tests (PLC timing correlation) are shown.
