	In the framework of the LHC Injectors Upgrade Project, the new connection from Linac4, injecting a 160 MeV H⁻ beam into the Proton Synchrotron Booster (PSB) requires a set of four slow kicker magnets (KSW) per PSB ring to move the beam on a stripping foil, remove electrons and perform phase space painting. A new multiple-linear waveform generator based on a Marx topology powers each KSW, allowing adjustment of the current discharge shape with high flexibility for the different beam users. To control these complex power generators, National Instruments (NI) PXIe crates fitted with a set of modules (A/D, D/A, FPGA, PROFINET) are used. Initially, control software developed with LabVIEW has validated the test bench hardware. A full software re-engineering, accessing the hardware using Linux drivers, C APIs and the C++ framework FESA3 under Linux CentOS7 was achieved for operational deployment. This paper describes the hardware used, and the integration of NI PXIe systems into CERN controls environment, as well as the software architecture to access the hardware and provide PSB operators and kicker experts with the required control and supervision.

MOPHA152	Use of Multi-Network Fieldbus for Integration of Low-Level Intelligent Controller Within Control Architecture of Fast Pulsed System at CERN	589

	Fieldbuses and Industrial Ethernet networks are extensively used for the control of fast-pulsed magnets at CERN. With the ongoing trend to develop increasingly more complex low-level intelligent controllers near to the actuators and sensors, the flexibility to integrate these within different control architectures grows in importance. In order to reduce development efforts and keep the fieldbus choice open, a multi-network field-bus technology has been selected for the network interfacing part of the controllers. Such an approach has been successfully implemented for several projects such as the development of high voltage capacitor chargers/dischargers, the surveillance of floating solid-state switch and the monitoring of a power triggering system that, today, are interfaced either to PROFIBUS-DP or PROFINET networks. The integration of various fieldbus interfaces within the controller and the required embedded software/gateware to manage to network communication are presented. The gain in flexibility, modularity and openness obtained through this approach is also reviewed.

Fieldbuses and Industrial Ethernet networks are extensively used for the control of fast-pulsed magnets at CERN. With the ongoing trend to develop increasingly more complex low-level intelligent controllers near to the actuators and sensors, the flexibility to integrate these within different control architectures grows in importance. In order to reduce development efforts and keep the fieldbus choice open, a multi-network field-bus technology has been selected for the network interfacing part of the controllers. Such an approach has been successfully implemented for several projects such as the development of high voltage capacitor chargers/dischargers, the surveillance of floating solid-state switch and the monitoring of a power triggering system that, today, are interfaced either to PROFIBUS-DP or PROFINET networks. The integration of various fieldbus interfaces within the controller and the required embedded software/gateware to manage to network communication are presented. The gain in flexibility, modularity and openness obtained through this approach is also reviewed.
