WEP01	EtherCAT Driver and Tools for EPICS and Linux at PSI	EPICS, controls, real-time, PLC	22
	D. Maier-Manojlovic PSI, Villigen PSI, Switzerland
	EtherCAT bus and interface are widely used for external module and device control in accelerator environments at PSI, ranging from modulator and undulator communication and control, over motion control, basic I/O control, all the way to Machine Protection System for the new SwissFEL accelerator. A combined EPICS/Linux driver package has been developed at PSI, to allow for simple and mostly automatic setup of various EtherCAT configurations. The driver is capable of automatic scan of the existing devices and modules, followed by self-configuration and finally autonomous operation of the EtherCAT bus real-time loop. Additionally, the driver package supports the user PLC to manipulate EtherCAT data in real time, implements fast real-time (single cycle) slave-to-slave communication (skipping EPICS layer or PLC completely), features guaranteed one-shot trigger signals otherwise not supported by EPICS and much more. All the standard EtherCAT functions are supported, including the complete reprogramming of slave configurations and configuration generation for programmable slaves, such as EL6692 and EL6695 network bridges.

	With its four accelerator facilities the Paul Scherrer Institut (PSI) has already several decades of control system Input Output Computer (IOC) experience. The technology is moving forward fast. The older hardware is becoming obsolete: it is slow, consumes too much power, does not match new computing, networking and bus technologies, and replacements can no longer be purchased as models have been discontinued.
