	The European Spallation Source (ESS) project is starting the construction of buildings June 2014. When the access to linac tunnel and gallery building is ready, the commissioning of the first sections of the accelerator starts. A proper operation of the machine relies on the services provided by different infrastructure systems (water cooling, electrical power system, ventilation, etc.) These systems will be used long before beam operation starts and need to be operated via the Integrated Control System (ICS) from the Control Room. Due to the number and variety of these systems, their heterogeneous characteristics and the different teams of designers, the integration process into ICS is challenging. Experience in other facilities [2,3] shows that a late integration produces higher maintenance and operation costs, and even impact on the reliability of the machine. This paper presents the strategy developed by two partners, the Controls and Conventional Facilities Division (CF). It is planned to capture the requirements for the interfaces and to ensure an early integration of Infrastructure Systems into the EPICS environment. First results of this approach are shown for some systems.

THPRO118	A PLC Test Bench at ESS	3171
	D.P. Piso, M. Reščič ESS, Lund, Sweden G. Cijan Cosylab, Ljubljana, Slovenia R. Schmidt CERN, Geneva, Switzerland
	The European Spallation Source (ESS) is an accelerator- driven neutron spallation source. The Integrated Controls Systems (ICS) is responsible for providing control and mon- itoring for all parts of the machine (accelerator, target, neu- tron scattering systems and conventional facilities) [1]. A large number of applications have been identified across all parts of the facility where PLCs will be used: cryogenics, vacuum, water-cooling, power systems, safety and protec- tion systems. The Controls Division at ESS is deploying a PLC Test Bench. The motivation is to evaluate different technologies, to test PLCs and their integration into EPICS, to prototype control systems and use the test bench as PLC software development platform. This report defines the ar- chitecture of this infrastructure. The first stage to procure a first set of hardware and to perform initial tests has already been finished, consisting of a comparison between the per- formance of the s7plc EPICS driver and the Modbus EPICS driver. The results of these tests are discussed and future plans for this infrastructure are presented.

	The European Spallation Source (ESS) is one of Europe’s largest planned research infrastructures. The project is funded by a collaboration of 17 European countries and is under design and construction in Lund, Sweden. Three families of Superconducting Radio-Frequency (SRF) cavities are being prototyped, counting the spoke resonators with a geometric beta of 0.5, medium-beta elliptical cavities (β=0.67) and high beta elliptical cavities (β=0.86). The ESS linac will produce 2.86 ms long proton pulses with a repetition rate of 14 Hz (4 % duty cycle), a beam current of 62.5 mA and an average beam power of 5 MW. A control system is being developed to operate the different accelerator systems. All operating modes of the superconducting linac shall ensure a safe operation of the accelerator. This paper presents the preliminary functional analysis and the operating modes of the 704 MHz SRF linac.

The European Spallation Source (ESS) project is starting the construction of buildings June 2014. When the access to linac tunnel and gallery building is ready, the commissioning of the first sections of the accelerator starts. A proper operation of the machine relies on the services provided by different infrastructure systems (water cooling, electrical power system, ventilation, etc.) These systems will be used long before beam operation starts and need to be operated via the Integrated Control System (ICS) from the Control Room. Due to the number and variety of these systems, their heterogeneous characteristics and the different teams of designers, the integration process into ICS is challenging. Experience in other facilities [2,3] shows that a late integration produces higher maintenance and operation costs, and even impact on the reliability of the machine.

The European Spallation Source (ESS) is an accelerator- driven neutron spallation source. The Integrated Controls Systems (ICS) is responsible for providing control and mon- itoring for all parts of the machine (accelerator, target, neu- tron scattering systems and conventional facilities) [1]. A large number of applications have been identified across all parts of the facility where PLCs will be used: cryogenics, vacuum, water-cooling, power systems, safety and protec- tion systems. The Controls Division at ESS is deploying a PLC Test Bench. The motivation is to evaluate different technologies, to test PLCs and their integration into EPICS, to prototype control systems and use the test bench as PLC software development platform. This report defines the ar- chitecture of this infrastructure. The first stage to procure a first set of hardware and to perform initial tests has already been finished, consisting of a comparison between the per- formance of the s7plc EPICS driver and the Modbus EPICS driver. The results of these tests are discussed and future plans for this infrastructure are presented.

The European Spallation Source (ESS) is one of Europe’s largest planned research infrastructures. The project is funded by a collaboration of 17 European countries and is under design and construction in Lund, Sweden. Three families of Superconducting Radio-Frequency (SRF) cavities are being prototyped, counting the spoke resonators with a geometric beta of 0.5, medium-beta elliptical cavities (β=0.67) and high beta elliptical cavities (β=0.86). The ESS linac will produce 2.86 ms long proton pulses with a repetition rate of 14 Hz (4 % duty cycle), a beam current of 62.5 mA and an average beam power of 5 MW. A control system is being developed to operate the different accelerator systems. All operating modes of the superconducting linac shall ensure a safe operation of the accelerator. This paper presents the preliminary functional analysis and the operating modes of the 704 MHz SRF linac.
